The Processing Method Of The Screw:
Turning: The material is made to the desired shape by removing the material. Advantages: high machining accuracy, no mold restrictions. Disadvantages: high production cost and slow processing speed.
Forging: Extrusion of material by external force to deform it to achieve the desired shape. Advantages: fast production speed, low cost, suitable for mass production. Disadvantages: The forming is limited by the mold, and the cost of the mold for complex products is high.
Cold heading: It is the process of extruding and deforming the metal wire with the help of external force when the metal wire is not heated. The cold heading process is only one of the forging processes.
