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 by in our white paper.
Without changing your molding press or tonnage, a stack mold increases productivity and reduces your part costs by using a stack of multiple mold layers. Simultaneously closing all layers in the stack enables molding all parts, in all layers, in one shot. In addition, the molded parts can have a different geometry. A1 was one of the early innovators of stack molds in the 1960s, and our experience qualifies us as experts in stack molds.
Concerned about cost? Don’t be. A stack mold can reduce the need for multiple molds and multiple presses, providing immediate and exponential cost savings.
A1 has refined stacks with proprietary self-supporting center racks and innovated all the little details that prolong the life of a stack mold. Not sure if your part qualifies for a stack? Contact us.
The customer needed to increase throughput based on consumer demand for a plastic roof ridge vent. Rather than running two molds in different presses, A1 engineered a stack tool that virtually doubled capacity in a single press.
