For the whole process of film blowing, the Blown Film Extruder is one of the most significant devices among the machine to produce plastic film. By the mixing of screw and barrel, and the continuous heating to maintain the suitable temperature, the material will become molten type. Squeezing and pressurizing the material, it will be transported to Extrusion Filter where the impurities are removed out. Then flow into the Extrusion Die Head for film blowing.
Plastic Film Blowing Machine is used to make the raw materials into the plastic film. Putting the raw material into the hopper, the material presents a granular type at first. When the extrusion starts working, the drive system prompts the screw to start whirling. In order to let raw material melt and mix completely, the heater which installed along the barrel with the electric control is available to adjust its temperature. Also, the air ring device will drop the temperature down and keep the air bubble with a stable situation in case of an overheat situation happen. By the pressure extruding, all the components will be pushed forward to the filter. Cleaning the impurities out, the molten polymer is then forced into the Extrusion Die Head where the film comes out and shapes like an air bubble. The temperature keeps heat at this part until film arrives at the air ring to cool down.
In order to guarantee the quality of Die products, we use different precision devices to check inspect each part.
According to the various applications of Plastic Film Blowing Machine, HSIN LONG had designed and manufactured a serious of components of our Blown Film Extruders and got better quality control to the key components. As one of the central components, Blown Film Extruder is divided into Single Layer Extruder, ABA / Double Die Extruders and Co-Extruders for customers to choose.
