Alu Menziken Extrusion AG, New Nitrex System

“The Swiss corporation Alu Menziken Extrusion AG, a manufacturer of aluminum profiles and complex extrusion press products, chose a Nitrex nitrocarburizing system for its new state-of-the-art manufacturing facility on a greenfield site in northwestern Romania. Nitrex Metal delivered and installed a turnkey NX-815 nitrocarburizing system that incorporates the Nitreg®-C technology for treating aluminum extrusion dies. The pit furnace has overall chamber dimensions of 31.5” diameter by 59” high (800 x 1500 mm) with capacity optimized to nitrocarburize a 3300 lbs (1500 kg) load.

The process technology adapts to the application requirements to deliver improved performance of extrusion dies. Tailoring the application’s surface properties has a positive influence on performance metrics like throughput per run and number of runs per die, which, as a consequence, mitigates the cost of tooling. Alu Menziken also chose the Nitreg®-C technology to reduce the possibility of potential failures like premature washout and flaking that degrade the performance of dies.

“With a focus on the environment, Alu Menziken also sought to introduce eco-friendly technologies for all equipment at its greenfield facility. Not only is there a benefit of reduced process gas use with the Nitrex system, the integral high-efficiency neutralizer also helps comply with environmental regulations,” says Marcin Stoklosa, Nitrex European Project Manager. The modern factory situated in Mediesu Aurit, Satu Mare covers an area of 13 hectares and features the latest equipment for producing extrusions. Inaugurated this past November, the plant produces a range of profile products for aerospace and automotive companies, such as Audi, BMW, Bentley and Daimler, looking for lightweight aluminum solutions.
