Meler MU Series High-Speed Precision Hot Melt Adhesive Bead Applicator – Configurable

Configurable Hot Melt Applicator for Precision Bead Application in High-Speed Packaging Lines

The Meler MU Series Hot Melt Adhesive Applicator is a pneumatically actuated applicator engineered for precise, high-speed bead application in demanding industrial environments. Designed for adhesive dots and continuous bead patterns, it delivers consistent output, fast response times, and stable adhesive flow under high production conditions.

The MU Series is fully configurable with single or multi-module setups and supports both air open–air close (AOAC) and air open–spring close (AOSC) actuation options to match specific application requirements. Its thermally stable design maintains uniform adhesive temperature up to the nozzle, ensuring consistent application quality at high speeds. Side-access construction provides convenient access to internal components, simplifying maintenance and reducing downtime.
