Daily maintenance of polyurethane foaming machine

Polyurethane foaming machine can be used for automobile interior decoration, thermal insulation wall spraying, thermal insulation pipe manufacturing, and processing of bicycle and motorcycle seat sponges. So what do you need to use when using a polyurethane foam machine? Next, we will introduce its daily maintenance operation.

1. Close the feed valve, start the nitrogen cylinder pressure valve to inflate and pressurize, and open the compressed air valve to make it reach a specific pressure.

2. Add material to the barrel of the polyurethane foaming machine, do not add the wrong material, and see the AB material clearly;

3. Start the special main gate of the polyurethane foaming machine and the power knob on the left side of the instrument panel, the POWER SUPPLY indicator will turn green, and then start the oil pressure system. After it is stable, press the low pressure cycle button to start the low pressure cycle.

4. Start the industrial chiller, set the required temperature, and control the material temperature to a suitable position;.

5. Set the injection time on the instrument panel, and perform injection according to the corresponding requirements on the gun head.

6. Start the high-pressure cycle, so that the black and white material in the tank exchanges heat with the circulating water in the industrial chiller, so that the material temperature of the black and white material reaches the set temperature requirement.

7. After the production of the polyurethane foaming machine is completed, close the nitrogen cylinder gas valve and the compressed air intake valve, then stop the internal circulation of the foaming machine, reset the left power button and pull down the main gate to turn off the power.
