Application & Process

The laboratory blown film extruder processes plastic melt through continuous extrusion under controlled temperature and shearing force. The material is inflated by compressed air, cooled by air ring systems, and drawn by frequency conversion traction to produce bi-fold plastic film. This machine is primarily used for evaluating polymer material blown film feasibility, detecting gel conditions in materials, and assessing color dispersion, control mixtures, and extrudate quality.
