Three Layer Film Blowing Machi

If you are looking for new design,Website:http://www.yuzhe-honghua.com, full automatic three layer film blowing machine, or you are going to import high speed PLC control products from a such factory, or you are planning to check the price with a such golden supplier, with large output three layer film blowing machine for sale and providing with three layer film blowing and printing machine, three layer plastic film blown plant, three layer plastic extrude film blowing machine on promotion, Yuzhe Intl Trading Company is always at your service. Main feature and purpose: With the extensive use of package film, the products of the plastic film are more demanded by people day by day.Our factory has more than 30 years' experience to produce plastic machinery series, introduce the similar machines' characters to produce this machine .The machine is special used to blow film, such as HD, LD, dissoluble and reproducible film. The base frame can go up and down within limits, the characteristic ensures the easy operation and good quality. This machine is compact-sized, simple operation, less space, it is the perfect device to produce plastic film. Step of the Film Blowing: Feeding→plastifying→extruding→blowing out and extensing →cooling and finalizing the design→traction→ traction →rewinding Feeding Process and Plastifying process Once the equipment start, should put litter materual. Until the material is extruded ,make sure the machine head is right and the effect of plastifying is good, then increase the quantities of material.After the raw material goes out from the extruder and is heated through preheat section, it plasticizes and is extruded out, then mixed by srew pole, and finally, the granular material is plastified into melt.  The Extruding out process The fused material output from the screw pole extrudeding out section, which makes the swirl material turn into the advection by the filter screen in the equipment head. Then ,the material goes into the spiral machine head and flows into the die opening.At the last it gets into the film tube and extruded out.  The processes of film-blowing, lengthways towing   The main processes are the extruding out and the lengthways drafting to control the size of film well just the filming tube is drafted out.  Under the certain extruding machine rotating, the instant temperature and the changeless material discharging, the size (width of breadth ) is decided by the ratio of blowing out, which (the times of film’s transversed drafting ) is easily operated under 3 ~ 6 times.  The thickness of film is decided by the lengthways drafting time, i.e. the ratio between drafting speed and the extruding speed, normally 3~7 times. If the drafting ration is too large, the film is easily broken . Cooling and finalizing the design The design finalizing is mainly decided by cooling vane（air ring）and air pressure and its function is to make the film tube extrude out from die opening .The plastics cooled according the designed shape and it is adjusted in fine. The more precision section shape and brightness surface and after the shaped, the material passes the drafting roll and comes into printing part. Rewinding part This machine applies double friction rewinders with cutting device. It could produce the single layer film and double layers rounded film according to clients’ requirements. It could be double rewind in single layer or single rewind in two layers and the film should be rewinded smoothly.   Molds of Film Blowing Machine Mold HL-45-600 HL-50-800 HL-65-1000 HL-80-1500 HL-120-3000 Material HDPE, LDPE, LLDPE, Recycling material, Biodegradable material.
