Product Description
Hydraulic chrome-plated rod is a cylindrical steel component used in hydraulic systems. It is typically made from high-quality steel that undergoes hardening and is coated with a layer of chromium. The chrome coating provides a smooth, durable surface resistant to corrosion, while the steel core ensures strength and durability. Hydraulic chrome-plated rods are commonly used in hydraulic cylinders-devices that use pressure to move loads. They offer a reliable, efficient means of transferring force between hydraulic systems and mechanical components. Common applications include the automotive industry, construction equipment, and manufacturing machinery.
Quality Control and Inspection
To ensure the quality of each piston rod, the production process requires rigorous inspection:
1. Dimensional Accuracy Inspection: Using micrometers, calipers, and CMM coordinate measuring machines.
2. Surface Quality Inspection: Visually inspecting the surface for defects using a magnifying glass; checking surface roughness with a roughness tester.
3. Hardness Testing: Using Vickers or Rockwell hardness testers to test the hardness of the coating and substrate.
4. Coating Thickness Inspection: Using eddy current thickness gauges or metallographic methods.
5. Adhesion Testing: Regularly conducting bending tests or thermal shock tests.
6. Corrosion Resistance Testing: Salt spray testing to evaluate its corrosion resistance.
Production Process Flow
The manufacturing process follows a strict multi-step process: raw material selection → cold drawing/turning → centerless grinding → precision polishing → induction hardening (optional) → hard chrome plating → final polishing → quality inspection → protective packaging.
