300 participants in the International Forum of Krauss-Maffei

The machine of injection with preparation of compounds BMI combines the process of preparation of a double screw extruder, continued with the cyclical process of molding by injection. To this end the plasticizing of molding machine shall be replaced by injection by an extruder of synchronized rotation that introduces a molten mass of constant in a cylinder of injection or in an intermediate accumulator quality uninterrupted. All processes that are needed to transform a polymer with components of mixture, substances of reinforcement or padding in a homogeneous melt substances, occur in "heat". A constant functioning Gravimetric dosing unit guarantees the homogeneity of the composition of the material. The excellent characteristics of the innovative technology of production are: - homogeneous preparation of the molten mass of plastic - inlay careful filling and reinforcement - capacity of extremely high plasticizing substances.
With lectures informed by own employees, a general presentation on the theme "PP compounds reinforced with natural fibers" of Hans-G. Fritz, KT Stuttgart, as well as with speakers from the industry of materials and technology of dosing (BASF)(, DOW, Minelco, Naintsch Mineralwerke and Colortronic), the event offered a high information density. With numerous examples of calculation, was presented the savings potential of this technique with the use of the conventional technique. The final presentation was offered by Philippe Dumazet of Faurecia, France, one of the first users of IMC systems and leading manufacturer of components for the automotive industry. From his point of view, the new technology offers a wide range of perspectives in the fields of integration of functions, high transduction of strength with low weight, flexibility in the selection of the material, possibility of reuse, design freedomthermal resistance, sound insulation and cost reduction. Employment possibilities reside mainly in the manufacture of bumper mounts, mounts for panels of instruments, wall and floor coverings, integrated door coverings, integrated frameworks for seats, walls firewall and supports front.

On a machine of injection with preparation of composite 2700 KM ICM, were manufactured coatings for bumpers according to a concept of material of Borealis, Linz. It was an open compound of R-TPO (types of reactors of high shock resistance PP), mixture of high-performance, talc and black mixture. This composition of materials is currently a material used in the series. Because the collaboration of Krauss-Maffei and Borealis has just begun, there are still comparisons of materials for finished products. On a second machine for injection molding with preparation of BMI compounds of the type 1300 KM BMI, was the manufacture of a front support, carried out with a package of PP specially developed by Dow and glass fiber cables. The development of the technique presented to release to the market was supported by Dow Automotive, Schwalbach, through an extensive series of trials. As an alternative to the balls of PP fibreglass for the usual injection moulding, the Dow Automotive company created types of PP for the process of preparation of compounds in line with equivalent features glass fibers from the technical point of view and that provide the desired saving of costs.
Points of information in the technical lab about topics and materials related to IMC completed the information offer of the event. Arose, including surfaces Decoform technique, the technique of several components, the technique of foaming (inter alia, MuCell technique and technique of water injection) as well as the LFI-PUR technology.
With the innovative technology BMI House of Krauss-Maffei systems presented solutions, among other things, for the next cycles of cars to a very large Forum. Technical laboratory in Munich, exist from this very moment three moulding machines for injection with preparation of BMI compounds with a magnitudes of 4,200, 13,000 and 27,000 kN clamping force, respectively, available to those interested in doing.
