How to solve glue gun leakage
Jun 20 , 2024
1. Glue leakage at the Hot melt gluing nozzle If glue leaks from the nozzle during glue spraying, the possible reasons are as follows: a. The temperature of the glue gun is not enough. The temperature of the hot melt glue gun should be increased appropriately. b. If the pressure or flow rate of the air jet is too small, glue will drip from the nozzle. Increase the pressure of the air blowing...
