HYDRAULIC DIE CHANGER This HDC from PSI-Polymer Systems uses a quick-shift slide plate to exchange die heads on a single extruder.
WHAT'S NEW? The patent-applied for system is well-suited for lines that must be purged during die changeovers, such as foam sheet operations or for batch operations. Designed for tight spaces, the current model will accept 12-inch and 18-inch annular dies. Custom versions are available for virtually any extrusion process, such as pipe and profile, where dies are routinely changed out.
BENEFITS Reduced changeover times translate directly to increased output and cost savings for waste and labor reductions. The device provides a pre-heat zone for the new die and uses a hydraulic power unit to shift the die on-line, effectively reducing changeover times from one hour to one minute.
