Stack molds can nearly double the output of a molding machine when compared to a single face mold.

CACO PACIFIC started with a multi mold project for Polaroid film packs back in 1963. Ever since that time, stack molds have been a considerable percentage of our annual sales.

By including our proprietary Hot Runner System, your stack mold will benefit from a single source integrated design.

Our engineering teams work together to design a system that is easy to maintain both in the press and on the bench.
