StackTeck announced unconventional application for big stack mold


StackTeck announced an unconventional application for a big stack mold with Quick Product Change (QPC) features. This mold runs 2000 tons of production in a 1000-ton injection molding machine, in a 2x4 format enabling molding of eight large, flat panels per cycle of the machine.

StackTeck's client selected the QPC approach with manufacturing flexibility in mind. According to Angelo Morra, business development manager at StackTeck, "This customer was looking for a way to mold multiple part types using the same machine and they have achieved a change-over time of less than one hour using StackTeck's proved Quick Product Change technology. They are using high performance Husky 1000-ton injection molding machines, and with stack mold technology they have reduced the number of machines needed for the program by half."

A QPC mold is designed with two major components: frame and modules. The frame is designed to remain in the machine with all water, air, and electrical hookups remaining in place. The modules consist of core/cavity assemblies and p0late systems. Every QPC mold can be converted from single fact to a stack mold configuration. The QPC approach has built-in features for the alignment of modules to the frame, as well as plate-to-plate connections for services. This dramatically reduces change-over time, Morra explained.
