Operating Points

Before starting the machine

  1. Before the operation of the injection molding machine, check whether there is water or oil in the electrical control box, and do not start the machine if the electrical appliances are damp. There should be maintenance personnel to blow dry the electrical parts before starting the machine.
  2. Before the operation of the injection molding machine, check whether the power supply voltage is in line with the general should not exceed ± 6%.

Operation of injection molding machine

  1. Check whether the emergency stop switch, front and rear safety door switches are normal. Verify whether the rotation direction of motor and oil pump is the same.
  2. Check whether the cooling pipes are long distance and smooth, and pass cooling water to the oil cooler and the cooling water jacket at the end of the barrel.
  3. Before the operation of the injection molding machine, check whether there is lubricating oil in each movable part, and add enough lubricating oil.

6.Turn on the electric heat and heat each section of the barrel. When the temperature of each section to meet the requirements, and then hold a period of time in order to stabilize the temperature of the machine. Holding time varies according to the requirements of different equipment and plastic raw materials.

  1. Add enough plastic in the hopper. According to the requirements of injection molding of different plastics, some raw materials are best to be dried first.
  2. Cover the heat shield on the barrel of the machine, which can save electricity and extend the life of the electric heating ring and current contactor [1]. As shown in the figure “Operation of Injection Molding Machine”.
