Abstracts: Now a day’s demand of plastics product is very high because of their better quality, design and appearance in comparison to other material product. The use of best operating parameters is needed to produce better quality of plastics product. This paper deals with the effects of parameters selection on injection moulding using Taguchi. The objective of this paper is to define suitable parameters in producing plastic product in term of strength. The paper describes the effect of temperature, pressure and cooling time. Plastic material polycarbonate was studied in this paper which commonly used in industries. The operating parameters have to be correct and can produce better product. There is changes occurs in product with change in parameters. Optimum parameter is related to the quality to produce product without defects such as short moulding, flashing and others.Plastic product (Tea Plate) of polycarbonate plastic material is produced injection moulding machine with different melt temperature, injection pressure, and cooling time. Tensile strength test of each workpiece has done with Tinius Olsen H10K-T UTM.
