Introduction When designing a new component through injection molding, one of the most important questions engineers face is:Which plastic should I choose for my application? The material selection process determines not only the mechanical strength and durability of a part but also its cost, manufacturability, and compliance with industry standards.

Introduction Injection molding is one of the most versatile and widely used manufacturing processes. From automotive parts to consumer products, medical devices, and industrial components, millions of parts are produced daily using this method. A key factor that determines performance, cost, and durability of molded components is thetype of plastic
