Dalian plastics blown film machineWill dry polyethylene particles added to the hopper, depend on the weight of the particles themselves from the hopper into the screw, as well as the external heating cylinder and gradually melt, the molten plastic by the nose mouth came out from the die and approved by the wind ring cooling, blowing the steady bubble herringbone plates of traction roller coiling the finished film rolled into a cylinder.
Blown film process, material plasticizing extruder, forming a bad blow molding;Cooling, traction, coiling.In blown film forming process, depending on the direction of extrusion and drawing, and can be divided into flat under the blow, blow, blow three, this is the main molding process also have special blow molding, squeezing method as above.
