DUESSELDORF, Germany—Sonderhoff, the machinery company that is part of Henkel, has developed a new dosing cell for a large number of CASE applications.
The Sonderhoff 3E dosing cell makes it possible to apply two-component polyurethane systems for adhesives, sealing foams or potting compounds directly to parts. It has a typical repeating accuracy of 1 millimeter.
At the heart of the machine is a linear robot. This controls an MK 425 mixing head. The mixing head has a traversing range of 2.5×1.25×0.25m, and it can produce between 0.5 and 5 g/s of polyurethane. The mixing head can handle ratios between 10:1 to 1:2 in infinite steps. This allows approximately 80 percent of the current applications for this type of machinery to be covered, the company claimed. The machine has a maximum traverse speed of 15 meters per minute.
The 3E system is transported and delivered as a completely assembled system in a 20-foot container. Sonderhoff said that it only needs to be set at its destination, and connected to power, compressed air and water supply. Then, when the conditioned material in its pressure tanks is ready, so is the machine.
