1it is an advanced forming process, suitable for high precision forming mufti-shoulder shafts. 2the productivity is twice to five times of traditional die forging. The material usage is high, because of no flash. So the die lifetime is prolonged at least 10 times than used in other traditional machinery. 3t is with high deforming precision, and the material volume distribution is accurate and stable. 4the double eccentric adjusting mechanism for center distance is patent technology. 5t has outstanding advantages, such as high-rigidity, high automation degree and convenient for integrating the whole production line. 6dismantling roller, continuous heating, adjustable revolving speed, center distance adjusting, etc. Are all available. 7friendly working environment can improve the working condition; no shocking and low noise in the operation of rolling, which meet the environmental requirements of modern manufacturing. 8we can provide process, dies designing and manufacturing. And it can be matched with heating furnace to be automatic rolling lines.
