LD HD LLD Film Blowing Machine
If you are looking for new design,Website:, full automatic ld hd lld 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 ld hd lld film blowing machine for sale and providing with ld hd lld film blowing and printing machine, ld hd lld plastic film blown plant, ld hd lld plastic extrude film blowing machine on promotion, Yuzhe Intl Trading Company is always at your service.
Main feature and purpose:
The plastic film products are required with more and more customers with the Pervasive application of the package film.
Our factory produce plastic machinery series over 30 years' experience, collect similar machines' characters to produce this machine. The machine is special to blow film with HDPE,LDPE, dissoluble and reproducible plastic.
The base frame can go up and down within limits. The characteristic which ensures the easy operation and good quality and 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
Just the equipment start, put litter material , Until the material is extruded,ensure the machine head is normal and the condition of plastifying is good, then add large quantities of material.
Plastifying process
After the raw material goes out from the extruder and is heated through preheat section,it plasticizes and is extruded out, and then mixed by srew pole. Finally,the granular material is plastified into melt.
The Extruding out process
The fused material output from the screw pole extruding out section makes the original swirl material becoming the advection through the filter screen in machine head. Then, the material comes into the spiral machine head and flows into the die opening. Finally it becomes the cylinder filming tube, extruded out.
The processes of film-blowing, lengthways towing
After the filming tube is drafted out, the size of film should be controlled well. The main processes are the blowing out, the lengthways drafting parts.
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 lengthways drafting time decide the thickness of film , i.e. usually, the ratio is 3~7 times between drafting speed and the extruding speed. The film is easily broken out on the condition of the too large drafting ration.
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 is according to the designed shape and it is adjusted in fine which makes the more precision section shape and brightness surface. After the shaped, the material passes the drafting roll and comes into printing part.
Rewinding part
This machine adopt double friction rewinders with cutting device. It could produce the single layer film and double layers rounded film according to customers’ requirements. It could be double rewind in single layer or single rewind in two layers and the film should be rewinded smoothly.
