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 produce plastic machinery series over 30 years' experience, collect similar machines' characters to produce this machine. The machine is special to blow film , such as HDPE, LDPE, dissoluble and reproducible plastic.

The forming frame can rise and down at random which makes the operation easy. And It also ensures good quality and this machine is compact structure, easy operation, less occupation of space. So it is the best equipment to produce plastic film.

Film Blowing Process:

Feeding → plastifying→ extruding →blowing out and extensing

→cooling and finalizing the design →traction→ rewinding

Feeding Process

When the equipment just start, should put litter material. Until the material is extruded and the machine head is normal .Besides the condition of plastifying is good, then add large quantities of material.

Plastifying process

The raw material goes out from the extruder and heated through 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 is from the screw pole extruding out section. It makes the original swirl material become the advection through the filter screen in machine head and then the material comes into the spiral machine head and flows into the die opening. Finally it becomes the cylinder filming tube and extruded out. 

The processes of film-blowing, lengthways towing  

After the film tube is drafted out, the size of film should be controlled well and the main processes are the blowing out section and the lengthways drafting section. 

Under the certain extruding machine rotating, the instant temperature and the changeless material discharging, also the dimension (width of breadth ) is decided by the ratio of blowing out and (the times of film’s transversed drafting ) can be 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 shape

The design finalizing is mainly decided by cooling vane（air ring） by air pressure and its function is to make the film tube extrude out from die opening. The plastic is cooled according the designed shape. It is adjusted in fine which makes the more precision section shape and brightness surface . After shaping, the material passes the drafting roll and comes into printing part.

Rewinding part

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