The hot melt adhesive cools before bonding, and the cold sticking phenomenon is stable. The reasons for the cold sticking phenomenon and the solutions are as follows:

1. The use temperature of hot melt adhesive is low, and the use temperature is increased

2. The opening distance is too long, reduce the opening distance

3. The conveyor speed is too slow, increase the conveyor speed

4. The amount of glue is not enough, increase the amount of glue

5. The temperature of the bonded material and the environment is low, and the temperature of the environment or the bonded material is increased

6. Adjust the pressure if it is inappropriate

The cold sticking phenomenon of hot melt adhesive needs to be analyzed for different reasons and corresponding solutions are obtained
