The quality of the expansion machine product is good. The metal fibers of the rolled ring are continuously distributed along the circumferential direction, which is adapted to the stress and wear of the parts during use. In most cases, the internal structure of rolled rings is dense and the grain size is small, and the comprehensive mechanical properties are significantly higher than those of rings processed by other methods. Low production cost. Compared with free forging, it has lower material consumption, lower energy consumption, lower overall production costs, and better economic benefits. Lie: Many new and old customers come to purchase.
