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.
