The hot melt adhesive cools down before bonding, which is also called cold bonding. The reasons and solutions for the cold bonding phenomenon are as follows:

(1) The hot melt adhesive application temperature is low → increase the application temperature;

(2) The open distance is too long → reduce the open distance;

(3) The conveyor belt speed is too slow → increase the conveyor belt speed;

(4) The amount of glue applied is insufficient → increase the amount of glue applied;

(5) The temperature of the bonded material and the environment is low → increase the temperature of the environment or the bonded material;

(6) The pressure is not appropriate → adjust the pressure.

If the hot melt adhesive has the cold bonding phenomenon, it is necessary to analyze the different reasons one by one and obtain the corresponding solutions.
