Used for blowing the plastic film of low density polyethylene(LDPE), high density polythylene(HDPE)
The unit extruder, barrel, screw adopt high-quality steel, nitride tight handling and precision machining, with the best hardness and corrosion resistance, a specially designed screw high yield, good plastics. Applicable to the blowing high and low -density polyethylene (HDPE, LDPE), linear low density polyethylene (LLDPE), such as plastic film, widely used in food, clothing, garbage bags, vests bags, and other civil and industrial packaging
1. The main motor adopts frequency control of motor speed to improve the speed regulating stability of main motor and save electricity.
2. The screw and material barrel adopt 38 CRMOALA which has been nitrogen treated
Material of screw and barrel: 38CrMoAlA Polished with Nitride Treatment
Hardness of heat treatment: Screw HV≥ 740, barrel HV≥ 900
Depth of hardening: 0.6-0.7mm: 0.6-0.7mm
Brittleness grade: Bigger than 2 grade lower than2 grade
3. The traction frame adopts lifting type. No matter what size the film is, big or small, it can achieve the best effect of cooling.
4. The die adopts advanced central head feeding spiral runner molding technology.
5. Molding and cooling of the film adopts air blower and air ring with high-property, low air pressure, and large air volume.
6 The extruder adopts corrugated screw with oblique barrier and mixing head, which assures stable and reliable performance, high output and low energy consumption.
7. It adopts friction type double surface wind-up, which has improved the flatness of the film, and made the coiling structure tight. It is easier to operate. A length metering device is installed, which makes the length of the film accuracy.
8. Edge cutting device: With 2 pcs edge slitting blade or 2 pcs center slitting blade. Just For double winder
9. The electrical components are domestic famous brand or world famouse brand
10. The Invrter, Delta brand ( in the world, it has many salers sevices. Like Egypt -Cairo, Iran-Tehran, UAE-Dubai, Patistan-Karachi, Chile -Santiago, peru-Lima...Many many
