Forging Provider Elevates In-House Heat Treat Department

/ ATMOSPHERE AIR FURNACES NEWS, AUTOMOTIVE HEAT TREAT, ENERGY HEAT TREAT NEWS, FEATURED NEWS, FORGING NEWS, HARDENING, HARDENING NEWS, NITRIDING NEWS

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Kuźnia Jawor replaced their production line with an oil-hardening furnace and two outdated nitriding furnaces from Nitrex. The decision to upgrade was prompted by the need to eliminate outdated technology and address controls issues.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.

As a first-time partner with Nitrex, İnsu Teknik has strategically invested in advanced heat treat technology, focusing on continuous improvement to enhance the quality of gas springs, operational efficiency, and environmental sustainability. Central to their decision was İnsu Teknik’s commitment to environmentally responsible manufacturing practices, which led them to seek a greener solution.

Commissioned in the last quarter of 2023, the system — featuring a large-capacity pit furnace — combines three key process technologies: Nitreg® controlled nitriding, Nitreg®-C controlled nitrocarburizing, and ONC® in-process post-oxidation. These technologies enhance the surface properties of gas spring rods, notably improving wear and corrosion resistance, and offering considerable operational advantages.

The system ensures uniform case depth and precisely managed nitride/nitrocarburizing layer formation, optimizing the mechanical properties of the gas spring rods. It minimizes part distortion — an advantage of operating at lower temperatures compared to salt bath nitrocarburizing — and eliminates the need for post-finishing operations due to the cleaner surface achieved through gas nitrocarburizing, thereby streamlining the manufacturing process.
