ALUMINUM PROFILE EXTRUSION MACHINE TROUBLESHOOTING METHOD:

1. Check the power connection of the main motor. Check the temperature of each part, confirm the warm-up time, check the heater for damage or poor wiring.

2. Adjust the pulley center distance and belt tension. Repair the gearbox.

3. Feed the hopper. Remove foreign objects from the discharge hopper or eliminate the bridge, lower the temperature of the feed port, check if the cooling water passes, and check if the temperature of the material is too high or too long. Stop the machine immediately, remove the screws, remove the hard object, close immediately, remove the screws, repair or replace. Check the screw cooling water system, increase the screw cooling water volume, lower the temperature, and check the material properties. Stop immediately. Remove the screw check. Check materials and properties (some materials are easy to slip, such as PP). Adding additives to the additive can cause slippage. We must constantly test the temperature to find the most suitable extrusion temperature.

4. Replace the material, the screw can be directly cleaned, and the heavy-duty screw can be manually disassembled and cleaned.

5. Check that the wiring of each heater is correct or firm, check the motor bearings, add lubricant or replace the bearings.

6. Check the main motor and control system. Adjust the heating power, check whether the thermocouple is in contact with and installed, whether the thermocouple is damaged, and replace the thermocouple if necessary.
