The new, compactly designed Sonderhoff 3E dosing cell is economic, efficient and ecological. This mixing and dosing system for two components precisely processes liquid, medium and high-viscosity polyurethanes or other polymer reactive materials. Using the FIP (Formed-In-Place) technology, 2-component sealing foams, adhesives or potting compounds are directly applied onto the part, precisely and freely programmable, with the CNC-controlled mixing head.
