Characteristic and use :
Uses in blowing system each kind of low density polyethylene (LDPE), high density polyethylene (HDPE) and plastic membranes and so on linear low density polyethylene (LLDPE). Widely applies in food, the clothing textile, the daily necessities and the industrial product packing.

1st, this machine uses the single screw rod to squeeze out, the double find the clue make it out membrane, matches by the double hauling, the double volume takes the installment to have the high production low consumption characteristic.

2ed,The screw rod, the feeding trough use the 38CRMOALA alloy steel, becomes after the nitriding and the precise processing, degree of hardness is high, corrosion-resisting, durable.

3th,The die head plates the hard chromium, its structure for the spiral core shaft type, the fusing material which squeezes out is even, blows the system the thin film smooth finish to be good; Forced-air cooling installment structure for labyrinth, air output even.

4th,The volume takes the installment to use the pressure friction to receive the volume, or the center receives the volume, uses the moment of force electrical machinery adjustment, receives the volume smoothly, trades the volume to be convenient.
