Polyurethane foaming machineThere are many reasons why the black material is not heated in the working process.

(1) booster pump air source pressure

1. Triplet pressure relief valve adjust air source pressure is too low

2. The air compressor exhaust pressure can not meet the use requirements of foaming equipment

3. The trachea from the air compressor to the foaming equipment is too thin and too long

4. Excessive moisture in compressed air impedes air flow

(2) raw material temperature

1.Polyurethane foaming machineThe heating temperature of raw materials is not enough

2.The initial temperature of raw material is too low and beyond the range of equipment
