Reducing Shrinkage in Plastic Injection Moulding using Taguchi Method in Tata Magic Head Light

Mohd. Muktar Alam | Deepak Kumar ^[26]

Abstract: Injection moulding has been a challenging process for many plastic components manufacturers and researchers to produce plastics products meeting the requirements at very economical cost. Since there is global competition in injection moulding industry, so using trial and error approach to determine process parameters for injection moulding is no longer hold good enough. Since plastic is widely used polymer due to its high production rate, low cost and capability to produce intricate parts with high precision. It is much difficult to set optimal process parameter levels which may cause defects in articles, such as shrinkage, warpage, line defects. Determining optimal process parameter setting critically influences productivity, quality and cost of production in plastic injection moulding (PIM) industry. In this paper optimal injection moulding condition for minimum shrinkage were determined by the DOE technique of Taguchi methods. The various observation has been taken for material namely Polypropylene (PP). The determination of optimal process parameters were based on S/N ratios.
