ABA Professional Garbage Bag Film Blowing Machine

A+B+A  three layers co-extrusion one die film blowing machine includes two screws, one of which provide the raw materials for the outer and inner layer while the other one provide for the middle layer. Whether producing HDPE or LDPE ,it has great capability and unique advantage.By three layer co-extrusion, it improves the intensty ,lowers the cost and successfully achieved the goals of energy saving.

All the die heads our factory produce is 40 CR materials, finally take shape after many times treatment and carefully processing . Helix is processed in the imported four-axis linkage machining center, which ensures the accuracy and the spiral ways well distributed the material.   After carefully grinding and polishing ,each runners of the head are plated hard chrome, which increase the die's abrasive resistance and corrosion resistance.
Die processing:
1. material of the die: 40 cr steel , after manytimes carefully processing
2. Forging :forging the ingredients into a coarse ring of the mold to make the molecular structure more compact
3. Lathe processing: lathe the die with high precision lathe according to the drawing by  the sophisticated master .
4. Polishing: polish the runners , the higher the finish , the better the film
5. chroming: enhance the abrasive resistance and corrosion resistance

The importance of selecting the die head :
1. material selection: if the steel is of bad quality , due to the heat-expansion and cold-contraction, the die head will greatly deform after a few times' use, the film thickness will be naturally uneven.
2. The helix inside the die head if improper processed, the spiral groove will be irregular. uneven distribution, poor plating and unconform compression ratio can cause uneven discharging , decreasing film brightness , defective plasticizing, difficult to eliminate the fusion line etc.
