Hot-Melt Gluing Systems in Packaging: Complete Engineering Guide

Packaging line uptime relies directly on consistent temperature control and adhesive dispensing accuracy. Here are the core principles for eliminating glue nozzle clogs and unplanned maintenance.

1. Temperature Stability with Robatech Melters

Robatech Concept Diamond melters feature multi-zone PID heating that prevents adhesive thermal degradation and nozzle charring, preserving hot-melt viscosity.

2. Closed-Loop Granule Feeding: My Feeder Cube

Integrating the patented Glutec My Feeder Cube ensures optimal glue levels automatically. Closed-loop pneumatic suction prevents operator burns and keeps cardboard fibers out of the melt tank.

3. High-Speed Dot Dispensing & Adhesive Savings

Electronic application heads enable micro-dot intermittent patterns, cutting hot-melt consumption by up to 40% while preserving carton peel strength.

4. Technical Support and Spares from Merano

Frei GmbH delivers certified Robatech and Glutec original components, emergency 24/7 service, and tailored line integration across Northern Italy and Central Europe.
