writer:LI SONG Share

With the continuous development of the injection molding industry, the market demand for high-speed injection molding machines is also increasing. Here, Lisong Machinery will introduce you to the correct opening method for high-speed injection molding machines.

The process of the correct opening method of the high-speed injection molding machine:
1. Turn on the electric heater to heat each section of the barrel. When the temperature of each section reaches the requirements, keep it warm for a period of time to stabilize the temperature of the machine. The holding time varies according to the requirements of different equipment and plastic materials.
2. Check whether the emergency stop switch injection molding machine and the front and rear safety door switches are normal. Verify that the rotation direction of the motor and the oil pump are the same.

3. Add enough plastic in the hopper. According to the requirements of different plastics for injection molding, some raw materials are best to be dried first.
4. Before the operation of the injection molding machine, check whether the power supply voltage conforms to it. Generally, it should not exceed ±60%.
5. Cover the heat shield on the barrel, so as to save energy and extend the life of the electric heating coil and current contactor.
6. Before operation of the injection molding machine, check whether there is lubricating oil in each movable part and add enough lubricating oil.
7. Before operating the injection molding machine, check whether there is water or oil in the electrical control box. If the electrical appliance is damp, do not turn it on. There should be maintenance personnel to dry the electrical parts before starting the machine.
8. Check whether the cooling pipelines are unblocked for a long distance, and pass cooling water into the oil cooler and the cooling water jacket at the end of the barrel.

After achieving the above 8 points, you can master the use of high-speed injection molding machines, and at the same time, you can increase the service life of injection molding machines!
