Main Technical Specification:

8.The set has the advantages of compact structure, high degree of automation

7.The internal surface of die head is mirror polished and plated with hard chrome so as to reduce the film splits and increase the service life of die head.

6.Both the die head and the air ring are specially treated to make the plasticization and cooling effect better.

5.An automatic temperature control system provided with a digital display is used for controlling the heaters and machine body cooling fan in order to enable the temperature during plasticization to be stable and accurate and enable the plasticization to meet the requirements of film production process more so as to ensure the quality of heat shrinkable film.

4.Adopt a new type screw, which length-diameter ratio is 28:1. The screw is especially adapted for mixing and plasticizing the PVC, which has the disadvantages of high melt viscosity and bad thermal stability. The screw can strengthen the degree of plasticification.

3.Both the screw and the machine barrel are made of superior alloy steel- 38CrMoAL. After finish machining, the parts are hardened through nitrogen treatment, so they have the advantages of high hardness, wear resistance and corrosion resistance..

2.The set adopts the upper tractor for 360
