People who have just contacted the equipment of hot melt glue machine may have many doubts. How many kinds of hot melt glue machines are there? What is more suitable for their own process? Which one should be better?

In fact, there are only three types of hot melt glue machines: piston pump hot melt glue machine, gear pump hot melt glue machine and pur hot melt glue machine.

Different industries have different names for hot-melt glue dispensers, such as packaging hot-melt glue sprayer, mattress hot-melt glue dispenser, automobile hot-melt glue dispenser, cosmetics hot-melt glue dispenser, home appliances manual hot-melt glue sprayer, etc.

Although the name is different, but the principle is almost the same. It is composed of main machine, rubber tube and glue gun. The main machine is selected according to the needs of the industry. The main machine includes piston pump hot melt glue machine, gear pump hot melt glue machine and pur hot melt glue machine. The rubber tube is also selected according to the needs. The glue gun is divided into manual and automatic. All these are selected according to the needs of the process Choose the right machine.

Remember these principles, in the choice of hot melt adhesive machine will be very helpful. Hot melt adhesive machine belongs to high temperature products, high quality and suitable for their own process products can ensure that the production efficiency is doubled.

Multifunctional hot melt glue machine

The angle of the product is warped. The main reason for this situation is that too many sheets have been pasted so that the adhesive on the edge of the cardboard is dry and cannot be adhered. Generally, it is better to press 20 pieces.

The humidity of the product is too high (especially for the gold card). It is mainly due to the poor water penetration and dissipation ability of the gold card paper. The water content of the common flat adhesive is higher than that of the PE hot melt adhesive. We usually use quick drying glue or put the product in the sun.

The tile mounted or flat mounted products will turn yellow for a long time in the environment with high air humidity. It is mainly because some manufacturers use water glass glue or starch glue containing too much alkali. So in order to ensure the quality of our products, we should choose a good quality of flat paste and corrugated adhesive.

Some packaging products have delamination phenomenon, which is mainly caused by the insufficient strength of the adhesive. It is recommended to select some products from regular manufacturers, multi-functional hot melt glue machine, so as to ensure the strength, reduce the humidity, increase the stiffness, and improve the quality and grade of the packaging products.

Low temperature activity, if the low temperature performance is not good, we must use the method of water bath heating to make the glue temperature above 10 ℃. So as to achieve the purpose of full bonding.
