The manufacturing process begins by pouring molten metal into a mold cavity with a repeating tooth pattern. After cooling, remove the tooth from the mold.
The casting process can cause air to become trapped during metal pouring, and excess metal can be created when the two parts of the mold are joined together. The mechanical properties and wear resistance of cast teeth are not as good as forged teeth.
Forged teeth are made from blanks through an innovative forging process. Forging presses are used to generate extreme pressure and high temperature extrusion to optimize the grain flow of steel to provide enhanced mechanical properties. Forged teeth have high impact strength, better wear resistance and longer service life.
