Hot melt glue machine
and cold glue machine are both special equipment for spraying glue, but their application fields are very different. So what is the difference between them?

Hot melt glue machine uses gel glue, which is commonly known as jelly glue. Because the shape and performance of gel glue are a bit like jelly, it is also called jelly glue. Its characteristics are: odorless, strong viscosity, good fluidity, strong foldability, and fast drying time. Therefore, after using the hot melt glue machine, it can avoid the shrinkage and mold of white latex, and the glue dries slowly. It can also solve the deformation, brittleness, and bubbling of some products after long-term storage. It will not corrode the machine, is environmentally friendly and durable, and is deeply favored by customers in various industries!

Cold glue machine uses common water-based glue such as white latex. Performance: White latex is not afraid of insects and rats, will not mold or deteriorate, is harmless to the human body, is easy to wash, can be diluted at will, and is easy to use; the disadvantage is that this adhesive has poor water resistance and heat resistance. Usage: It is particularly suitable for bonding porous materials, such as paper, fabrics, leather, and wood. It dries very slowly and is not easy to set.

With the improvement of living standards, people have more and more requirements. For example, cold glue machines cannot be used in the food industry, while hot melt adhesive is an environmentally friendly material and is widely used in: disposable sanitary materials, maternal and child hygiene products, non-woven fabrics, book binding, footwear, medical supplies, furniture manufacturing, automobile manufacturing, air filter production, adhesive tape, trademark labels, packaging industry (carton sealing, color box sealing) and express bags and other major industries.

The main reason is that the cold glue spray machine has a small application range, is not environmentally friendly, has certain harm to the human body, and has low viscosity, while hot melt glue coating equipment has become one of the indispensable mechanical equipment for many manufacturers. From the perspective of future development prospects, cold glue spray machines will inevitably fade in people’s sight, and hot melt glue spray machines will replace them!
