CPM Extrusion Group designs and manufactures side feeders, vent stuffers and die head assemblies as direct replacement parts for most OEM extruders.
Side feeders are available with screw diameters from 25mm through 133mm for feeding solids downstream into the extruder to support a wide variety of applications and installation requirements.
Strand Die Assemblies and Replacement Die Plates
CPM Extrusion Group has developed a robust line of strand dies for maximum productivity and efficiency. Our E-Series dies uses a modular split-body design, allowing different rheology compounds to run on the same die body by simply changing the upper-body flow channel. The wedge-lock die plate design and quick-release die adapter connection facilitate fast changeovers.
Strand dies can include an integral breaker plate for fixed screens as required.
Replacement die plates from CPM Extrusion Group are available in a wide range of metallurgies, providing extended service life when processing the most abrasive materials.
CPM Extrusion Group vent stuffers are designed to retain the molten material within the extruder screws while allowing gases and vapors to flow through the screws of the vent stuffer.
Stuffers can be operated at atmospheric conditions or under vacuum, depending on the requirements of the process. Vent stuffers provide stable degassing at high production rates for many compounding applications. The initial cost for the stuffer is recovered quickly since there is no longer down-time associated with cleaning of the vacuum vent port.
Stuffers can be installed in the top of an open barrel or on the side of the extruder using a combi or side feed barrel.
