Polyurethane is a specification molder of castable polyurethanes. Polyurethane molders open by methods such as compression, transfer, pressure and centrifugal cast molding. A wide range of this product are available in various specifications.

rod wiper/scrapers effectively wipe and scrape the full 360º circumference of a reciprocating rod. They are designed to remove road dust, dirt, ice, mud, weld flash, paint and many other particulates from the rod surface.

They prevent damage to bearings, seals, packings, and rods, thereby reducing or eliminating contamination of fluids in hydraulic systems.

Rod wiper/scrapers consist of a honed, doublespiral, wiping element of age-hardened beryllium copper (Rockwell C 40 hardness) surrounded by a synthetic rubber elastomer. It is designed so that the beryllium copper element is distended from the final rod diameter.It is precision honed to an inner-diameter tolerance of+/- 0.0005". The honing process guarantees a true circle on the ring inside diameter and provides a highly polished and knife sharp edge. In operation, the beryllium copper ring polishes the rod without damage to the rod's finish. It is self-sharpening and does not oval, curve, or feather.

Rod wiper/scrapers are found wherever hydraulic or pneumatic cylinders are used. They have demonstrated their effectiveness on fork lifts, resistance welders, off-road machinery, farm equipment, hydraulic presses, foundry machines, and aircraft landing gear.
