cold forging , warm forging process , our in forging based.

By forging metal intrinsic defects can be eliminated to improve the metal structure , a reasonable distribution of the metal flow lines , metal tightness is good. Forging process is widely used in bearings molding , you can complete from the small diameter of ~ 20mm diameter 5000mm oversize product to product processing . Forging common methods are: hot forging , cold forging , warm forging process , our in forging based.
Hot forging molding processing equipment for its further divided into : free forging process , press forging process , flat forging machine forging process and high-speed Upsetters forging process .
Ferrule forming methods
Currently in ferrule machining, molding methods are mainly the following: lysn-bearing  turning forming, cold forming and cold rolling (temperature) extrusion molding. In the above molding method, forging forming the most widely used, accounting for about 80% of production volume, for some small generic products can be used rod (tube) feeding directly Turning molding. Since the 1980s, China's small and medium enterprises in the production of small and medium sized rings using a cold rolling and cold (warm) extrusion molding process.
