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.

Our hard chrome piston rods are manufactured using high-quality JIS S45C steel. The process begins with precision machining, followed by surface chromium treatment, achieving a surface finish of **f7** and a hardness of **Hv800 minimum**. This ensures excellent wear resistance and extends the lifespan of the rods, helping our customers reduce maintenance costs.
The corrosion resistance is tested in our internal salt spray laboratory. The surface undergoes heat treatment to reach **HRC55°±2°**, with a hardened depth ranging from **0.5mm to 3mm**. After that, the rods go through precision milling and hard chrome plating, with a coating thickness of **20 microns ±10%**, significantly improving wear resistance and durability.
We offer two main types of chrome-plated rods:
1. Chrome Plated Steel Bars:
Made from medium carbon cold-finished or hot-rolled steel bars (usually 1045 grade), these are centerless ground, polished, and chrome-plated to a minimum thickness of 0.0005", with 0.001" per side. They are ideal for use in hydraulic and pneumatic cylinders.
2. Induction Hardened Chrome Plated Bars:
Produced using advanced techniques on materials like JIS S45C, SAE1045, or DIN CK45. These rods are polished, induction-hardened, and then chrome-plated to a minimum of 0.0005" or 0.001" per side. The result is a strong, impact-resistant bar suitable for harsh environments.
Our products are widely used in applications such as:
- Linear motion guides
- Hydraulic cylinder rods
- Plastic injection molding machines
- Construction equipment
- Papermaking machines
- Refrigeration systems
- Food and chemical machinery
- Agricultural equipment
- Automotive and shipbuilding
