Stack Molds

Stack molds increase productivity by using a "stack" of multiple mold layers. Closing the plastic injection mold simultaneously closes all layers in the stack, simultaneously molding all parts in all the layers. Using the stack molding concept, productivity can be increased two, three, or even four times in some cases. The tonnage required of the molding press does not increase with more layers. Planning for future expansion, a stack plastic injection mold may even be engineered and built to allow for adding layers to provide higher productivity.

Tandem Molds

Similar in concept to a stack mold, a tandem or toggle mold alternately runs one layer or the other. While one layer is filling and molding parts in its cavities, the other layer is ejecting its parts. This plastic injection mold design allows for different parts and designs to be run in each layer, using different shot sizes or plastic volume in each half.
