Fully Automatic Small U-bolt Production Line – Low Scrap Rate
Feature:
- Ultra-low Scrap Rate
Optimized bending and thread forming mechanism minimizes deformation/scratches, controlling scrap rate below 0.2% for small workpieces.
- Durable Alloy Core Components
Key parts (bending dies, thread rolling wheels) made of Cr12MoV alloy steel, service life over 8 years, 50% lower wear rate.
- Multi-material Compatibility
Suitable for carbon steel, stainless steel, copper, and galvanized wire, meeting small U-bolt needs in electronics, automotive, and hardware industries.
- Quiet & Low-vibration Operation
Built-in shock absorption system and precision transmission structure, operating noise ≤70dB, complying with workshop environmental standards.
