How to reduce costs due to high consumption of hot melt adhesive particles? First, check these 4 places

Direct answer: The consumption of adhesive particles is relatively high, and 90% of the problem lies in four areas – excessive setting of adhesive amount, waste caused by improper temperature, equipment leakage, and mismatched selection of adhesive particles. After item by item investigation, most factories can reduce unit adhesive consumption by 15% -30% without sacrificing bonding quality.

Four investigation points

• Glue amount settingThe thicker the glue, the stronger it is. The back adhesive layer of 0.6-1 millimeters and the sealing adhesive strip of 2-3 millimeters are sufficient. Adjusting the adhesive amount from “extra dots for safety” to the standard value is the most immediate cost reduction method;
• Temperature managementOvertemperature operation causes the glue solution to become too thin, lose, oxidize, and be scrapped; Long term insulation without production is also burning money, and during intermittent production, it drops to insulation mode;
• Equipment leakageDripping from the joints of the glue pot, hose joints, and nozzle that are not tightly closed is not uncommon, with a few kilograms dripping in a day. Routine inspections can block it;
• Selection matchingLow solid content and highly permeable adhesive particles will be absorbed in large quantities on loose paper materials, and replacing them with targeted formulas can actually save adhesive.

Frequently Asked Questions

Q: Is it more cost-effective to switch to cheaper rubber granules?
Not necessarily. Low price adhesive has low content, high consumption, and requires a lot of rework, resulting in higher overall costs. Therefore, it should be compared based on the “cost of adhesive per unit product” rather than the “unit price per kilogram”.

Q: How do you know if your factory’s glue consumption is normal?
Record the weekly production and glue usage, calculate the glue consumption per book/box, and then compare it with industry reference values. Guangzhou Sunlife Trading can provide customers with free rubber consumption accounting and on-site diagnosis.

Summary: Reducing glue consumption does not rely on saving money, but on standardizing the glue quantity, temperature, equipment, and selection. The technical team of Sunlife hot melt adhesive can assist in implementing each item step by step.
