**Company Overview**
Suzhou Weipeng Precision Machinery Co., Ltd. is based 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 specialize in manufacturing high-quality piston rods and linear shafts. Our commitment to quality is reflected in every product we produce.
**Quality is Life of Enterprise. Your Satisfaction is Our Goal.**
Our main products include:
- Hard Chrome Plated Rod
- Hydraulic Piston Rod
- Cylinder Piston Rod
- Chromium Rods
- Hard Chrome Shaft
- Induction Rod
- Induction Shaft
We use materials such as JIS S45C, SAE1045, and DIN CK45 to ensure superior performance and durability. Our hard chromium piston rods are processed with precision milling and surface chromium treatment, achieving a surface precision level of **F7** and a hardness of **HV800 minimum**. This enhances wear resistance and extends the service life of the rods, helping our customers reduce long-term costs.
Our corrosion resistance tests are conducted in an internal salt spray laboratory. The rods undergo surface heat treatment, reaching a hardness of **HRC55°±2°**, with a **hardened depth of 0.5–3mm**. After precision milling and hard chrome plating, the membrane thickness reaches **20 microns ±10%**, significantly improving wear resistance and extending the rod's lifespan.
These products are ideal for heavy machinery, construction equipment, and various industrial applications. They are widely used in hydraulic and pneumatic cylinders found in agricultural machinery, lifting equipment, handling systems, garbage collection, and more.

**Chrome Plated Steel Bars**
Our chrome-plated bars are made from medium carbon cold-finished or hot-rolled steel, typically grade 1045. These are centerless ground, polished, and chrome-plated to a minimum thickness of 0.0005" on each side. They are designed for use in 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 then hard chrome plating. The result is a durable, impact-resistant bar suitable for high-performance piston rods.
**Applications**
- Hydraulic cylinder rods
- Farm equipment machinery
- Pin stock for attachments
