An extruder that melts and extrudes the raw material through a die and then expands it with air pressure. The extruder can adjust the diameter, thickness, and length of the tubing according to the specifications.
It can produce single wall heat shrink tubing from various materials, such as polyolefin, fluoropolymer, elastomer, etc. Each material has different properties, such as flexibility, temperature resistance, chemical resistance, flame retardance, etc
The main components of heat shrink tubing extrusion production line: Extruder — Extrusion Die — Cooling and Setting Water Tank — Tractor — Winder
The main components of the heat shrink tubing expansion production line: Unwinding stand—tube blank feeding–glycerin heating box–die positioning–vacuum control–water cooling–traction output
Single Wall Heat Shrink Tubing Extrusion&Expansion Production Line
1. Heat Shrink Tubing Extruder Models:
SJ-30 extruder, SJ-45 extruder, SJ-50 extruder,
SJ-55 extruder, SJ-65 extruder, SJ-75 extruder,
SJ-90 extruder, SJ-120 extruder.
2. Heat Shrink Tubing Extrusion Die:
Within a certain range, dies of different specifications can be replaced to produce products of different specifications.
3. Two types Cooling and Shaping Water Tanks:
Immersion cooling and shaping water tank and vacuum cooling and shaping water tank.
Immersion cooling and shaping water tank is mainly used for extrusion cooling and shaping of small-size heat shrink tubing,
Vacuum cooling and shaping tank is mainly used for extrusion cooling and shaping large-size heat-shrink tubing.
4. Two types Tractors :
Twin-roll tractor (composed of two pairs of rubber rollers) is mainly used for the extrusion and traction of small-size heat shrink tubing,
Crawler tractor (two traction tracks composed of a rubber belt or rubber block) is mainly used for the extrusion and traction of large-size heat shrink tubing
5. Winding Machine:
Large-diameter winding machines are used to prepare for the next step (preparation for electron accelerator irradiation) Small-size heat shrink tubing needs to be plied and winded to the winding plate together and then the branching machine separates the tubing after irradiation.

1. Unwinding stand: made of the square tube or section steel, the unwinding reel rotates freely on it
2. Tube Billet Traction and Feeding Part: driven by the motor, the rubber roller feeds the tube billet into the glycerin box
3. Glycerin Heating Tank: electric heating of glycerin to heat the tube blank, so that the irradiated tube blank reaches a molten high-elastic state
4. Glycerin Heating and Conveying Section: the transmission part is driven by the motor to realize the continuous and uniform transportation of the tube billet in the glycerin tank
5. Die Positioning Part: used to install expansion die
6. Vacuum Control Part: control the vacuum size of the die
7. Water Cooling Part: control the water volume of the die, and cool the expanded heat shrink tubing
8. Traction Output Part: the motor drives the rubber roller to pull and output the expanded heat shrink tubing
9. Finished product Transport Output
