Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, which is a foreign trade oriented economic developed city, adjacent to international port city Shanghai. Established in 2009, we're a manufacturing company specialized in the production of piston rods and linear shafts.
     Quality  is  Life  of  Enterprise. Your  Satisfaction  is  Our  Goal.      Â
Â
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.

BRIGHT STEEL BAR
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty
