WHAT IS A STACK MOLD AND HOW DOES IT WORK?
Stack molds can increase productivity by up to four times in some cases. See how in our white paper.
Also known as toggle molds or T molds, tandem molds are a variation of a stack mold, with alternately filled layers. While one layer is filling and molding parts in its cavity (or cavities), the other layer is ejecting its part(s). 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. The popularity with this mold type is with family parts for assembly and longer cycle time components.
When you want to improve your cycle times and reduce your press time on slow cooling parts, a tandem mold is the way to go.
Tandem molds are similar but different from stack molds, where one cavity is being filled at a time.

The customer’s part was taking too long to cool, thus wasting valuable press time and money. A1 engineered a tandem mold in order to run two parts in sequence from the same press and from the same mold.
