Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene. It was the first grade of polyethylene, produced in 1933 by Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. Its manufacture employs the same method today. Low Density Polyethylene (LDPE): It`s the industry workhorse. Used in applications as diverse as liners and food storage bags to shrink and collation films. Offering options for flexible packaging, caps and closures, plastic toys.

Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, a city known for its strong economic development and proximity to the international port of Shanghai. Established in 2009, we specialize in manufacturing high-quality piston rods and linear shafts for hydraulic and pneumatic systems.
Quality is the lifeblood of our company. Your satisfaction is our ultimate goal.
Main Products:
We provide manufacturers of hydraulic and pneumatic cylinders with a wide range of premium-quality tube and piston products, including:
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 are made from more than just JIS S45C material. They undergo precision milling and processing before undergoing a surface chrome treatment that achieves a surface precision level of f7, with a minimum hardness of HV800. This not only enhances wear resistance but also extends the service life of the rods, helping customers reduce long-term costs.
Our corrosion resistance testing is conducted in an in-house salt spray laboratory. The rods undergo surface heat treatment, reaching a hardness of HRC55°±2° with a hardened depth between 0.5mm – 3mm. After this, they go through precision milling and hard chrome plating, with a coating thickness of 20 microns ±10%, significantly improving wear resistance and extending the rod's lifespan.
These products are ideal for use in heavy machinery, construction equipment, and various heavy-duty positioning systems.
Suzhou Weipeng’s chromed steel bars and tubes are widely used in the fabrication of hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, material handling systems, waste collection, and other industrial applications.

Chrome Plated Steel Bars:
Our Chrome Plated Bars are made from medium carbon cold-finished or hot rolled steel bars, typically in 1045 grades. These bars are centerless ground, polished, and chrome plated to a minimum thickness of 0.0005", with 0.001" per side. They are specifically designed for most piston rod applications in hydraulic and pneumatic cylinders.
Induction Hardened Chrome Plated Bars:
Our Induction Hardened Chrome Plated Bars are produced using advanced techniques on JIS S45C, SAE1045, or DIN CK45 steel rods. The process includes surface removal, polishing, induction hardening, and hard chrome plating to a thickness of at least 0.0005" or 0.001" per side. The result is a highly impact-resistant bar suitable for high-quality piston rods capable of withstanding tough environments.
Applications:
Linear Motion Guides, Hydraulic Cylinder Rods, Plastic Injection Molding Machines, Construction Equipment, Rubber Molding Machines, Papermaking Machines, Printing Machines, Refrigeration Equipment, Food and Chemical Machinery, Loading Equipment, Fiber Spinning Equipment, Textile Machinery, Agricultural Equipment, Automotive, Shipbuilding, and More.

Cold Drawn Seamless Mechanical Tubing (CDS)
is a cold-drawn 1020 steel tube. It is manufactured from pierced hot-rolled bar stock, and the cold drawing process improves the physical properties while reducing machining time. Cold-drawn seamless tubing offers better OD and ID uniformity, improved machinability, increased strength, and tighter tolerances compared to hot-finished seamless products.
Applications:
Hydraulic Cylinders, Truck and Automotive Parts, Heavy Equipment, Agricultural Components, Auto and Truck Axles, Suspension Parts and Shock Absorbers, High-Speed Shafts and Rollers, Bearings and Spacers, Roll Cages, and Many Other Machined Tubular Parts.
We use the most renowned brands in China as raw materials, ensuring high density and consistent quality. Our products are well-received by clients due to their competitive pricing and excellent performance.
Wishing You a Happy New Year.
