Do you know how to operate injection machine and what you should pay attention in injection machine operation? How to adjust the parameter for injection mould? We are injection machine and plastic mould manufacture; following list some attention points for injection machine operation.

1. Connected power and make sure the water, power, and air working correctly.

2. Start autoloader and dryer; check the hot runner system, make sure all the connector is correct, then open the cooling water and hot runner system.

3. Open the main power; check the heating system, power supply.

4. Heating the injection machine (heating ring), make sure the temperature is correct for the product.

5. Check the oil tank and lubricating oil, make sure injection machine oil is adequate.

6. Start the injection machine; check if the motor and pump working well. If there any problem, start the motor after exclude the problem. Machine Hydraulic system need the oil temperature higher than 30℃.

7. Lubricate the injection machine, for clamping system and other moving parts.

8. Opening the mould by manual, clear the mould, and make sure the mould cavity and core is in good condition; check the mould actions, such as sliders, ejector pin, or oil cylinders.

9. Lubricate the mould moving parts. After clean and lubrication, make sure the slider or other moving parts in the correct position (the same as the mould open).

10. Checking the stroke switch and safety device of injection machine.

11. Make sure molding parameter is suitable for the production.

12. Use low pressure and low speed to check the mould action (open and close mould, push and return the ejector pin, oil cylinders action, and injection unit moving), make sure above action is work smoothly. When you moving the injection unit, make sure the mould is closed.

13. After injection machine temperature is reach to set value, keep this temperature for 10-30mins, and then make plasticizing and injection. (when you test the plasticizing and injection, use 30% pressure and speed of set value, use inching )

14. Running the injection machine and mould by manual or semi-automatic for 10-20 shots. Check the mould and machine condition. If all themachine operation is working well, then make production automatically.

15. At beginning of production, review the product and machine working condition, pay attention to the temperature for mould and hydraulic oil. (recommended machine oil 45-50℃. extreme value 30-60℃,stop production if the temperature is higher than 60℃ )

Hope above injection machine operation points is useful for you.
