Small U Bolt Manufacturing Machine Durable Low Maintenance Φ3-Φ12mm U Bolt Maker
High precision U bolt machine with ±0.05mm tolerance and ±0.5° bending accuracy. Covers Φ3-Φ12mm diameters, 20-100mm lengths. One-person operation replaces 3-4 workers, cutting labor costs by 60%. Wear-resistant alloy components ensure long-term stability. Ideal for small-batch, multi-variety orders.
High Precision & Stable Quality for Small Parts
±0.05mm dimensional tolerance and ±0.5° bending accuracy ensure consistent quality of small U-bolts; ultra-low scrap rate minimizes raw material waste.
Flexible Production & Fast Order Response
Covers Φ3–Φ12mm diameters and 20–100mm lengths; 8-minute mold changeover adapts to small-batch, multi-variety orders, improving market responsiveness.
Full Automation & Labor Cost Reduction
One-person operation replaces 3–4 manual workers, cutting labor costs by 60%; intelligent touch screen operation requires no professional skills.
Durable & Easy Integration
Wear-resistant alloy components ensure long-term stable operation; standardized interfaces enable seamless integration into small-scale automated lines, supporting capacity expansion without extra space.
