Single-screw��Double-die-head Film Blowing Sets
-
This unit is used to blow high density polyethylene (HDPE), low density polyethylene (LDPE), and linear low density polyethylene (LLDPE) plastic films. Widely used in the packaging of household and industrial products such as food, clothing, textiles, and daily necessities.。
The machine adopts single-screw extrusion, double-die extrusion, and double traction and double-winding device with high output and low consumption. The screw and barrel are made of 38CRMOALA alloy steel, which is nitrided and precision machined, and has high hardness. The die is plated with hard chrome, the structure is spiral mandrel type, the extruded molten material is uniform, and the finish is good; the charging device adopts pressure and friction to control the winding, or the center is wound, and the torque motor is used for adjustment, the winding is smooth, and the roll changing is convenient. .
