Concept Stream is Robatech’s solution for melting and feeding thermoplastic adhesives in granular form. According to the amount of adhesive required, the melter – equipped with “melt-on-demand” technology – can be used in a variety of applications. The gluing system is based on the proven Concept 5, with GreenLine technology. The heart of the Concept Stream is the small tank, designed for highest melting performance (8 kg/h). Melting performance and quantity can be exactly matched to the consumption using melt-on-demand technology. Thanks to its controlled adhesive flow, less burns occur in the system; residues in the tank are significantly reduced, and nozzle blockage is prevented to a large extent. Furthermore, the service life of the adhesive filter is extended and maintenance costs lowered. The very short heat-up time of 16 minutes to 160°C and the standby function ensure fast system availability. Fill level supervision, with run-empty protection stops the delivery of adhesive thus preventing greater losses due to poorly glued products or products without glue at all. Thanks to the CoolTouch insulation on tank, pump and glue distributor, energy savings of more than 20% can be achieved compared to the standard Concept. The filling area is separated from the hot area, thus ensuring safe manual filling and increasing operator safety.
