Plastic Parts Design Guide

When designing plastic parts that will be injection molded, you might have questions about design criteria. For example, what draft angle ensures the part’s easy ejection from the mold.Below is a guide to the most common criteria for designing plastic parts. Wall Thickness The wall thickness of a thermoplastic part depends on several factors. These factors include …

Mold Engineering Design consideration for Plastic Injection Molding

The core and cavity are often referenced as the Aand B sides or top and bottom halves of a mold. A core-cavity approach to part design can savemanufacturing time and money and improve theoverall part cosmetics.Let’s say you’re designing a simple box. When draft is applied to the outside and inside surfaces in the same mold half, you create a very deep rib that is difficult to manufacture and increases tooling costs.
