Heston Automatic Screen Changers are used on thermoplastic extruders. The unique design of the Heston Changer minimizes residence time and possible plastic degradation by mounting directly on the threaded end of the extruder barrel and attaching directly to die connectors, eliminating intermediate adapters and extruder gates or flanges. Overhung load is greatly reduced, eliminating the need for a separate stand for the screen changer. Contact us if you’re looking for replacement parts.
