The Extreme Coatings division of Surface Engineering & Alloy Co., based in St. Petersburg, Fla., is trumpeting the results of a wear-test comparison performed by one of its customers, Blue Water Plastics Inc. of Marysville, Mich.
The test compared CPM9V tool steel to a screw treated with Extreme Coatings' XC1000 material. Extreme Coatings reports the CX1000 screw has a life of two or three times the tool-steel screw.
Blue Water processes 35 percent long-glass-fiber-filled nylon.
In April 2001, Blue Water replaced the tool-steel feed screw on one of its injection presses with one made with Surface Engineering's XC1000 material — a composition of cobalt saturated with tungsten carbide. The screw recently was pulled for inspection.
Another press still was running the same material on CPM9V steel.
