Injection Molding: The Quick Design Guide - Fabbaloo

A standard two-part injection mold cannot create an undercut; when the thermoplastic cools, the material will prevent the mold from opening. Depending on the shape of the object, designers use a variety of methods to get around this problem. External undercuts can be created if the parting line of the mold is moved to intersect with that area.

Mold Design and Tooling for Injection Molding

Injection molding is a high-precision manufacturing process that injects molten plastic into a carefully designed mold, where the plastic cools and hardens into the specified part or product. The piece is then ejected from the mold, either as the final product or as a near-final product that is sent on for secondary finishing.
