Its extruder, cylinder and screw rods are made of quality alloy steel that have been nitrizied and processed in a precision way. Hence it is sound in hardness, durable in corrosion resistance. The specially-designed screw is of sound quality in plasticizing, which helps increase the production capacity. It is applied to blowing the plastic films like low density polythene(LDPE),high density polythene(HDPE)and linear low density polythene(LLDPE).It is widely applied to producing the packing bags for foodstuff, clothing, rubbish bag and vest ones.
Features
1. Whole machine is made of one set of traction main engine, double barrels and one die. Two barrels feed material, one die extrude the film and traction rolling device which can improve the color bar film outputs.
2. Screw and barrel are made of 38CrMoAl that have been nitrizied and processed in a precision way. Good hardness, hight corrosion resistance and wear well.
3. Die with hard chrome plating, spiral core shaft type. The meltingcharge extruded in equality, and the film blown with good fineness. Air cooling device is U maze with balance airflow.
Rolling device with surface friction type or centre rolling type which adjusted by torque motor to make rolling even and roll- changing easy.
OPTIONAL EQUIPMENT
1)AUTO LOADER 2) CAST ALUM HEATER 3)AIR SHAFT 4)PNEUMATIC DEVICE
