Extreme Coatings' high velocity thermal spray coatings of tungsten carbide provide exceptional wear and corrosion resistance to any injection molding or extrusion feedscrew. The finish coating layer is crack-free with hardness from 65 to 72 HRC. Our mirror polish surface finish has a low COF which improves screw cleaning and this hard layer will not scratch. We engineer, design and manufacturer coating solutions to improve a components (part) performance and service life. For example with our formulas applied to feedscrews and mixing rotors they can last 2, 3 and 4 times longer. Come see why we coated over 42,000 parts!
Cutting Edge Wear Resistance Technology for the Plastic & Rubber Molding Industries
Our high percentage of hard tungsten carbide particles provide maximum abrasion and adhesive wear resistance.
A 99% dense coating layer provides exceptional corrosion resistance and our mirror surface finish ensures easy purge clean between material changes.
