HD500Piston Pin
Reasons for the Failure of Piston Pins
Hazards: Piston pin failure is one of the common faults in engines, which may lead to abnormal noise, power reduction and even severe mechanical damage.
Failure causes: Poor lubrication, material or manufacturing defects, improper assembly, overload or shock load, fatigue failure, corrosion and wear, design or matching issues, improper maintenance.

Advantages of DLC Coating on Piston Pins
| Main advantages | |
| Production | DLC is highly hard and wear-resistant, preventing the friction and wear of piston pins, increasing their lifespan by 2 to 3 times or more, and significantly reducing the risk of piston pin failure due to abrasive wear. |
| 2. The DLC film layer is uniform and smooth, which not only does not affect the concentricity of the product but also plays a lubricating role, greatly extending the service life of the piston pin. | |
| 3. The DLC coating has certain corrosion resistance and can effectively enhance the chemical corrosion resistance of the piston pin. | |
| Productivity | 1. Large furnace loading capacity, high coating uniformity and short coating time |
| 2. The lifespan is increased by more than 2 to 3 times | |
| Terminal product | 1. Significantly increase the lifespan of piston and engine terminal products |
| 2. Reduce the frequency of return repairs for terminal products |
