How to use the screw barrel of the injection molding machine correctly:
 The injection screw and barrel work under high temperature, high pressure, high mechanical torque and high friction environment for a long time. The first few factors are required by the process conditions, and the loss caused by friction is inevitable. Generally, the screw and barrel have undergone surface nitriding treatment to improve the surface hardness, that is, to improve the wear resistance.
   1. Every plastic has an ideal plasticizing processing temperature range, and the processing temperature of the barrel should be controlled to make it close to this temperature range.
  2, the speed should be adjusted properly. The speed should be moderate and not too high.
   3. To check out the debris in the plastic. Sundries will affect the service life of the screw barrel of the injection molding machine, and it is also detrimental to the processing.
  4. The screw barrel of the injection molding machine should be dried before injection molding to prevent moisture, which will wear the screw barrel to a certain extent and affect the life of the screw barrel.
