<h1>
Lab film blowing machine / PLC control
</h1>

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.

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.

Features


■  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.
