Energy-Saving Automatic Cross-Linked PE Heat Shrink Sleeve Manufacturing Line with 0.5-3mm Sleeve Thickness

The Heat Shrink Sleeve production line is a modern production system integrating high efficiency and energy conservation with intelligent control. It consists of an LDPE base material extrusion production line, a heat-shrink tape gluing production line, forming processing equipment, and auxiliary equipment.

The entire set of units takes low energy consumption and low noise as its core advantages, supports precise speed regulation production, is equipped with an intelligent operating system, and meets the production requirements of high-standard anti-corrosion materials. This type of product has three different models:

1. The PE back film extrusion line produces PE film to meet clients' requirements,
2. sent the PE back film to a professional irradiation company to do radiation crosslinking treatment with the right radiation dose, so that the sleeve has Good fire resistance and tensile strength;
3. Put the irradiated back film into the heat-shrinkable sleeve adhesive coating production line for adhesive coating. In this process, the heat-shrinkable sleeve substrate is first stretched twice to ensure that the heat-shrinkable sleeve has a good shrinkage rate, and then a unique formula of hot melt adhesive is extruded by a professional reaction vessel and bonded with the back film. The finished product is peeled off. high strength.

Designed for pipeline joint protection, pipe rehabilitation, and wrapping applications, with typical uses including:

• Oil & gas transmission pipelines

• PU insulated pipes

• 3PE/2PE coated steel pipes
