Composite Coating Makes Glass Fibers Less Aggressive in Sliding, Turning Parts
Fiber-reinforced and mineral-filled compounds are not always compatible with use in dynamic applications, where parts slide, rotate, pivot, or move across each other. "When a glass-filled part rubs against a metal surface or even a similar glass-filled surface, rapid abrasion takes place," says George Osterhout, v.p. of Dimension Bond, a Chicago-based supplier of a specialized coating service that can address this problem."The reason for the abrasion is minute ends of the fiber reinforcing materials protruding from the surface of the filled part," adds Osterhout.

Automated Assembly Integrates Leak Testing For Lower Cost, Higher Output
