Dalian blown film crewSeveral main components, such as the extruder, head, cold wind ring, traction and winding, etc., a set of good qualityBlown film machineRequirements from extrusion until the whole process of winding are not defects, if any one link in the design principle and manufacturing quality problems, quality of manufactured products will reduce a lot, that influence use and market, this problem should be caused take seriously.

Blown film machineGroup is mainly composed of extruder, head, head, cooling device, stable foam frame, herringbone board, traction roll, coiling device and so on, the air compressor output of compressed air, storage tank after tank outlet valve into the die head screw mandrel center hole.

Die entered equipped with a pressure adjusting cutting, according to the requirements of products size to adjust volume, pressure, gas through the mandrel center hole into the bubble tube, blowing extrusion plastic film into bubble tube shape.
