quality and improve producing efficiency, we have bought the modern
producing line instead of handwork.Firstly, it can improve the
producing capability. What's more, can reduce the employee's
workload.>>>Quality Test & Control:We have the complete
quality control system. The control is from raw material, producing
process to the finished product.And the quality control include the
chemical composition, mechanical load, metallographic analysis,
detection of defects, dimension.Test Machines:>>>Exported
