Our piston rod can be directly used for hydraulic cylinder, air cylinder and shock absorber. We have introduced advanced precise cold drawing and high precision polishing for the production. Every parameter of our hydraulic cylinder parts is up to the national standards.
The piston rod is widely used for textile printing and dyeing, printing machine's guiding rails, die casting machine, ejection molding machine's rails and ejector pin, and the guide pillar of the four-pillar type hydraulic cylinder.
According to the applications, we choose suitable carbon steel or alloy steel for this cylinder rod. On the basis of high performance heat treatment, we have introduced hard chrome plating and nickel plating techniques, and high speed polishing treatment. The surface smoothness and anti-corrosion performance are enhanced. Then the service life of the piston rod is extended.Parameter
