Steel forgings improve the internal structure and mechanical properties of the forgings during the forging process. Therefore, forgings have high mechanical strength, are not easy to break, and improve toughness. They are generally used in parts that require large stress, or parts with harsh working environments, such as gears or engine shafts. In addition to improving mechanical properties, forging has the advantages of high utilization of materials and high productivity. For some parts that require precision assembly or high precision, it can be achieved by secondary precision CNC machining. However, due to the characteristics of the forging process, forging is not suitable for the production of workpieces with complex shapes, or requires a relatively large amount of subsequent CNC machining to achieve products with complex shapes.
For forged parts, the most important are the three processes of mold development, forging processing and secondary precision CNC processing. And these three processes are all completed in-house, we can better ensure product quality and production delivery. We take quality first and service first for our customers.
