Hard Chrome Plated Piston Rod & Induction Hardened Bar Manufacturer
As a professional manufacturer with over 17 years of experience, we specialize in producing high-precision hard chrome plated piston rods, induction hardened chrome bars, and nickel-chrome plating bars. Our products are widely used in hydraulic cylinders, pneumatic systems, and industrial machinery globally.
Why Choose Our Chrome Plated Piston Rods?
Our piston rods are manufactured through a rigorous multi-step process, including hot rolling, peeling, induction hardening (optional), surface grinding, and hard chrome plating. With more than ten precision processes, we ensure ISO f7 diameter tolerance and excellent surface quality.
