Screws

An optimal extrusion process depends on the extruder screw design, and the quality of manufacturing the screw. It cannot be overstated that the screw design and quality is critical to your success. Our designers, engineers and machinists understand what it takes to design and manufacture extrusion screws that perform best for our customers. We manufactures barrier screws, mixing screws, general purpose screws, volume reduction screws, and more.

Selecting the right extrusion feed screw design for your process is critically important to optimizing melt conditions and maximizing your material properties. Plastic materials have broad variations in viscosity, melting points, volatiles, densities, moisture, sensitivity to shear, abrasive contaminants, etc. All of these variables, alone or in combination present significant barriers to maintaining homogeneity and melt consistency and output.

We can help you choose the optimal extrusion screw design for your process. From single-stage general purpose to two-stage barrier designs to double vented and with a host of mixer technologies and wear-resistant alloys, we have what you need to maximize your process. We have everything from low work to high work screw designs that work to keep your resins in proper condition.
