By optimizing the EVA hot melt adhesive, the production time and unnecessary equipment maintenance costs during the bonding process of the product have been significantly reduced.
The adhesive clogged by “carbon” (carbon deposits) has caused a considerable amount of production downtime and maintenance costs on the production line. In the hot melt adhesive industry, there is a client who achieved their operational budget target by eliminating the production bottleneck caused by their previous adhesives.
When using traditional hot melt adhesives, the process adhesive machine system is more likely to carbonize over time, even with diligent preventive maintenance. When carbon deposits reach a critical stage, they will clog the gluing machine production line, leading to unsealed packaging and production line shutdown.
Three major methods to significantly reduce the probability of carbonization or eliminate carbonization by choosing hot melt adhesives and hot melt application equipment.
1. Use hot melt adhesives with low application temperatures to reduce heat exposure.
2. Use high-quality and suitable application adhesives that remain stable under typical thermal exposure.
3. Use on-demand melting hot melt application equipment to limit heat exposure.
Quick print shops often encounter orders with small quantities, multiple sheets, multiple covers, and tight delivery times. A more practical approach than searching for “universal binding glue” is to establish a process for confirmation, trial assembly, and parameter retention before changing orders. This article explains how to reduce rework from daily order taking scenarios. Core […]
Proper preparation and preheating are required when using hot melt adhesive for books and periodicals to ensure smooth operation. The goal is to achieve a good bonding effect. When using EVA hot melt adhesive, the first step is to master the preparation process such as preheating and temperature control before use. 1. Add glue It […]
The quality of book binding often depends not only on the equipment and paper, but also on the binding adhesive. If a book experiences problems such as page dropping, glue peeling, stiff spine, uneven flipping, and low-temperature brittleness, it is often related to the choice of binding glue, glue temperature, paper type, and process compatibility. […]
What are the carbides in the glue pot? Why is it necessary to clean up? hot melt adhesive pelletsHeating in the glue pot for a long time will cause the resin and thickening agent to slowly decompose, forming black carbides that deposit on the bottom of the pot and the wall of the rubber tube. […]
