♦Plastic wrapping extrusion line composition:
1、 Unwinding (feeding) device: according to the different cores to be wrapped, choose the corresponding matching device.
2、 Main machine: according to the size and material of the outer layer, different specifications of single-screw extruder or twin-screw extruder can be selected.
3、 Coating die
4、 Cooling and shaping water tank
5、 Traction machine
6、 Cutting or winding equipment
According to the situation, we can choose an EDM tester and diameter meter to accurately measure wrapping quality and adjust the corresponding diameter change parameters.
Film Blowing Die
♦Extrusion blown film is the process of extruding the plastic melt continuously through the mouth die to be extruded under the action of a certain temperature and a certain shear force, and the bifold plastic film is obtained by compressed air blowing, wind ring cooling, and frequency conversion traction.
♦It is mainly used to test the feasibility of blown film of polymer materials and the gelatinous condition within the material, as well as the dispersion of colored dispersions, control mixtures, and extrudates.
