Door and window pulley processing technology

  The machining process of door and window pulleys varies depending on the material. 

  Generally speaking, the processing of pulleys includes the following steps: firstly, select suitable materials according to the design requirements, and then process them through stamping, turning, milling and other processes. In the processing, attention needs to be paid to details such as the size, shape and position of the pulley to ensure that it meets the design requirements. 

  Finally, the surface treatment of the pulley, such as spraying, galvanising, etc., to improve its corrosion resistance and aesthetics .
