From packaging to manufacturing, continuous hot melt equipment maintenance can transform your equipment's performance. In this blog post, we'll explore essential tips to help you maintain a clean and efficient hot melt system.

Tips for Hot Melt Equipment Maintenance

Conduct Regular Inspections and Cleanings

Regular inspections are a vital first step in preventing issues before they arise. Develop a routine maintenance schedule that includes thorough cleaning and assessment. Check for any residue buildup, dirt, or contaminants on the equipment components, such as nozzles, hoses, and applicators. Your compliance program or ISO team can develop standards and guidelines for implementing this important checkpoint on a regular basis.  

Use Quality Adhesives

The caliber of the adhesive you use, can significantly impact the cleanliness of your hot melt equipment. Opt for high-quality products with minimal char and carbonizing tendencies. Second-rate adhesives can cause charring and nozzle plugs, which will increase downtime and impact the overall efficiency of your system. Getting a top-shelf product is worth the battle with procurement if it will reduce spare parts and provide large cost savings in the long run.

Purge System Regularly

Purging your systems can prevent cross-contamination of adhesives and ensure ultimate performance. Run our P8200 hot melt purge or low-viscosity adhesive through your equipment to flush out residue and eliminate buildup.

Astro Packaging offers a hot melt tank cleaning and service kit to help maximize the performance and lifetime of your equipment. It includes a purge solution, gloves, brushes, safety glasses, and a sealable bucket for disposal. All this, and more, will remove dirt and charred material in nozzles and melters, eliminating downtime and poor production.

Temperature Control

Efficient hot melt application relies on proper temperature settings. Excessive temperatures can lead to adhesive carbonization and residue buildup, while insufficient heat may result in poor bonding and impact the end product. Regularly calibrate and monitor the temperature to ensure your system runs efficiently and operates within the recommended range.

Invest in Hot Melt Filtration Systems

Effective filtration systems can significantly reduce the likelihood of contaminants reaching the hot melt system. Hot melt filters capture impurities in the adhesives, preventing them from clogging nozzles and other components.

You can purchase inline filters from Astro Packaging to prevent char and debris from passing through your hot melt glue system. A QC officer would back up this investment.

Store Adhesives Properly

High-quality adhesives will improve the performance of your hot melt system. Store adhesives in a cool, dry place, away from direct sunlight. Proper storage prevents the adhesives from degrading and forming impurities that could compromise your machinery and packages.

Train Operators

Train operators on the correct procedures for loading adhesives, adjusting temperatures, and performing routine maintenance tasks. Educated operators are more likely to identify and address issues before they escalate, contributing to the longevity of the equipment.
