2000t of production in a 1000t machine is the result of an unconventional application for a big stack mold with Quick Product Change (QPC) features announced by StackTeck. This mold runs in a 1000T injection molding machine, in 2×4 format enabling molding of 8 large flat panels per cycle of the machine.
StackTeck’s client selected the Quick Product Change 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 1 hour using StackTeck’s proven Quick Product Change technology. They are using high performance Husky 1000T 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 2 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 plate systems. Every QPC mold can be converted from single face 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.
Some of the advantages of the QPC technology are:
- Ability to fulfill last-minute demand changes from customers
- Only one hot runner and frame needed per machine
- Reduce product change-over times / maximize production up-time
- Growth of capital investment can be “cascaded” with “module-only” purchases as the market demand increases
- Standard QPC module heights and part pitches facilitate the use of robotic standards
- Identical modules can be moved between multiple frames including a single face frame and stack mold frames up to 4 levels.
