There are many kinds of glue spraying methods for hot melt glue machines. Some industries need glue spraying effects, and some industries need glue scraping effects. These are all selected according to the customer's process requirements.

The hot melt glue guns used for glue spraying and squeegeeing of hot melt glue machine equipment are different, see the picture below:

Where is the specific difference?

1. The glue gun used for glue spraying does not need to be in contact with the material, there is a certain distance, the glue gun can spray out dots, lines, spirals or different shapes. The glue scraping gun needs to be in contact with the material, and the glue scraped out is relatively wide.

2. Through these two methods, the shape of the hot melt adhesive on the material is different. The glue sprayed out is relatively narrow, has a certain thickness, and the surface of the glue is uneven, while the glue scraped out is relatively wide, the glue layer is very thin, and the surface is even.

There is a big difference between glue spraying and squeegeeing, so when choosing the configuration of the hot melt adhesive machine, it is necessary to communicate with the hot melt adhesive machine manufacturer in detail about the process and choose the appropriate method.
