Product catalog summary
Overview
The KCH Continuous Hybrid Screen Changer is a melt filtration solution designed for plastics extrusion. It combines features from previous KC and KCN product lines to provide uniform continuous extrusion pressure with minimal variation, enhancing production efficiency by reducing process interruptions and scrap.
Specifications
  • Uniform extrusion pressure variation of ±20 psi.
  • Hydraulic puller action for rapid response to contaminant level changes.
  • Standard RDW screen with reliable water-cooled seal design.
  • Accurate control of extrusion pressure and screen use measurement.
  • Automatic screen shear system and custom bolt pattern for flange adapters.
Features
  • Instant screen movement on command, independent of material properties.
  • Less maintenance required due to the absence of heaters for screen indexing.
  • Wide range of applications including pipe and profile, film and sheet extrusion, polymer compounding, and blow molding.
Options
  • KCH Standard: Superior polymer flow distribution and efficient filter media use.
  • KCH Twin Screw: Designed for twin screw extruder barrel configurations.
Technical Parameters
  • Maximum contaminant size: 0.360 inches (9.1 mm).
  • Extrusion pressure range: <5000 psi (standard), <4000 psi (twin screw).
  • Melt temperature range: <600° F.
  • Sizes available: 1.0” (25 mm) to 8.0” (200 mm).
  • Throughput: <15000 pph.
Applications
  • Suitable for most polymers including HDPE/MDPE, PS, PP, and PET.

KCH Continuous Screen Changer-1

KCH Continuous Hybrid Screen Changer In plastics extrusion, having the right screen changer for your material’s filtration requirements can make the difference between profit and loss. Parkinson Technologies’ line of Key Filters products offers custom engineered solutions and turnkey services to meet melt filtration needs for most thermoplastic materials. The new KCH joins the best features of the prior KC and KCN product lines delivering the same uniform continuous extrusion pressure, varying as little as ±20 psi. With hydraulic puller action, the KCH can react rapidly to disruptions caused by varying contaminant levels allowing for more flexibility with material supply. No process interruption translates into increased production and decreased scrap, bringing maximum efficiency to your extrusion operation. Standard Melt Filtration Process Extrusion Pressure Profile 2000 Key Filters KCH Continuous Process The KCH Continuous Hybrid Screen Changer offers a smoother more consistent pressure profile for a better product at a higher overall yield.
