Polymer Processing Solutions

Screen Changers, Gear Pumps, and Custom Systems for Polymer, Rubber, Chemical, and Hot Melt Adhesive applications. PSI’s flexible design vision has always been through the eyes of our customers – combining the benefits that drive production and profitability for plastics extrusion and hot melt adhesive processes with how the extruder operators use them.

Manufacturers facing tighter production tolerances and rising material costs need equipment that supports efficiency without sacrificing product quality. PSI works closely with processors to optimize melt flow, reduce downtime, and improve consistency across demanding extrusion applications. By combining technical expertise with responsive support, we help our customers extend equipment life and maintain stable throughput in high-volume environments. Our team can evaluate existing lines, recommend performance improvements, and develop customized upgrades that align with long-term production goals.

These polymer processing equipment solutions are designed to support cleaner operation, better pressure control, and smoother integration with downstream equipment. Whether supporting recycling operations, specialty compounds, or high-output manufacturing lines, PSI delivers polymer processing solutions that improve processor reliability, minimize waste, and achieve operational flexibility in competitive markets.

For polymer and hot melt adhesive filtration requirements, PSI Screen Changer types include Backflush (CSC-BF), Continuous dual-piston (CSC), Discontinuous single-piston (DSC), Hydraulic Slide Plate (HSC), Manual Slide Plate (MSC), and In-Line Filters (ILF).  For large polymer reactor and compounding lines, PSI offers Extended Area Continuous Screen Changers (EAC). Gear Pump types include: Extrusion Gear Pump (EGP), High-Pressure Gear Pump (HGP), Chemical-Industrial Gear Pump (CIP), and Fluoropolymer Gear Pump (FGP) for fluorinated plastics.
