Family and Multi-Cavity Molding Servic
Maximize each mold shot by producing multiple identical or different parts in one cycle
What is Family and Multi-Cavity Molding?
Family molding and multi-cavity molding are efficient techniques for producing multiple parts in a single injection cycle. Multi-cavity molding uses identical cavities to yield numerous copies of the same part. In contrast, family molding incorporates different cavities within one mold to produce complementary components—such as left and right parts—simultaneously.
