Family molds are used in injection molding to produce multiple different parts in one cycle using a single mold. This article explains how family molds work, their advantages, engineering challenges, runner balancing, cooling design, shrinkage control, and when they should not be used—especially for optical or high-precision parts like automotive lighting. It also shows how Guangdian Technology evaluates whether a project is suitable for a family mold through DFM and moldflow analysis to ensure both cost efficiency and product quality. Read More
