The common processing techniques for hardware tools include the following:
- Forging
According to whether the forging billet is heated, it can be divided into two types: cold forging and hot forging.
Cold forging is the process of stamping and forming raw materials at room temperature without heating, requiring high technical expertise.
Hot forging is a low-cost process where the processed billet is heated to a certain temperature and then stamped into shape.
After heating, metal materials will change their original grain structure, and the material will undergo thermal expansion and contraction after heating, making it difficult to achieve the design accuracy of the formed size. So generally speaking, cold forging is superior to hot forging. - Heat treatment
The heat treatment of steel is the process of heating it to a certain temperature in a solid state, providing necessary insulation, and cooling it to room temperature at an appropriate rate to change the internal structure of the steel and obtain the desired properties. - Surface treatment
- Electroplating
- Sandblasting
- Phosphating
- Polishing
