The second-hand injection molding machine occupies a high share of the current injection molding machine market. This is also related to the development needs of the times. However, there are many details about the use of second-hand injection molding machines. What should I pay attention to before using a second-hand injection molding machine?

1. Before operating the second-hand injection molding machine, check whether water or oil enters the electrical control box. If the electrical appliance is damp, do not turn it on. Maintenance staff should blow-dry the electrical parts before turning on the machine.
2. Check whether the emergency stop switch and the front and rear safety door switches are normal. Verify that the electric idea and the rolling direction of the oil pump are consistent.

3. Before operating the second-hand injection molding machine, check whether there is lubricating oil in each flow part, and add enough lubricating oil.
4. Before operating the second-hand injection molding machine, check whether the power supply voltage fits. Generally, it should not exceed ±6%.
5. Check whether the cooling pipes are being dredged for long distances, and pass cooling water to the oil cooler and the cooling water jacket at the end of the barrel.
6. Cover the heat shield on the barrel, which can save power and extend the life of the heating coil and current contactor.
7. 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 keep the mechanical temperature stable. The heat preservation time varies according to the requirements of different equipment and plastic materials.
8. Add content plastic in the hopper. According to the requirements of different plastics for injection molding, some materials pass through the dry first.
