There are several common troubleshooting problems that can occur with hot melt equipment, but two of the most common ones are:
- Adhesive charring or carbonization: This occurs when the adhesive overheats and burns, which can lead to clogging in the equipment and affect the quality of the adhesive application. Adhesive charring can be caused by a number of factors, such as incorrect temperature settings, dirty or clogged nozzles or filters, and adhesive build-up on the equipment. To troubleshoot this issue, it is important to check and adjust the temperature settings, clean the nozzles and filters, and regularly maintain the equipment to prevent adhesive build-up.
- Adhesive stringing or dripping: This occurs when the adhesive does not properly bond or cool down after application, which can lead to stringing or dripping of adhesive. Adhesive stringing or dripping can be caused by a number of factors, such as incorrect temperature settings, incorrect adhesive viscosity or formulation, incorrect pressure settings, and worn or damaged equipment components. To troubleshoot this issue, it is important to check and adjust the temperature, pressure, and adhesive viscosity settings, replace worn or damaged components, and regularly maintain the equipment to ensure optimal performance
