Description

Technical Field

[0002] Heat shrink tubing is a special polyolefin heat shrink tubing. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance. The inner layer has the advantages of low melting point, waterproof sealing, and high adhesion. During production, the heat shrink tubing is heated to a highly elastic state, and a load is applied to make it expand. While maintaining the expansion, it is quickly cooled to make it enter a glass state. When heated during use, it will return to a highly elastic state, but at this time the load is gone and it will shrink.

[0003] Therefore, the processing of heat shrink tubes is to use hot melt extrusion equipment to heat and melt the polyolefin material, and extrude it into a tube through the die head. During the extrusion of the extruder, the extruded tube will have a high temperature, and the heat shrink tube will be deformed due to the high temperature when it is discharged. Therefore, we proposed a heat shrink tube extrusion equipment to improve the above problems. Utility Model Content
