Applicator Improves Seal Quality


Manufacturing cost reduction is top of mind for packagers today, and converting from beads to adhesive dots is a simple way to reduce adhesive consumption by up to 50%, greatly reducing consumable expenses.


Meler’s micro-precision adhesive applicator uses advanced technology to accurately apply hot melt dots at high speed with top repeatability and long term reliability, eliminating barriers of converting from hot melt beads to dots. The system‘s microprocessor-controlled timer and driver combine immediate signal response with maximum device precision to rapidly apply 8,500 dots per minute. The high-speed solenoid valve ensures the most consistent operation and dosing accuracy. The applicator has a robust design to provide extended cycle life, and features for reduced energy consumption include insulated pneumatic tubes and “Cool-Touch” insulated applicator covers. An integrated filter keeps nozzles clean and is quickly changed without disassembling the hose or applicator. The compact applicator size ensures a simple conversion from standard adhesive heads.


For hot melt seals, the “start” of the bead is where the strength of the seal lies, and once broken, the seal integrity is compromised. Adhesive dots (or dashes) provide superior bonds by creating a new “start” at each dot, with the seal integrity intact until all the dots are broken. To create these bonds, equipment tolerances must be precise and Meler’s proven quality removes this factor from the equation. Meler systems are designed for repeatability, longevity, and reliability with extended cycle capability proven in production.
