What is Film blowing?
Film blowing is a plastic processing method that refers to a plastic processing technology that heats and melts plastic particles and then blows them into a film. It usually uses polymer extrusion to form a tubular film blank, and then blows the tube film to the required thickness through high-pressure air under a good melt flow state, and then becomes a film after cooling and finalization. The quality of the film material blown by this processing technology is related to the film blowing machine and plastic particles.

The air ring is made of all-aluminum alloy with exquisite appearance;
Servo motor drive, ceramic heater, fan cooling;
Aluminum alloy silent lifting mechanism, highly flexible transition roller;
The herringbone frame is composed of two groups of wooden sheets and equipped with a ball positioning device, which can accurately control the angle of the herringbone frame;
The film blowing die head adopts the central feeding form, and the air inlet pipe is configured in the middle;
All operating parameters can be set, modified or displayed through a 7-inch true color touch screen, and it has a variety of interlocking protection and alarm functions.

Working Principle Of film blowing machine
Blow molding machine is a kind of plastic production machinery, the main working principle is: put dry polyethylene material into the hopper, by the weight of the material and it falls from the hopper into the screw, when the pellets contact the bevel of the screw, the rotating plastic generates thrust. The bevel ridge perpendicular to the plane, the plastic pellets move forward, this process continues, because of the friction of the plastic screw and the collision friction of the pellets, the time interval between the plastic and the barrel, and the gradual dissolution due to external heating. The molten plastic passes through the screw and the filter converter to filter impurities, extrusion die, cooling air ring and blown film through the herringbone plate, traction roller, winder, and finally the film is completed.
Types Of film blowing machine

desktop film blowing machine
The high performance desktop blown film machine. It is suitable for blown film forming of commonly used polymer materials such as PE. It can be used in combination with special accessories to achieve raw material dispersion detection, gel point, fish eye, and Expanded functions such as crystal dots, black dots and other film quality inspections are ideal experimental equipment for high-precision and high-performance film forming.
Three-layer co-extrusion film blowing machine
Small three layer blown film machine involves one process used to make plastic film. Extruded tubular processing is most often used with polyethylene films but can be used with other polymers.The film maybe laminating film, shrink film, agricultural covering film, bags or film for textiles and clothing, and other packaging materials.


Lab multi layer blown film line
The user can select the number of small lab extruder according to the structure of the multi layer blown film, and cooperate with the 2 layer blown film die, three layer blown film die or five layer blown film die to form a small lab multi-layer film blowing machine.
The film structure design can be divided into A/B, A/B/C, A/B/C/B/A, A/B/C/B/A, A/B/C/D/E symmetrical or asymmetric structure according to the die and numbers of small extruder.
Cast film blowing machine
The membrane rack is electrically lifted to facilitate membrane introduction and process adjustment. The vector wind ring is adopted, which is energy-saving and low in noise.
Each roller is independently driven, with a 0.4kW servo motor and a dedicated servo driver. The surface of the roller is plated with hard chromium, with a super mirror surface, hardness of HRC62-65, surface roughness of
Ra0.01 um, free of material contamination and delamination.
