Full-service commercial heat treating solutions provider Akademi Metalurji incorporated a turnkey nitriding installation to save on process gases and production time, and also process wider-dimensioned parts.
The project includes a mid-sized pit-type furnace, advanced controls, three process technologies, and accelerated cooling. The latter add-on equipment will help reduce cycle times, optimize production between batches, and run more cycles.
This new system allows the company to overcome efficiency and quality challenges they faced at the Gebze, Turkey, facility; the prior system consumed excessive amounts of process gases and yielded inconsistent nitriding results. Nitrex, a Canada-based company with international locations, provided the NX-1015 pit furnace, which offers an effective work zone of 39” d x 59” h (1000 x 1500 mm) and a load capacity of 4400 lbs. (2000 kg). The supplied library of Nitreg®-based recipes is tailored to meet different application requirements, resulting in a hardened surface that is highly wear-resistant, particularly useful for applications like machinery components, tooling, dies, and molds, where Akademi Metalurji specializes.
The system was successfully installed and commenced operations in April 2023.

A manufacturer in Poland turns to in-house heat treating capabilities rather than outsourcing its nitriding for stainless steel power generation parts. Steam turbine components will now be processed at the facility in Elbląg as a result of funding help from a government program part of the European Union.
P.W.P.T. POSTEOR Sp. z o. omade the decision to stop outsourcing to commercial heat treaters its steam turbine pieces to bring the nitriding in house. The NX series furnace, model NX-620 will streamline production of these parts with its automated capabilities. The pit type furnace from NITREXmeets requirement for nitriding, nitrocarburizing, and in-process oxidation. “The turnkey system also includes remote access software, an INS neutralizer for a clean and environment-friendly process, and a custom HMI for the end-user," describes Marcin Stokłosa, project manager at NITREX. "It is entirely automated, requiring little operator attendance or involvement."
POSTEOR hopes to reduce the challenges it was facing in outsourcing the components. With the nitriding furnace the company will have more positive control of the end results.

The Capi Group has boosted its nitriding/nitrocarburizing capacity with two heat treat furnaces to keep up with the rise in production and new orders from the industrial and automotive sectors.
The Italian gear manufacturer's order of Nitrex's large-capacity nitriding systems "is a continuation of our collaboration, and we look forward to strengthening this partnership further,” says Marcin Stokłosa, project manager at Nitrex.
The Capi Group owns four pit-type nitriding/nitrocarburizing furnaces of the same model type and larger size, which consist of Nitreg® and Nitreg®-C technologies, +/-3°C temperature homogeneity in the retort, and eco-friendly IN-500 exhaust neutralizer to support a clean and green operation.
The new Nitrex furnaces, which comply with the Aerospace Material Specifications (AMS) 2750 for pyrometry and 2759/10 for controlled nitriding, are integrated into the existing production line and connected to a closed-loop water cooling system. The latter is an environmentally friendly feature that recirculates a steady supply of cooling water to cool furnace elements.
The new systems have been operational for a few months.

A global aluminum and energy company, Hydro Extrusion Norway, recently received a horizontal nitriding system, configured to replace an old decommissioned furnace
This latest delivery by Nitrex is the only one of its kind at Hydro facilities globally; the rest are pit-type furnaces. The nitriding equipment for Hydro Extrusion Norway in Magnor, Norway will integrate with the existing infrastructure of the plant as well as fit in the specific floor space allocation.
"Before placing the order, Hydro did its due diligence – visiting extrusion facilities with Nitrex equipment to get user opinions on the solution including the technology, die performance, extruded profile quality, and our support services," adds Marcin Stokłosa, project manager at Nitrex. "Moreover, the test trials produced very good results."
Qatar Aluminium Extrusion Co. (Qalex) recently received a nitriding system. The aluminum profiles manufacturer wanted to equip a second extrusion plant with an independent nitriding furnace to save on handling, processing time, and costs associated with having to transport extrusion dies back and forth from its first factory for nitriding work.
The client chose a compact system from Nitrex, an international provider in surface treatment with North American locations. The model NXK-1015 furnace is equipped with process technology designed for nitriding extrusion dies.
Marcin Stokłosa, project manager at Nitrex Poland, said, "Qalex was . . . very pleased with our technical support and spare parts accessibility. What they ordered is an exact copy of the first Nitrex installation – an identical configuration with the same furnace model, size and process technology."
Installation and startup were completed in January 2022.

In order to meet increasing market demand, a global auto manufacturer is including the installation of a second automated nitriding cell to help expand production capacity of automotive parts. The capital equipment will allow the client to bring the production process in-house for greater control, flexibility, and enhanced effectiveness.
This is the client's third order from Nitrex and second nitriding cell installation in this phase. Nitrex will undertake almost all aspects of the cell for 24/7 lights-out manufacturing: furnaces, charge cars, loading/unloading and magazine tables, and auxiliary equipment (e.g., atmosphere neutralizer, water cooling stations, charge cooling station, etc.). All equipment will be connected to the Protherm 9800 automation platform for automatic handling and processing, which improves workflow efficiency, process reliability, furnace utilization, work order tracking, and real-time performance metrics.For this latest order, six continuous flow-through nitriding systems, furnace model NXHL-910512, were ordered to create the fully automated cell, which is responsible for automatic loading/unloading, processing, and transport. Delivery is planned for August 2022, and the cell should start operating in autumn.
"This chain of events helps increase the plant’s efficiency and productivity: the cell selects the furnaces in which it is possible to place consecutive batches or delivers the batches to several furnaces to process. Since charges are transferred to a cooling station outside the furnace, the furnace can continuously process batches without affecting the workflow and productivity," adds Nikola Dzepina, the executive of International Accounts. "This is a huge process simplification for the furnace operator and enables an automatic and autonomous operation of the area of the plant that controls surface treatment, allowing to increase productivity but also to maintain the repeatability of results."
