Abstract. Metal injection moulding (MIM) has gains much attention due to its ability in producing large amount of small part with complex geometry and intricate shape. In order to obtain better shape retention, optimum density of green part is required. This paper deals with the application of Taguchi method in optimising the green density of moulded components base on parameters setting in plastic injection moulding machine. For this purposes only 7 process parameters were considered here are injection pressure, injection temperature, cooling time, injection speed, injection time, packing time and mould temperature. An orthogonal array of L27 experimental base design was conducted. Base on the experimental results, cooling time plays significant contribution to density followed by injection pressure, time, speed, mould temperature, packing time and injection temperature. Confirmation test was done base on optimization level for each factors and shows good results in green density of the injected moulded samples.

“…It has been well established as it inherit many features compared to powder compaction such as low production cost at large quantity, good tolerance & mechanical properties, applicable to many materials and ability to sub-micrometer regime [2,3,4]. However there is some limitation in the process such as feedstock preparation, debinding and sintering [3,5]. For this project, High-density Polyethylene will be mixed with nano clay.…”

Abstract. Injection molding is one of the most important processes in manufacturing nowadays. Thus, attention must be given towards the optimization of the product defects. Parameters have been chosen by screening tests to improve the process quality. The main purpose of this study is to optimize the processing condition using Taguchi Method on shrinkage for HDPE-Clay specimen. The experiment starts by preparing the mixture between HDPE and clay. Then, screening test is conducted to obtain the parameters. The parameters are melt temperature, injection speed, injection pressure and cooling time. By using the array orthogonal L 9 (3 4 ), signal to noise ratio and ANOVA were conducted. Based on the S / N ratio analysis, best combination can be produced for warpage (melt temperature: 190 o C, injection speed: 40%, injection pressure: 30% and cooling time: 3 seconds). While for ANOVA, melt temperature is most significant with 60.28% for warpage.

“…Optimization methods alone or integrated with other methods provide very effective techniques in finding the best process parameters values leading to least warpage, shrinkage, distortion and other defect. While in the other hand, it increase the output quality by the contibution percentage [1][2][3]. For this project, High-density Polyethylene will be mixed with natural fibres nano composites which is kenaf.…”

Abstract. Injection molding is probably the most important method of processing of consumer and industrial goods, and is performed everywhere in the world. In this paper, Taguchi Methods was used to define the optimization of process parameter for an injection molding machine to produce a dumbbell product from High-density Polyethylene (HDPE) + natural fiber (Kenaf). Taguchi Methods with L9-3 4 approaches will be used in this work where two different formulation of material will be tested to find the best formulation and its parameter setting. Here, an orthogonal array (OA) and signal-to-noise (S/N) ratio are employed to analyze the effect of injection molding parameter. The significant of formulation and parameter setting from injection molding will be evaluated through the strength value of the specimen. Standard ISO R527-2 test method will be used. Results show that changes in the parameter setting will give different tensile strength value. The optimum parameter setting was set based on the S/N ratio. For each formulation, optimum parameter setting has been achieved by using highest mean S/N ratio and it can be calculated manually or by using Minitab software.
