| 9 | Center elevation | 1000mm |
| 10 | Production method | Continuous production |
| 11 | Finished products | 1) Spring wires produced by this production line would keep uniform and straight; 2) Products keep consistence with EN10270-2:2011, tensile strength fluctuation of the same coil of spring wire would be ≤50MPa |
III. Fetures
1. Automatically connect the spring manipulator to catch the spring when retracting and move to the next station.
2. The material is automatically clamped and loosened, and the spring is automatically retracted. The winding process is fully automatic.
3. The reducer uses servo-specific reducer, which has large torque, high transmission efficiency, no oiling and no maintenance for life.
4. High cost performance, high speed and high efficiency, and durable automatic/manual lubrication, easy maintenance.
