High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. HDPE is commonly recycled, and has the number "2" as its resin identification code.It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber.

**Company Overview**
Suzhou Weipeng Precision Machinery Co., Ltd. is located in Suzhou, a city known for its strong foreign trade and proximity to Shanghai, one of the world’s major ports. Established in 2009, we are a manufacturer specializing in the production of piston rods and linear shafts. Our commitment to quality is at the core of our business, and your satisfaction is our ultimate goal.
**Main Products:**
We provide manufacturers of hydraulic and pneumatic cylinders with a wide range of high-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
**Materials Used:**
JIS S45C, SAE1045, DIN CK45
Our hard chrome piston rods are manufactured using advanced techniques. After precision milling, they undergo surface chromium treatment, achieving a surface precision level of **f7** and a minimum hardness of **HV800**, significantly enhancing wear resistance and extending the life of the rods. This helps our customers reduce long-term costs.
Our corrosion resistance tests are conducted in an internal salt spray laboratory. The surface heat treatment ensures a hardness of **HRC55° ± 2°**, with a hardened depth ranging from **0.5mm to 3mm**. The chrome layer thickness is typically **20 microns ± 10%**, further improving wear resistance and service life.
These rods are ideal for use in heavy machinery, construction equipment, and as positioning components for various heavy-duty applications. Our chromed steel bars and tubes are widely used in agricultural machinery, lifting equipment, material handling systems, waste collection, and other industrial sectors.

**Chrome Plated Steel Bars:**
Our chrome-plated bars are made from medium carbon cold-finished or hot-rolled steel, typically grade 1045. They are centerless ground, polished, and chrome-plated to a minimum thickness of 0.0005" per side. These bars are ideal for most piston rod applications in hydraulic and pneumatic cylinders.
**Induction Hardened Chrome Plated Bars:**
Produced using advanced techniques on JIS S45C, SAE1045, or DIN CK45 steel rods, these bars go through surface removal, polishing, induction hardening, and hard chrome plating. The result is a durable bar suitable for high-performance piston rods in demanding 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 and Shipbuilding Industries
**Honed Tubes:**
