Product Description

Lab film blowing machine / PLC control

Extrusion film blowing refers to the technological process that the double-folded plastic film made by compressed air huffing, vane cooling and frequency conversion traction and the plastic melt being extruded through dies at a certain temperature and certain cutting force.

The film blowing machine consisted of single screw extruder and film blowing tower, it is mainly used for testing the film blowing feasibility of polymer materials and the colloid status contained in the materials.


1. Single screw extruder

Screw diameter Φ 20
Length diameter ratio 1:28
Screw speed 0 - 95 rpm frequency control
Screw/Feeding barrel material:

38CrMoAl chromium-molybdenum steel. With the surface-layer processing of tempering, nitriding, chroming, polishing and super-precision grinding, the hardness HRC55~60, roughness Ra≤0.4μm, nitriding depth≥0.6mm.

Electric control system:

PLC programmable color touch screen, man-machine interface operation system, can dynamically display and monitor extrusion process, including temperature control, driving, pressure, interlocking spreading function.

2. Film blowing tower

Diameter of dies Φ 30
Driving rolling speed 0- 5 m/min adjustable
Maximum folded diameter of the film 150 mm
Servo motor 90 W
Fan 0.25 KW
Rolling torque motor 3.5 N.m
Illuminating case LED light
Huffing air:

Compressed air 0 -6 bar, can be fine adjusted and stabilized.

Cooling air:

Blower flow 30 L/min, can be fine adjusted and stabilized.

Film Blowing Machine Details


This machine has compact design and a small body, not occupying too much indoor area.

The host and auxiliary machines are of easy assembly with few raw material. The maximum folded diameter of the thin film can reach200mm.

This machine is equipped with the C-type fast changing handpiece of easy operation and time & labor-saving test.

Single-layer or double-layer cooling vane and the closed-loop control of creasing width ensure reliable product quality.

The spiral circulation film blowing die of high performance is easy to clean and maintain.

The height of the filming blow tower can be adjusted arbitrarily to meet test requirements.

The extrusion, traction and rolling have the property of stepless speed regulating, ensuring requirements of film blowing technology to be met.
