Which Are The 15 Most Popular Plastic Injection Molding Materials?
Plastic injection molding is a manufacturing process for producing large quantities of plastic parts. The process of injection molding consists of injecting molten material into a mold cavity, where it is left to cool and harden into the desired part shape. Different types of plastic materials are used in the production of plastic injection molded parts, each with its own unique set of properties.
With so many different materials available, it can be difficult to decide which one is best for your application. To help you make an informed decision, we’ve compiled a list of the 15 most popular injection molding materials and their key properties.
