Including free forging

　　We are specialized in producing flanges, Such as weld neck flanges, Slip on flanges, Blind flanges, Socket flanges, threaded flanges and plate flanges etc. We have ability to produce you the detailed drawing flanges also. We have been in this line for over 25 years. Our products are exported to many countries and regions, such as Southeast Asia, the Middle East, Europe and America etc. We have a good reputation in domestic and foreign markets.

　　Including free forging, the forging, flange processing materials from the mold surface near to the free surface expansion. Therefore, difficult to guarantee the accuracy, so will die of the direction of motion and rotary forging process by computer control, can lower the forging force obtained with complicated shape and high precision products. For example, the production of many varieties, large size of the turbine blade forging. Flat welding flange forging can be divided into free forging, upsetting, extrusion, forging, closed die forging, closed upsetting. Generally speaking, in the temperature region where there is recrystallization, the forging is called hot forging, which is not heated at room temperature. Flange in cold forging, the forging of the size changed little. In 700 DEG forging, oxide formation, and surface decarburization.
