Nitrex Metal, St. Laurent, Canada, announces that it has delivered and installed a Nitrex nitrocarburizing system for a new state-of-the-art manufacturing facility on a greenfield site in northwestern Romania for the Swiss corporation Alu Menziken Extrusion AG, a manufacturer of aluminum profiles and complex extrusion press products.


The turnkey NX-815 nitrocarburizing system incorporates the Nitreg-C technology for treating aluminum extrusion dies. The pit furnace has overall chamber dimensions of 31.5 inches diameter by 59 inches high, with capacity optimized to nitrocarburize a 3300-pound load. Inaugurated this past November, the plant produces a range of profile products for aerospace and automotive companies such as Audi, BMW, Bentley, and Daimler.


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 such as 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 such as premature washout and flaking, which 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, but also the integral high-efficiency neutralizer also helps comply with environmental regulations,” says Marcin Stoklosa, Nitrex European Project Manager.
