Single screw double-mode blower
For blowing a variety of low-density polyethylene (LDPE), high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) and other plastic film, widely used in food, clothing textiles, daily necessities and industrial packaging.
1, the machine using a single screw extrusion, double-mode membrane, with double traction, double-roll collection device with high yield and low consumption characteristics.
2, screws, barrels are using 38CRMOALA alloy steel, by nitride treatment and precision processing, high hardness, corrosion resistance, durable.
3, die plated hard chromium, its structure for the spiral spindle type, extruded melt uniform, blowing film finish is good;
4, the roll-up device using pressure friction collection, or center collection, the use of torque motor adjustment, roll flat, easy to change the volume.
