How to make the best use of polyurethane foaming machine? Take a look at the common sense of polyurethane foaming machine.

1. Start the industrial chiller, set the required temperature, and control the material temperature to the appropriate position.

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

3. Start the high pressure cycle to make the circulation of black and white materials in the material tank and the circulating water heat exchange in the industrial chiller, so that the material temperature of black and white materials can reach the set temperature requirements.

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

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

6. Start the main brake for polyurethane foaming machine and the POWER knob on the left side of the instrument panel, and the POWER SUPPLY indicator will turn green. Then start the oil pressure system.

7. After the production of the polyurethane foaming machine closes the nitrogen cylinder air valve and compressed air inlet valve, then stop the internal circulation of the foaming machine, reset the left power button and pull down the main brake to turn off the power.
