Building on the prototype it launched at K’98, Krauss-Maffei will commercially present an injection molding compounding (IMC) machine capable of in-line compounding directly upstream of an injection molding unit, with no intermediate cooling stage. One of the machines, a KM 1000-6100 IMC, will be producing a car tailgate at K 2001. The part will be produced in a back-compression process where a multi-layer film is inserted in the mold and glass-filled ABS compound is injected behind it to produce a finished part.
In place of a conventional plasticizing unit, an IMC machine has a special injection unit yoked with a co-rotating twin-screw extruder. In-line compounding makes it possible to tailor a formulation to precise specifications, and to avoid secondary re-heating and homogenizing of the compound.
