ABSTRACT
Injection molding and extrusion ranks as one of the key processes for the production of plastics components. It is a rapid process and is bring into utilization to produce bulk of identical products ranging from high precision engineering articles to disposable consumer products. As of late, the production of plastic items has expanded quickly in light of the fact that plastic items are low in price, light in weight and quick for shape framing, along these lines making them more in vogue than the metallic products. As a result of mounting plastics applications, growing customer increased, the quality prerequisites of injection molded items have turned out to be progressively extreme. The setting and optimization of key process parameters are acknowledged as important means to deal with liven up the quality of the molded items. Inappropriate or unseemly settings of parameters normally create quality and production issues. Minute changes of significant molding parameters may give an extensive effect to the plastic product’s characteristics and this research paper is also anticipated to lend a hand to the optimization of parameters of vertical plastic injection molding process. In this study, the plastic product has been fabricated using a mould designed in our labs that shows an improved surface roughness which suggests that molding conditions play a vital role in quality of these products.
