Cast film extrusion line consist of a lab precise single screw extruder, a molding system(die), a film casting, haul-off & winding machine and a SIEMENS PLC Touching Screen Control System. It not only has wide range of technology adjustment (including speed, temperature, pressure, thickness, etc.), but also has a lot of functions such as real-time parameter acquistion, graphic displaying, recording and storing. It is an ideal tool for research institute to develop new material formula and film shaping technology.
Application
1) Polymer casting property test
2) New material formula development
3) Optimization of production technology
4) Production quality control.
