Fasteners & Precision Components
Fasteners Surface Treatment in India for High-Performance Precision Components
Fasteners and precision components demand uniform coatings, tight tolerance control, and long-term corrosion resistance. Suntech delivers fasteners surface treatment in India using advanced electroplating, electropolishing, passivation, and de-embrittlement solutions. Our automated systems are engineered for safety-critical fasteners and precision-engineered components requiring durability, strength, and fatigue resistance.
Our Solution for Fasteners & Precision Components
Chemical Surface Treatment Lines
Main Use Areas:
- Degreasing, pickling & phosphating of bolts, screws, shafts
- Activation for plating adhesion and torque enhancement via phosphating
1. Electroplating
Key Parts:
➤ Screws, studs, washers – Zinc/Zinc-nickel coatings
➤ Micro parts –Thin, uniform plating with tight tolerances
2. Electropolishing
Key Parts:
➤ Precision shafts, surgical screws, springs – Enhanced fit and finish
3. Passivation
Key Parts:
➤ Machined stainless parts – Long-term corrosion protection without adding coating
4. De-Embrittlement & Hydrogen Relief Lines
Used On:
- ➤ Post-hardened fasteners – Safety-critical components
