The ABA blow molding machine is a double extruder. The membrane head is designed to be three layers. Inside and outside is a screw extruder that is AA. In the middle is B layer, another screw is used for extrusion. ABA is mainly used to increase membrane tension and reduce cost. It can increase the filling of 20/ more than single screw machine. Used for blowing high and low pressure polyethylene, products are widely used in composite film, packaging film, agricultural covering film, textiles, clothing bags or film packaging.
The main motor adopts frequency conversion speed regulation, which increases the stability of the main motor speed regulation and saves 30% electricity. The screw barrel adopts 38 chromium, molybdenum and aluminium. After nitriding treatment, the traction frame adopts lifting type, and the cooling effect can be better regardless of blown large or small size film.
It is suitable for blowing low density polyethylene (LDPE), high density polyethylene (HDPE), and linear low density polyethylene (LLDPE) plastic film, and can be filled with calcium carbonate 20% - 50%. The main advantage is that the pulling force is good. The two-layer film blower blows a lot better than the single-layer 6-wire thick product. Then the output is high, and the two sides of the double-layer co-extrusion film blower can make different colors.
