There are three ways to process screws:
1. Turning (Turning)
Make the material reach the desired shape by removing the material
Advantages: high processing accuracy, no mold restrictions
Disadvantages: high production cost, slow processing speed
2. forging (Forging)
Squeeze the material by external force to deform it to achieve the desired shape
Advantages: fast production speed, low cost, suitable for mass production
Insufficiency: Molding is limited by molds, and mold costs for complex products are high
3. Cold heading
Cold heading is a process in which the metal wire is extruded and deformed with the help of external force when the metal wire is not heated. The cold heading process is a kind of forging process.
