In contrast to other hot melt systems, the energy in the PowerMelt extruder is generated entirely by the drive system. This eliminates the need for cleaning, even after prolonged operation.
The innovative screw geometry guarantees consistent melting of high-temperature adhesive granules, such as those required by a wide slot coater. Granules are heated to melting temperature by the friction within the extruder. The melt temperatures are achieved automatically, regardless of the nature of the adhesive. Adhesive does not collect in the extruder because of the continual screw action. Powermelt can be retrofitted to all machines and for all applications.
