2. Check whether the supply voltage meets, generally should not exceed ±6%.
3. Check the emergency stop switch, before and after the safety gate switch is normal. Verify that the motor and oil pump are in the same direction of rotation.
4. Check whether each cooling pipe is unimpeded for a long distance and pass cooling water into the oil cooler and the cooling water jacket at the end of the barrel.
5. Check for grease on all moving parts and add enough oil.
6. Turn on the heat and heat each section of the barrel. When the temperature of each section reaches the required temperature, it is kept 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.
7. Add enough plastic in the hopper. According to the requirements of injection molding different plastics, some raw materials are best dried.
8. To cover the heat shield on the barrel, this can save energy, but also can extend the life of the electric ring and contactor.
Injection molding machine operation
1. Do not arbitrarily cancel the role of the security door for the sake of convenience.
2. Observe the temperature of the pressure oil and do not exceed the specified temperature. The ideal working temperature of hydraulic oil should be kept between 45-50°C, and it is generally suitable in the range of 35-60°C.
3. Pay attention to adjust each stroke switch to avoid impact when the machine moves
At the end of the injection molding machine work
1. Before shutdown. The plastic in the barrel should be cleaned to prevent oxidation of leftovers or long-term thermal decomposition.
2. The mold should be opened so that the toggle mechanism time is locked.
3. The workshop must be equipped with lifting equipment. Care should be taken when mounting and disassembling the mold to ensure production safety.
