Minnesota Rubber Floating Pistons

By Patrick Curran | July 1, 2010

Minneapolis, MN – Motor vehicle designers requiring custom molded high performance plastic (HPP) components such as floating pistons for shock absorbers benefit from Minnesota Rubber and Plastics (MR&P) capabilities.

Minnesota-Rubber-Floating-Piston

Molded of HPP resin material, these 1-3/4 inch diameter floating pistons feature a special Quad Ring® seal that fits securely inside the shock absorber bore. The seal separates the gas-charged portion of the bore from the oil portion, sliding up and down smoothly and efficiently when in operation.

Precision molded of a glass filled, specially formulated, heat stabilized Nylon compound, the piston body is designed with a 1/8 inch groove to hold the Quad-Ring® seal securely in position so that no twisting of the seal occurs during operation. The seal is precision molded from a specially formulated HNBR elastomer designed for high concentricity, low friction, and long operating life.

To facilitate manufacture, a high speed automated system moves the injection molded pistons into position for assembly with the Quad-Ring seals. During assembly, a small amount of silicone lubricant is automatically applied to the seal. Once assembled, the system’s vision system inspects for quality, ensuring that seals are positioned correctly within piston slots. The automated system operates 24/7 with output capacity in the millions per year.
