Molds of Film Blowing Machine

Main feature and purpose:

Under the development of package film , the plastic film products are needed by more pepole from day to day.Our factory has more than 30 years' experience to produce plastic machinery series introducing the similar machines' characters to produce this machine. This machine is special used to blow film with HD, LD, dissoluble and reproducible film.

The body frame can be adjusted to raise and fall within a certain range,the advantages make convenient operation and extra fine quality. This machine has the features of compact structure, convenient operation, saving space. It is Intelligent machines 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

Once the equipment start, we should put litter material in. Until the material is extruded , please make sure the machine head is right and the effect of plastifying is good. At last increase the quantities of material.

Plastifying process

The raw material goes out from the extruder and heated by preheat section, plastifying section and extruding out measurement section. It is mixed by screw pole and the grain material is plastified into fused mass. 

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 materialgoes into the spiral machine head and flows into the die opening. At last it gets into the film tube and extruded out. 

The processes of film-blowing, lengthways towing  

Two main processes ,extruding out and the lengthways drafting ,which makes the size of the film well after the filming tube is stretched. 

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 and normally 3~7 times. If the drafting ratio is too large, the film can easily broke out.

Cooling and finalizing the design

Cooling vane（air ring） and air pressure  decide The final main design . Its function is to make the film tube extrude out from die opening and the plastics cooled according to the designed shape and it is adjusted in fine. Section shape and brightness surface are more precise. After the shaped, the material passes the drafting roll and comes into printing part.

Rewinding part

This machine adopt double friction rewinders and cutting device. It could produce the single layer film and double layers rounded film according to clients’ requirements. It could double rewind in single layer or single rewind in two layers. The film should be rewinded smoothly.
