About KraussMaffei
KraussMaffei is a manufacturer specialized in plastics machinery headquartered in Munich. The company manufactures hydraulic and all-electric injection molding machines (clamping forces from 500 to 60,000 kN), metering and foaming systems of reaction technology for polyurethane as well as single-screw and twin-screw extruders for compounding, pipe, profile, film and foam extrusion. The portfolio is complemented by automation solutions such as linear robots, industrial robots, sprue pickers, gripper construction and automation of third-party machines as well as digital solutions for process monitoring and remote support. Materials processed include thermoplastics, thermosets, silicone, PVC, polyurethane, rubber, TPE as well as fiber-reinforced and powder-/ceramic-based feedstocks (MIM/CIM/PIM). Customers come, among others, from the automotive, electronics, medical technology, packaging, chemical, construction and refrigeration industries. Sales and service are provided worldwide; the headquarters is located in Munich-Allach with a planned relocation to Vaterstetten near Parsdorf.
