2）HOT-COLD COMPOUND PRECISION FORGING TECHNOLOGY
By Using hot-cold composite precision forging process technology, the forgings can be obtained close to the dimensional accuracy and surface quality of cold forging, and at the same time, the process can be reduced and the forming force can be reduced.
