Many customers consider the cost of purchasing glue, but not everyone considers the cost of using the wrong type of glue or whether you are using adhesive correctly. Glue is only a small part of a large-scale project, but if applied incorrectly, it may lead to production issues. Insufficient use of adhesive can lead to […]
The common quality problems of wireless binding hot melt adhesive mainly include page dropping, uneven back, broken book core, bubbles, and perforation at both ends of the book. They often appear on single or multiple banks, mainly due to the following reasons: 1、 Analysis of Page Dropping Reasons (1) The milling groove is too shallow […]
hot melt adhesiveWhen the glue pot has burnt particles, uneven glue dispensing, or impurities in the glue line, simply replacing the glue may not solve the problem. This article sorts out the troubleshooting sequence according to “glue pot status, temperature setting, shutdown habits, and glue supply path” to help reduce downtime and material waste in […]
