A Melt Unit’s (melt tank) main purpose is to melt packaged adhesives. Once melted, the unit pumps the substrate to a required location through heated hoses. These unit’s also serve as the temperature sensing and controlling center for the adhesive dispensing system. Valco Melton offers a wide range of piston and gear pump units to cover a variety of gluing industry applications. Each unit has been tailored to meet special temperature, tank size, and operation requirements.
Based on your application’s requirements, hot melt units should incorporate either a piston pump (pneumatic) or a gear pump. Piston pumps are primarily used in packaging applications where high adhesive output and pressure are needed. Gear pumps are more suitable for applications involving high viscosity adhesives and/or where there is a requirement for a very controlled and metered adhesive output.
