The NX-1015 furnace model, with a 2,000 kg (4,400 lb.) capacity, is equipped with Nitreg® controlled nitriding and Nitreg®-C controlled nitrocarburizing, tailored for treating extrusion dies for aluminum profiles used in architectural applications. These technologies ensure precise control over uniform case depths and nitride/nitrocarburizing layer formation. This enhances the mechanical properties of the extrusion dies, resulting in a long service life and increased output per die, lowering the overall tooling costs for Beymetal. Additionally, the new installation contributes to more efficient use of production media and reduces electricity consumption.
For Marcin Stoklosa, manager of Technical Sales for the EMEA region at Nitrex, commented, “The need for extrusion companies to enhance tooling performance while prioritizing sustainability represents the future of the aluminum industry. Beymetal’s adoption of Nitrex nitriding and nitrocarburizing technologies serves as an example of this necessity. This transition harmonizes production with global sustainability initiatives for a more environmentally friendly future.”
As part of their strategic efforts to enhance forging capabilities, Topçesan recently invested in a compact batch-type furnace with a 1,200 kg capacity, designed for nitriding and nitrocarburizing forging dies. These dies are utilized in the production of engine parts, transmission components, and chassis parts for vehicle manufacturing, catering to automotive clients like BMW, Tofaş, Fiat, and ZF Group across Europe and Türkiye.

By integrating nitriding and nitrocarburizing processes into their operations, Topçesan aims to prolong the lifespan of their forging dies, increasing component production while reducing tooling costs. The NXK-812 compact batch-type furnace from Nitrex, a heat treat equipment supplier based in Canada, includes an ammonia dissociator; this will be essential for precision controlling nitriding potential, particularly when treating specific alloys that must align with AMS 2759/10 and AMS 2759/12 specifications.
Utku Inan, the Nitrex sales representative in Türkiye, commented, “This marks the first collaboration between Topçesan and Nitrex, and we’re truly excited to embark on this journey together. Our shared goal is to pursue operational excellence and maximize product potential within the forging and automotive supply chain industries.”
Topçesan is making a strategic investment that will not only enhance its in-house capabilities and cost efficiency but also contribute to a more efficient and sustainable future. According to Marcin Stoklosa, technical sales manager at Nitrex, “The operating software of the Nitrex system ensures optimal production media and utility consumption throughout the process, providing the customer with detailed analysis after each operation. This technological advancement underscores our commitment to customer satisfaction and operational efficiency, ensuring superior performance.”
Kuźnia Jawor, a company specializing in the production of hot forged and CNC machined components for the automotive, machinery, mining, and piping industries, has enhanced its manufacturing capabilities through the addition of an oil-hardening furnace and two nitriding furnaces from a supplier based in North America.
Kuźnia Jawor replaced their production line with an oil-hardening furnace and two outdated nitriding furnaces from Nitrex. The decision to upgrade was prompted by the need to eliminate outdated technology and address controls issues. The current production line has been designed using a Nitrex nitriding system and a vacuum hardening furnace.
Kuźnia Jawor leverages its in-house capabilities to design and manufacture forging tools, a crucial element of the production process. This is necessary for obtaining repeatable strength parameters in steel and ensuring their resistance to geometric changes or abrasive wear, factors that are addressed through heat treatment. The new equipment enables them to actively reduce CO emissions, decrease energy consumption, and more.
Nitrex furnace
The company’s forging and CNC processes are marked by meticulous precision, with dies initially undergoing treatment in the vacuum furnace before proceeding to the nitriding phase. This multi-step approach is essential for achieving a zero-white layer, effectively preventing surface cracking in the H11, H13, and WNL hot work steel dies subjected to high-pressure hammer forging. A crucial part of this initiative was the installation of a Nitrex horizontal-loading system, featuring the furnace model NXH-9912, a custom solution designed to facilitate the seamless automatic transfers of loads between operations.
The turnkey system is equipped with Nitreg® nitriding technology, which enhances the wear and corrosion resistance of treated tooling. This technology improves efficiency gains, leading to savings in process time and resources, including electricity and process gases. Furthermore, the system adheres to industry standard 2759/10 controlled nitriding, ensuring the highest quality and precision in the heat treating process.
Interestingly, Kuźnia Jawor is also engaged in an ongoing collaborative research and development project with a local university, exploring hybrid coatings that combine Nitreg® nitriding technology with PVD and CVD processes, with the aim of further enhancing tool performance.
Located in the southwestern region of Poland, Kuźnia Jawor is a provider of forged and CNC automotive parts within Poland and mining parts in international markets such as Czechia and Türkiye.

Marcin Stoklosa, manager of Technical Sales at Nitrex, who oversaw this endeavor, sums it up, “Kuźnia Jawor’s choice to partner with Nitrex was driven by the need to replace outdated equipment, modernize, and expand their production facility. The result? Improved quality, enhanced performance, and a stronger position in the forging industry.”
