Film blowing machine production process

Blown film machine process principle Dry polyethylene particles will be added to the next hopper, relying on the weight of the particle itself from the hopper into the screw, when the aggregates and thread oblique edge contact, the rotation oblique edge of the plastic surface with oblique plane perpendicular Thrust, the plastic particles move forward, the process of moving, due to plastic and screw, plastic and barrel friction between the friction and friction between the particles, but also because the external heating tube and gradually melt. Molten plastic filter through the head to the impurity from the mold die out of the mouth by the wind ring cooling, inflation by the word plate, traction roller, the roll will be finished film roll into the tube
