Is the frequency of your glue melter issues becoming the center of production meeting conversations?
Do you have a solid Preventive Maintenance (PM) Schedule in place?
After you have a clean glue melter, implement a regular PM Schedule. It is recommended that the glue melter be purged every 3 to 6 months, based on your usage and type of glue. All filters should be changed at this time also.
Our DIY video can provide more details.
To reduce char build up:
- Set temperatures of the hoses, applicator heads and glue tank by recommendations made by the adhesive company on the adhesive specs. Some adhesives will char at temperatures that others will not.
- If the melter has a stand by feature, program unit to shut down when not in use. Heating the same adhesive for long periods of time breaks down the adhesive and may compromise its ability to adhere.
- Keep the glue tank as full as possible. When tank is not full, char will build up where there is a thin film of glue on the sides of the tank.
- Keep dry adhesive in a covered container to prevent contaminants from entering the adhesive. Auto feeders are a great alternative to keep glue tank full and provide a safer environment for employees.

Glue machines are a simple component of your packaging line and issues due to char do not need to be your focus.
