NEWALU

NEWALU GmbH has a range of automotive manufacturers as customers, for whom we produce seven days a week in a multi-shift system. We treat parts like roofs, floors, front and rear vehicle ends, wings and engines before manufacturing, using the polymer quenching process we developed.

This innovative casting process with subsequent heat treatment allows even complex, multifunctional components to be processed, which previously had to be assembled from separate individual components in cost-intensive methods. The polymer quenching process therefore not only reduces residual tension in the component, it also saves costs.

With electric mobility, the German automotive industry is facing one of the biggest structural changes in its history. "For lightweight aluminum constructions, the change to e-mobility is an absolute market of future" says Stefan Matthaei, Managing Director Strategy at NEWALU. The volume of engine blocks to be treated will tend to increase at first, because combustion engines will be joined by hybrid units with both engine blocks and electrical components. Purely electric powertrain components show that an electric motor with integrated control and cooling has approximately the same volume and mass of aluminum as a normal engine block. "Whether we heat treat an electric motor block with integrated controls or a combustion engine block with four cylinders is irrelevant to our business model," says Matthaei. The key words in this context are battery trays or battery containers. To realize their complex structures with high crash performance requirements, die-cast aluminum is used almost exclusively. "These parts are really exciting because they are in no way inferior to the strength and stiffness requirements of structural body parts. These are very large parts, about 1.20 m long, up to 80 cm wide and  cm deep. The right heat treatment know-how is particularly important here," says Martin Volpers Managing Director of operations.
