Characteristics of PVC Heat Shrink Film Blowing Machine:
1. The unit mainly by the plastic extrusion machine, the wind ring, nose devices, traction devices, cooling devices, heating and expansion device, rolling device, heating system and electric control devices and so on.
2. The key parts screw and barrel are 38GrMoAIA high-quality alloy steel, by ammonification after finishing treatment, with high hardness, wear resistance, corrosion resistance and other properties;
3. Using a new type of screw, 1: 23 length, suitable for high melt viscosity, poor thermal stability of PVC (PVC) plastic for mixing and plasticization, the degree of superior plasticization;
4. Configuration, automatic temperature control system controls the heater and cooling fan airframe so that the temperature constant throughout the process of plastination, accurate and consistent with the film production process requirements to ensure that the hot film to achieve outstanding collection of quality;
5. Mold head, the wind ring to adopt a special structure, in favor of plastics and cooling requirements;
6. Easy to operate, compact structure, control of concentration, a higher degree of automation.
