- Available in cold-rolled steel, stainless steel, aluminum, and copper
This product exemplifies our approach to stamping component design – combining functionality, durability, and ease of use while minimizing the need for secondary operations.
2. CNC Machined Components
Our CNC machining capabilities produce components with micron-level precision. The brass connecting rod represents our expertise in this area, featuring:
- One-piece molded construction for precise dimensions
- Smooth surface finish without burrs
- Excellent electrical and thermal conductivity
- Corrosion-resistant brass material
- Customizable in phosphor copper, red copper, aluminum, and iron
This component is widely used in connectors, automotive parts, new energy equipment, medical instruments, and electrical terminals, demonstrating the versatility of our CNC machining services.
3. Precision Knurled Galvanized Sleeve (Metal Bushing)
As a prime example of our non-standard custom hardware production, this component features:
- Numerically controlled one-piece turning
- Smooth tube wall with precise dimensions
- Middle knurling design for enhanced assembly friction
- Galvanized anti-rust treatment for long service life
- Customizable in iron, stainless steel, brass, and aluminum
