Hot melt glue machine with hand gun

The reason why the sealing machine is not strong

August 14 , 2021

1. Material selection of the box:

The selection error mainly refers to the imperfect matching of the hot melt adhesive or the type of boxes that need to be bonded, and it is difficult to meet the process requirements of the material itself.

2. The temperature during compounding does not meet the requirements:

The compounding temperature does not reach the melting point of the adhesive film or omentum, resulting in insufficient melting of the hot melt adhesive and insufficient bonding performance.

3. Compatibility of materials:

There are also differences in the application range of hot melt adhesives/films of different materials. The surface of the bonded object has not been cleaned up, and there is dust or impurities that affect the bonding.
