The forging tooth forming hydraulic press is the core machine in the forging tooth production process. By applying external force to the metal raw materials using this press, it causes plastic deformation of the metal, changing the shape and size of the billet while improving its internal structure and mechanical properties, resulting in the final formed forging tooth. Forging eliminates defects such as porosity generated during the metal smelting process, optimizes the microstructure, and since it preserves the complete metal flow line, the mechanical properties of forgings are generally superior to castings made from the same material. Therefore, although the forging tooth production process is costlier, it ensures the highest quality for the forged teeth. The forging tooth is a crucial component on excavators, similar to human teeth, and is an easily worn part, requiring continuous production and processing to meet demand.
