Molds of Film Blowing Machine

Main feature and purpose:

Along with the widely use of package film and the plastic film products are even more needed by people 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.This machine is compact structure, convenient operation, saving space and it is Intelligent facilities 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,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 materialgoes into the spiral machine head and flows into the die opening.At the last it gets into the film tube and extruded 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 and normally 3~7 times. If the drafting ratio is too large, the film will be easily broken.

Rewinding part

This machine has double friction rewinders and 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.
