Mainstream polymers are versatile enough to perform a large number of applications. Still, sometimes custom or specially built molded parts – such as for medical and public safety industries – have requirements that some commodity plastics just can’t meet. If a part needs to stand up to harsh conditions such as chemicals and fire, often engineering-grade plastics are the most viable solution. To understand how the application of these special plastics can minimize failure risk and achieve unique specifications, let’s review engineering-grade resins in plastic injection molding.

3 Considerations When Designing a Plastic Molding Ejection System
When plastic parts become stuck in a mold, it can result in part defects, breakage of mold components, manufacturing delays, and increased costs. That is why carefully designing an efficient ejection system is key to achieving optimal output and final quality products. To design a system that ejects parts easily, quickly, and consistently, the engineer should pay considerable attention to the ejection surface area, the location, and the ejection type. Let’s take a closer look at these three considerations when designing a plastic molding ejection system.
