Product Description

     Quality  is  Life  of  Enterprise. Your  Satisfaction  is  Our  Goal.       
Main Products:

We offer the manufacturers of hydraulic and pneumatic cylinders a wide assortment of high quality tube and piston products.

Hard Chrome Plated Rod, Hydraulic Piston Rod, Cylinder Piston Rod, Chromium Rods, Hard Chrome Shaft, Induction Rod, Induction Shaft, etc.

Material: JIS S45C, SAE1045, DIN CK45

The hard chromium piston rods produced by our company come with more than JIS S45C material, where the rods first undergo precision milling and processing, and are then put through gard surface chromium treatment, allowing a surface precision level of f7, and a surface hardness reaching HV800 minimum and up, which not only help to improve wear resistance but also help to extend the life cycle of the rods, thus helping the customer save cost.

The corrosion resistances is tested in our own internal salt spray laboratory, and The rods surface heat treatment and hardness reaching HRC55°±2°, and at a hardened depth of between 0.5mm - 3mm, before the rods are put through precision milling and hard chromium treatment for a membrane thickness measuring 20 micron ± 10% to drastically improve the rod's wear resistance, and help to extend the life cycle of the rods.

The furnished products are ideal for a host of heavy machinery, construction equipment, and as position mount for a variety of heavy equipment.

Suzhou Weipeng products such as chromed steel bars and tubes are used in the fabrication of hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, product handling equipment, garbage collection, heavy equipment, and many other applications.

Chrome Plated Steel Bars:

Our Chrome Plated Bars are produced from medium carbon cold-finished or hot rolled steel bars usually in 1045 grades. The bars are centerless ground, polished, and chrome plated to a minimum thickness of 0.0005", and 0.001" per side. 
Chrome Plated bars are specifically designed to be used for most piston rod applications in hydraulic and pneumatic cylinders.

Induction Hardened Chrome Plated Bars:

Our  Induction Hardened Chrome Plated Bars are produced by using advanced processing techniques usually on JIS S45C, SAE1045 or DIN CK45 steel rods, for surface removal, polishing, induction hardening, followed by hard chrome plating to a thickness minimum of 0.0005" or 0.001" per side. The finished product results in a superior impact resistant bar ideal for high quality piston rods capable of handling tough environments.

Cold Drawn Seamless Mechanical Tubing (CDS)

is a cold drawn 1020 steel tube. Produced from piercing hot rolled bar stock, the cold drawing process increases the tube's physical properties reducing the cost of machine time. Cold drawn seamless tubing provides a better uniformed OD and ID, enhanced machinability, increased strength, and tighter tolerances compared to hot finish seamless products
