SJRM65- 800 PVC plastic label film blowing machine

This machine use PVC plastic resin to make various hot shrink film under expanded-tube method processing. The film is high transparency, good lustre, high shrinkage, it is new popular packaging material nowadays. Widely used food, beverage, tea, glass products, handicraft, sanitary ware and cosmetics. Outerwear of products, electronic products, etc.


Features:

1. The unit is mainly composed of plastic extruder, air ring, head device, traction device, cooling device, heating expansion device, rewinding device, heating system and electronic control device.

2. The main parts of screw and barrel are made of 38GrMoAIA high-quality alloy steel, which has high hardness, wear resistance and corrosion resistance after finishing and ammoniation treatment.

3. advantaged screw with a length of 1:28 is suitable for mixing and plasticizing polyvinyl chloride (PVC) plastics with high melt viscosity and poor thermal stability.

4. The automatic temperature control system is equipped to control the heaters and cooling fans of the fuselage so as to keep the temperature constant, accurate and in line with the technological requirements of film production and ensure the excellent quality of the heat recovery film.

5. The special structure of die head and air ring is favorable for plasticizing and cooling requirements.

6. Easy to operate, compact structure, centralized control and high degree of automation.

The whole machine is divided into four parts: main machine part, traction device, temperature control box and Rewinding part. The details are as follows:
