Different methods are adopted for the gelatinization of heat-shrinkable materials according to the needs of customers and different products, mainly including three methods for the gelatinization of base material and the gelatinization of hot-melt co-extruding gelatinization machine, such as spiral gelatinization and straight gelatinization

The co-extrusion method is mainly used in double-wall heat shrinkable tube. The glue layer coated in this way is thinner and more uniform, and the glue layer is also applied successfully when the heat shrinkable tube is formed. There is no need to apply glue separately.

Glue coating machine: place the hot melt adhesive in funnel coating machine heating, use machine will melt after the hot melt adhesive evenly coated on the inner wall of the heat shrinkable tube, this method is applicable to large broken shape heat shrinkable tube of glue, such as the thick wall heat shrinkable tube of glue way is using the method of artificial participation is more, the product quality are greatly influenced by the outside world, but what this method apply gum rubber thicker, waterproof seal is superior anti-corrosion performance.

Manual glue: in fact is human use tool dipped in hot melt adhesive, and then quickly to the heat shrinkable tube wall coating, this coating technology performance is poor, the coating quality affected by human factors, products inside coating is very uneven, so the quality can't get effective control, sealed performance is poor, where high-voltage waterproof demand highly fit, will cause the safety accident hand coated adhesive solution heat shrinkable products inside intermittent, shades, greatly affect the quality of the product is a kind of low quality and high cost of the production process of this technology is mainly used in hot shrinkage refers to the set of type of glue.

Spiral spraying: this is a more advanced coating technology, using automated machinery coating equipment under program control injection on the inner wall of the heat shrinkable products, the coating technology, spray evenly strip hot melt adhesive solution, heat shrinkable products after retraction, inside the walls of a spiral on the hot melt adhesive, its sealing performance compared with the same hand 3 times of glue quantity, the better sealing waterproofing coating process rivals, more is not easy to fall off is mainly used in the heat shrinkable cable seal cap and short thick wall pipe.
