This expansion follows a long-standing collaboration, which began in October 2004 with the commissioning of Special Springs‘ first Nitrex nitriding turnkey system and continues with the installation of an NXK series furnace in July 2024.

The springs manufacturer installed the compact NXK-812 furnace, which incorporates the heat treat technologies Nitreg and ONC, to accommodate increased capacity and optimize production efficiency. The system has a load capacity of 1,200 kg (2,600 lbs); the two furnaces work alongside each other, utilizing interchangeable material handling equipment to ensure continuity and efficiency in their production process.

“[Special Springs’] decision to expand with a second Nitrex system highlights the strength of our solutions and the trust we’ve built over the years. We look forward to seeing future advancements supporting advanced gas springs exemplifies the synergy achieved through strategic collaboration, advanced heat treat technologies, and exceptional support,” said Marcin Stoklosa, technical sales manager of EMEA region at Nitrex.

Lenox has opted to bring operations in-house (in Bulgaria) to improve die reliability through more stringent quality control. “Previously, the company sent extrusion dies for salt bath nitriding and gas nitriding," explains Marcin Stokłosa, project manager at Nitrex. "Lenox Group experimented with various case hardening technologies in search of the best one, the results of which would be repeatable and consistent with their expectations."

The N-EXT 412 is a compact-size Nitrex gas nitriding furnace for low volume quantities. This turnkey nitriding system is built on a self-contained platform that includes the furnace, control system with Nitreg® technology, and an exhaust neutralizer for clean and green processing. With a temperature distribution of +/-5°C, it is suitable for nitriding H11 and H13 extrusion dies.
