Surface Treatment
To enhance durability and performance, we offer various surface treatments for our products:
- Anodizing for aluminum components
- Nitriding for increased wear resistance
- DLC (Diamond-Like Carbon) coating for reduced friction
- Phosphate coating for corrosion protection
- Electroplating (chrome, nickel, zinc) for improved aesthetics and wear resistance
Our engineering team can recommend the most suitable surface treatment based on your specific application and operating conditions.

Drawing Guide
We work closely with our clients to bring their designs to life. To ensure a smooth production process, please provide the following when submitting your custom engine part drawings:
