Logistic and Supply Chain Management

The data analysis in the waste and defects of the injection process of plastic manufacture is majorly qualitative. The analytical process evaluates and assesses the negative Impacts of the plastic to the productivity and in enhancement of the economical issue of a company process as an overall example of the whole issue. The Pareto rule (rule 80-20) comes in handy in the analysis process of the work (Campbell, 2009, p.11). The study selects Salee Industry Public Company Limited as a case study in order to conduct this research. The Pareto rule analysis of the study indicates that 80% flood incidences is because of the plastic companies in the Thailand. However, the number of the plastic companies is 20% of the total sum of the industrial companies in Thailand. Various industries such including the automotive, agriculture, consumer goods face numerous effects from excessive flooding crisis (Campbell, 2009, p.156). The country has many businesses located around Ayutthaya and PathumThaniareas. The flood crisis led to the discontinuation of their operation during this crisis. It is fortunate that Salee Industry Public Company Limited is one of the minority manufactures that can go over this situation however; its effects have magnitude effects on the entire production of the plastic in the region. It supplies several companies with final plastic products, therefore, contributing to the compounding of the plastic problems.

Approximately 20% of the plastic production in Thailand emanates from Salee Industry Public Company Limited but it contributes 80% of the plastic waste in the country. In contrast to size and magnitude of the Salee Industry Public Company Limited, this needs action (ASM International, 2009, p.80). The method of plastic production Salee Industry Public Company Limited applies is questionable in considering the effects plastic expose the environment in to. The study assesses the vital ways of the reducing wastes and defects from production plastic production, therefore, analysis of wastes and defects in the plastic injection that the company deals with are important (Goodship & Rapra Technology Limited, 2010, p.38). Injection mode of production leads to the wastages in the plastic use. This promotes adverse loses in the resources and eventual production of environmentally unfriendly products. The company invests hugely in the Injection molding process. The process attracts several wastages in production of the plastics. Injection manufacturing has numerous setbacks that increase the production wastes. These constitute the presence of the Black specks spots and streaks on the manufactured products. These specks emerge due to several causes including the Plastic materials burning on the cylinder walls. A mixture of the melt and the flakes merge to form undesirable products (ASM International, 2009, p.84).

The processors then decide to shade off these products as in most cases the initial function of the products is not achievable. Air trapped in the mold causes the burning of the melt or the flakes (Packham, 2010, p.40). This is evidence to the partial burns on the walls of the injection cylinder. The burns propagate existence of unattractive portrayal of the cylinder. It is dark and sooty. The material loses of the in the manufacture attributes to immense financial loses to the company. The method is not advisable for the short-term production basis (Conference: Injection Moulding, 2010, p.20). This is due to unimaginable financial restriction it entails in the process of investing in its assemblage and commissioning. The bubbles are eminently common in the finished products. It is ordinary finding unusable injection products due to the extensive products hollows. The hollows and the bubbles generate due to the presence of moisture in the plastic granules.

Moisture elimination is tremendously challenging to eliminate because the products have moisture from their sources. Flashing destroys the production of the required products specifications (Conference: Injection Moulding, 2010, p.27). This is due to the ordinary conditions like high temperature of the materials. The precise temperature regulation is a hurdle since the heating occurs in the tube. The management of the internal pressure proves to be unworkable in some circumstance adding on the occurrence of the flashing. The poor finish of the products makes some products unsuitable for applications. Presence of pores in the fluid containing vessels means failure to the product. These products are the recipe for the extensive material wastes. The presence of the pores on the mold and using them when they are too cold constitutes to the pores. Goodship in his book Practical guide to injection molding attributes the cause of the pores to low pressure. He adds that the presence of the water on mold faces and the inclusion of excessive mole lubricant contribute to the formation of the pores. The other common cause of the poor plastic products is the presence of the short shots (Parmenter, 2009, p.58). Goodship argues that this is the result of the cold molds. This makes the formation of the premature solidification. It facilitates the occurrence of a high resistance to flow for the melt. He admits that other cause of the condition is the low pressure.

Too small gates and imbalance of the propeller amplify the effects. Other causes of the poor results to products are the sink marks, warping and the surface marks. The production capacity of Salee has the contribution of the 41 machines for operating injection molding. This constitutes a process ranging from 18 to 650 tons clamping force and7 machines for the vacuum pressure forming process. However, due to the high demand from our customers, Salee runs the production from all machines 24 hours per day with 7 days per week in order to reach customer's demand. The current production capacity has the average production capacity of the company of around 3.1 million units for injection molding. The company has an average of 1.2 million units of vacuum pressure forming process (Parmenter, 2009, p.50). The 20% of the products that contribute to the 80% of the sale in the January-09 are the black dot 16793, burn mark 1948, scratch 3700, white mark 9339, flow mark 7620, and the weld line 9339. They contribute to the 72% of the total sales for the company.

The significant number of products for the company runs to about twenty-eight products. The products are flash / Bari / hair flash, short mould / short shot, sink mark, pin mark, white mark, silver, weld line, flow mark, scratch, material flow, burn mark, black dot, over cut crack, broken, wrong color/discolor, oily, red dot, bending / warp, water mark, dent, air bubble, gate NG, mixed part, mould mark and shining/not shining. For the February, the 80% contribution to the sale by 20% of the products black rot 18113, scratch 2598, flow mark 4818, weld line 5685, other 3372 and the tech adjust 2378. In total, they contribute about 73% of the sum of the products. This resembles an almost 80% of the sale considering that the contributing products are the six. Six of the twenty-eight products are about twenty-one percent of the goods. On the month, of March, the contributing items are flow mark, black dot; weld line, flash/Bari / hair flash and the tech adjusts. The assessment of the table reflects that the in all the months the black dot, scratch, weld line, white mark, other, tech adjust and the sink feature as the products that facilitate the high sales in their respective months. They are the 20% that determine the 80% of sales in the outlined months.

Salee similarly faces the problem of wastes and defects. This emanates from the production process. Wastes from production create numerous faults in the process. The wastes and defects create many expenses. They include the problem like s raw material cost, utility cost, wages and salary of employees. In addition, the company faces negative images and reputation from customers when the customers receive lots of defects and wastes. This will lead to the decrease of customers' satisfaction toward the company. This attracts the mindset of having to find a solution the main concern in this case (Mutsuddy & Ford, 2010, p.47). The plastic materials harbor different properties that attribute to the selection of the various materials for use. This categorization includes Strength advantages, rigidness, excellence of fatigue resistance, bosom creep resistance, chemical effect resistance, moisture and water resistance, the transparency and the opaque of the product, the cost of the products. Salee faces the problem of wastes and defects that surface from the production process. Wastes from production create numerous faults in the process. Moreover, the wastes and defects are generated many of expense such as raw material cost, utility cost, wages and salary of employees. In addition, the company will face with the negative images and reputation from customers when the customers receive lots of defects and wastes. This will lead to the decrease of customers' satisfaction toward the company (Mutsuddy & Ford, 2010, p.45).

Mr. Rosato of Plastics Institute of America in his book Plastics engineering, manufacturing and data handbook, admits that the collection of loss and defect data in a structured way is tremendously significant in a step towards improving performance of the plastic company. Salee Company Limited suffers this setback. Therefore, it should align itself in a position to maximize profits by looking in to the ways of reducing the loss. Mr. Somsak Pruksawan of the Salee Industry Public Company Limited admits that every organization, large or small businesses suffers various types of obstacle when performing businesses. Their problem is the management of the waste and the plastic defects. The management of the company notes that the company faces various difficulties. These problems range from the upstream of supply chain processes to the end customers or the consumers of their products. The material cost varies with the mass of material that that facilitates the process and the price unit of that material. The heaviness of material is vividly a result of the proportion volume and material density. However, the fraction's maximum wall widths play a role (Lindsay, 2010, p.57).

The weight of raw material that fits in this research includes the material that fills the compartments with the mold. The size of those channels, and hence the amount of material, largely changes along with the thickness of the part. In an attempt, to check the financial spending for any company and evaluating how valuable it is to assess the costs it is worth categorizing the production cost in to various subgroups. Pareto rule acknowledges that to check spending then an individual should rearrange his resources and the expenditure to determine the appropriate balances. Noting of the 20% of the investment that control or consume 80% of resources is vital (Goodship & Rapra Technology Limited, 2010, p.38). Production cost and the tooling cost are the most widespread expenditures on the production of the plastic products. The companies calculate the production cost in terms of the hourly rate. This is possible in the analysis of the cycle time. The calculation in the hourly rate is usually proportional to the magnitude of the injection-molding machine applied.

The amount of the material passing through the injection molding machines gets the analysis in considering the tonnage of the fastening force they offer. The products lost in wastes and defects, in tonnage amount to 80% of the company loss. However, the clamping force varies by change in the projected expanse of the fraction and the stress with which the substance gets the injection. The cycle time divides into the injection session cooling duration and resetting time. In reducing these factors, the production expense lowers (Gordon, 2010, p.37). However, the injection time decreases in reducing the utmost wall thickness of the fraction and section of volume (Groover, 2010, p.30). The numerous thermodynamic qualities of the material influence the cooling time. The resetting time clings on the machine size, in addition to part magnitude. Noting from the skills in the plastic injection molding processes, Mr. Somsak states that in the beginning when they started doing the business, they did not have initial capital to invest in the fully automatic injection machines. These that workforce were the chief sources that they applied in their operation processes. The defects are not easily controllable by human intervention noting that the operation involves an enormous amount of heat releases. He adds that it was unfortunate the company had challenges originating from human errors in the production processes.

There are various errors that occur from human such as incomplete in melting of plastic ball before inject into the mould (Malloy, 2009, p.90). In addition, the material deficiencies in molding machine barrel heating duration causes a timely manner suitable to the mould melt. Moreover, the workers release the injection machine before the plastic part is cool and set. It is in the form of the die. This creates the defects and losses during the production activities (Osswald et al., 2009, p.97). Later, the company has to improve the operation process by investing a vast amount of investments in the high technology machines. Pareto rule suggests that works input determined the success of the 80% of the profits accruable from the manufacturing process. The interview with production managers and assistant production manager of sale reveals that both waste and defects are a considerable problem that an individual cannot eliminate from the production processes. He contends that their company had invested in high technology automatic machines (Osswald et al., 2009, p.90). They argue that defects may occur from human error or even the error from the injection machines.

Salee Industry Public Company Limited has set up the quality control division in order to check the quality of the parts before submitting the orders to their valuable customers. He argues that initiation of the control unit results in fluctuation and falling for wastes that emanated from the company.

The analysis of the defects and checking an appropriate remedy relies on the evaluation of the nature of the product defects and the wastes (Malloy, 2009, p.98).The roles that customers and the manufacturers play in the process of production are fundamental in determining the effect of the defects and wastes in the production process. The management of sale provides for the customer to order plastic ball or plastic sheet that use in production by himself or herself. They may choose to let Salee procure raw materials from own suppliers. The customer suggests type and quality of raw material that they are required to use in production. They explain that at present, the proportion of raw materials supplied by customers and Salee is around 30:70 of total raw materials applied in the production. They import approximately 90% of the total material from Thai and Japanese suppliers who have manufactured in Thailand Muccio, 2009, p.79). The lose emanating from the production reads malice to the customer if suppose he bought the material. Avery in his book Injection molding alternatives: A guide for designers and product engineers contends that Injection Molding process is a chief processes for manufacturing plastics items. He acknowledges that the process depends on the use of an injection-molding machine.

The operator pours the raw plastic material into plastic granules (Bryce, 2009, p.49). Heat application takes place melting the substances. A reciprocating screw injects the semi-liquid material in the injection molding machine vacuum Muccio, 2009, p.78). The quality control process for the injection mode of the production is essential in regulating the wastes. It aids in the checking of the expanse of the defects derived from the production. Training of the workforce is fundamental in achieving the limits the y should achieve in their work (Rosato & Plastics Institute of America, 2010, p.123). Some workers negligently decide to work low beyond their expected capacity leading to poor and undesirable quality of work. The quality control unit helps in the management of the Sink Marks, Gas marks or burning, Flash, Short shots, Knit Lines as known as weld lines, Splay and Flow marks (Lindsay, 2010, p.56). The solidification of the outer skin facilitates the formation of the sinks .it is common that the inner fraction of the material remains molten or viscous. This process of unregulated cooling leading to the sink marks on the surface of the material products. Campbell explains the best ways of the checking the problem ensuring the consistency on the wall thickness of the product manufactured. Adjustment of the molding parameters is indispensable in the preventing the proceeding of the defects. Gas marks on the materials emerges from the effects of the air on the vacuum cavity of the molder (Goodship, 2010, p.50). Lack of spaces for the escape the air prompts the formation of the gas marks on the products. The creation of the vents in the mold facilitates the regulation of the gas marks. However, the adjustment of the screw speed and its alteration reduces the burning of the materials. The flashing problem arises when dual halves of molds are not in contact together (Packham, 2010, p.40).

To achieve the vital parameter of the products the manufacturer should push the sides together. The regulation of this problem is achievable in t he efficient measuring and control of the tonnage. The proficient design of the mold is vital in the elimination of this challenge (Heissing, 2011, p.43). Campbell notes that some materials flash easily than other materials. This usually happens irrespective of the pressing of the mold. Poor flow of the molding materials in to the cavity prompts the formation of the Short shots (Rosato & Plastics Institute of America, 2010, p.40). Miniature flow of the materials prompts the poor filling of the mold. The manufacturer of the plastic products regulates the problem in controlling the injection mold parameters. Knit Lines arises if part of the mold has a hole. This facilitates the flow of the materials inside the hole facilitating the meeting of the two sides of the material mould. Reduction of this problem is achievable in adjusting processing parameters like the injection pace and mold hotness. Splay forms if the bubbles flow along with the flow on the surface in the plastic injection molding progression. This facilitates the formation of the marks on the product surface (Goodship, 2010, p.56). The control of the quality of the products and the continuous advancement of the materials is attainable on the Rebling Plastics tracks. This is only possible with taking care of the time for the process. Customer feedback assists in the evaluation of the possible opportunities for the advancement of the products. Formation of the material review board and recurrent meeting of the board is vital in analyzing the product quality.

The committee sets the possible ways treating the Non-conforming products. The repetition of this monthly facilitates the progression of the quality assessment. In the management of the problems, the board may decide on some changes of issues. The changes may inspection fixtures. The alteration of poke yoke fixtures facilitates reduction of the challenge (Heissing, 2011, p.30). Varying design of the manufacturing products aids in the design problem. He product quality. The committee sets the possible ways treating the Non-conforming products. The repetition of this monthly facilitates the progression of the quality assessment. In the management of the problems, the board may decide on some changes of issues. The changes may inspection fixtures. The alteration of poke yoke fixtures facilitates reduction of the challenge (Heissing, 2011, p.30). Varying design of the manufacturing products aids in the design problem.

The Salee's core business is renown of manufacturing mainly plastic products, via application of the dual crucial process of injection moulding and the vacuum pressure forming process. The business enterprise normally applies injection moulding in the production of both the thermoplastic accompanied by the thermosetting plastic materials (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465). These major parts of the production process of the materials entail the feeding of the granules materials into the heated barrel, mixing and then finally forcing the materials into the mould cavity where the finished substances cools and hardened to the desired configuration of the cavity. The prevailing customers that pertain to the injection moulding process are mainly subdivided into four principal sections that entail to the plastic components of the electronics that include scanner accompanied by the printer tray possessing noteworthy features (Reza, 2011, p57). This company deals with the later components possess exclusive right that pertains to the manufacturing of such products and located inland from the Toyo Jushi that is the greatest electronics vendor within Japan (Ram, 2005, pp172-180).

The second group entails the production of the appliance industry such as the microwave commodity, electrical measurements and the fax power switch off lights. The subsequent group of production of plastic parts entails the manufacturing of the plastic parts, including the motor vehicles accompanied by the plastic components that pertain to the industrial and the corresponding household products including water bottle and the lunch box at the quality grade. The vacuum pressure forming process is normally subdivided into dual groups namely the plastic packaging for the electronics accompanied by the appliances entailing the packaging of the electrical motors, aluminum tray, hard disk drive products and the material, integrated circuits (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465). The second group deals with the plastic packaging pertaining to the frozen shrimp accompanied seafood packaging and the corresponding laminate packaging.

The frequent flooding crisis within the Thailand has hampered the operation of the numerous automotive, consumer goods accompanied by the agriculture industries. The flooding crisis has affected the operation of the industries, which are situated in such as the Ayutthaya and PathumThaniareas (Ram, 2005, pp172-180). However, Salee Industry Public Company Limited is not affected by such situations but by the lack of the inadequate raw materials in manufacturing the products utilized in the management of the prevailing natural crisis. This subsequently causes the blockage the within the production of the process of the materials. Moreover, the company is encountered by the problem of the transportation during the period of shipping to the prevailing esteem customers. The production within the Salee Industry Public Company was thus discontinued the operation of the machine because of the drowning within its location, and this is despite larger demands of the products manufactured from the injection moulding process. The present capacity of the Salee Industry Public Company possesses a total of forty one injection moulding machines, thus aiding the company to perpetually operates throughout the week thereby supporting the massive number of demands emanating from the customers. Despite the full capacity of the Company, it is not capable of meeting the prevailing customers' requirement (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465).

The prevailing problems that are currently facing the Salee Industry Public Company pertain to the wastes accompanied by defects in the manufacturing process of the plastic parts, thereby creating numerous process errors within the existing process. The underlying problems that pertain to the wastes and defects in the production of the plastic parts as resulted to the generation of massive expense in the areas of acquiring the raw materials cost, wages accompanied by the salary of the prevailing employees and the utility cost. These problems of wastes and defects as consequently resulted to the negative publicity, images and the status of the Salee Industry Public Company amongst the esteem customers thereby leading to the decline of the contentment of the esteem customers to the Salee Industry Public Company (Reza, 2011, p57). The selected method pertains to the management dissertations that mainly entail the in-depth investigation within its requirement.

The prevailing case study embraces the analysis that pertains to the entity of the qualitative accompanied by the complex, and comprehensive terminologies that do not utilize frequently in the process of the unfolding over duration. The utilized methodology within the analysis entails single individual unit within the prevailing social movement and event. It mainly involves either the in-depth examination or the corresponding actual organization conditions entails the immersed decision making in countering the problem. They were consequently categorized into dual types pertaining to the individual's behavior and experience in solving the problem of wastes and defects. The second method is employed methodology entails the functioning of the social movements (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465). Moreover, the process utilized pertains to the actual, fundamental nature, investigation and the exploration of the present-day real life phenomenon via detailed, appropriate analysis of the inadequate number of events accompanied by the associations.

The prevailing case study method possesses numerous merits about the dissertation topic, which mainly involves that wastes and the defects eradication within the production of the Salee Industry Public Company. This is because the method is extremely elastic since it contributes to the exploration at the expense of the previous outlined assumptions within the underlying research. In addition, it enables the existing author openly study the prevailing issues that they are interested as pertaining to the improvement of the production methods accompanied by the eradication of wastes and the corresponding defects within the production methods. Conversely, the method utilized possesses demerits as it contains limited scientific applications as it solely small numerical subjects on the prevailing topic. The prevailing outcome of the tends to generalized the significant of wastes and corresponding defects that pertain to the production of the Salee Industry Public Company (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465). The method applied also consume a lot of time thereby acting as a drawback within the data collection process. Salee Industry Public Company is mainly focused in the process of eradicating the wastes, and the defects within the production process that would consequently results to the realization of the massive and long-term returns. The utilized techniques target the provision of the high quality goods with minimal production cost.

The prevailing gathering loss accompanied by the defect data within the structured mean is significant in the primary stages in advancing the performance of the Salee Industry Public Company Limited. This mainly entailed the determination of the prevailing wastes and the corresponding defects that are facing the Salee Industry Public Company Limited within the production process in the administration structure of the company thereby coming upon the immersed interaction with the production managers, accompanied by the assistant production manager within the company (Ram, 2005, pp172-180). It is thus realized that the reason that makes the Salee Industry Public Company Limited as pertaining to the cumbersome in the supply chain processes that majorly out spring from the difficulty concerning the wastes, and the defects within its operation. This subsequently resulted to the cumbersome in achieving the required demand of the esteem customers. There is the escalation and development of the automotive industry within the Thailand as compared to the preceding years thereby resulting to the augmentation of the demand of the vehicles within Thailand. This will consequently results to the massive benefits to the company as it is concerned with the production of the plastics parts via the application of the injection moulding process. Nevertheless, the success of the Salee Industry Public Company Limited is hampered by the flooding situation of its area of location thereby making the company not to compete favorable within the market. Moreover, this is further escalated by the internal problems that encompass the defects and the wastes emanating from the production process thus making it incapable of meeting the prevailing demand of the esteem customers in the marketplace (Rao,2010,pp579-585).

The major sources of the defects accompanied by the wastes that hampered within the production process of the Salee Industry Public Company Limited commenced at the start of the business since it was experiencing financial constraints (Ram, 2005, pp172-180). This subsequently posed a threat in the venturing within the automatic injection machines accompanied by the inadequate workforce within its business processes. Another result of the defects and accumulation of the wastes within the Salee Industry Public Company Limited was the prevalence of the human error within the manufacturing process. The errors realized in the production process emanates from the diverse errors due to incomplete melting of the plastic ball prior to inject into the required mould. Moreover, the prevailing the material deficiencies within the process of moulding apparatus barrel pertaining to the heating duration resulted to the recurrent of the timely manner suitable to the existing mould melt. Moreover, the defects and the corresponding wastes resulted from the release of the injection machine prior to the prevailing plastic section was cooled thereby making the injected product to die hence creating defect accompanied by waste within the production process (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465).

The error required within the production process eradicated gradually due to the improvement in the larger amount of capital within the high technology machines. This was done via the application of the automatic machines in aiding the production activity (Reza, 2011, p57). It was asserted that the defects and the corresponding wastes could not be eliminated within the production method since it resulted from the prevailing human error, and the error within the injection moulding. However, Salee Industry Public Company Limited instituted the quality control division that was mandated by checking the prevailing quality of the parts prior to submission of the existing orders to the esteem customers. The application of the later method resulted to the decline in the level of the defects accompanied by the wastes by 1.48% and 6.07% (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465).

Twenty-six types of defects and wastes loss were collected in the process of production accompanied by the quality control department (Reza, 2011, p57). Black dot defects is a rampant fault that normally takes place during the process of injection moulding process, and it is results from the thermal degradation of the prevailing plastic ball and the corresponding raw material that are mixed with the impurities in the process of the melting. Black dot contains approximately 32.73%, 27.43% and 22.24% respectively (Ram, 2005, pp172-180). Burn mark normally results to the section of the injection that is realized within the completed injection parts, and it is characterized by the presence of the small, dark brown dislocations marks on the prevailing plastic surface. Combustion during the production process normally results to the prevalence serious burn mark on the existing surface of the plastic injection parts. Scratch defect is considered to one of the major defects within the apparent injection moulding as it causes scratch of the existing injection molded sections, and it normally results to the insufficiency of the prevailing mould stiffness that is mainly responsible for defects in the process of injection moulding. It can also be resulted when the machinist unintentionally make scratches over the prevailing exterior of the plastic parts (Rao, 2010, pp579-585).

The material flow is mainly caused by the prevailing melting of the plastic balls accompanied by the pigments, devoid of fusing together of the spots that come from the exterior of the plastic parts. Either the extreme high temperatures or the extreme high humidity within the material majorly causes the defect that pertains to the air bubble during the process injection moulding (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465). Air bubble is normally found within the blemish areas trapped in the moulded plastic section, and it solely occurs when the air stuck within plastic moulding making it inflate thereby leading to the prevailing sections being discarded from the superiority control individual.

Within the Salee Industry Public Company Limited normally enhanced their product quality through adhering to the highest quality control procedures, that are established within the high quality control division department that is utilized in enhancing the comprehending the entire process that pertain to the quality control function and its principal responsibility (Ram, 2005, pp172-180). Salee Industry Public Company Limited utilized this department in granting elaborate explanation the Quality control methods that the company employs in the management of the quality of its products. The concept of quality control is utilized in the data analysis that pertains to the checking, and the reviewing of the prevailing plastic injection parts in that attempt to determine the appropriate products objectives to the esteem customers, which possess high quality, accompanied value within the injection moulded plastic products and services. This normally achieved via the holding of the meeting that are associated to the prevailing division involving the production department, transportation accompanied by the warehouse, department in the process of implementing the documented quality system that pertains to planning, organizing, measuring and perpetual advancement in quality product parts.

The data analysis pertains to the identification of the appropriate definition of the acceptable level of quality accompanied by the understanding of the operators and the conditions pertaining to the defects and the wastes that occur within the plastic parts (Reza, 2011, p57). The prevailing quality-checking schedule within the production order concerns checking the existing quality of the plastic injection parts within two hours (Ram, 2005, pp172-180). Moreover, the prevailing random samples originating from the run is utilized in checking the consistency of the existing quality all over the production process.

The employed quality control within the production does not usually interrupt the process of production, but focuses on the production staffs in matters pertaining to the uniform checking of the quality within the whole process. In case, the defects are detected within the prevailing production process quality control operators in the completed injection parts, the operator normally record the underlying problematic lot followed by the subsequent examination of the product quality that is managed intimately. The prevailing customer's factory are normally consulted in cases the in order to accept the prevailing defect by the quality control staff. If the customer declines to accept the prevailing defect that is pertaining to the work pieces, then the defect and the corresponding return material are kept in Salee Industry Public Company Limited as scraps (Lalit, Mallikarjuna & Sarcar, 2008, pp435-465). The prevailing scrap within the company is normally considered as the negative effects within the company since it normally involves many resources in the production process. The incurred cost in the production of plastic products that are normally affected when there is the existence of the scrap entail the material cost, utility expense and the labor cost. Defects and corresponding wastes within the Salee Industry Public Company Limited lead to the realization of lower returns, which subsequently result to payment of considerable higher expenses.
