İnsu Teknik Transforms Gas Spring Production With Nitrex System

Summary

İnsu Teknik, a leader in the gas springs sector of the automotive industry, continues to pioneer innovation as a key supplier for after-market and OEMs, both in Türkiye and internationally, having successfully implemented a cutting-edge Nitrex system at its facility in Bursa, 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 Nitrex system, featuring a large-capacity pit furnace (model NX-1215), 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.

The Nitreg-C technology further increases surface hardness and fatigue resistance, while ONC yields a consistently even oxide layer, enhancing corrosion resistance and the overall aesthetic quality of the final products. Furthermore, the Nitrex system’s eco-friendly approach aligns with environmental standards by eliminating the production and disposal of hazardous waste.
 
Utku Inan, Nitrex’s local representative, commented, “İnsu Teknik sought metallurgical consultation for a sustainable and economically viable in-house solution. Having previously outsourced salt bath nitrocarburizing to a commercial heat treater, Insu Teknik found Nitrex to be the preferred choice due to its environmentally friendly technology and its capability to overcome the challenges associated with salt baths. This investment positions Insu Teknik for heightened control over their production, ensuring improved product quality and consistency.”
 
Marcin Stoklosa, technical sales manager–EMEA region at Nitrex, shared these insights: “The commissioning process was executed seamlessly, marking İnsu Teknik’s strategic shift towards greater control over their production processes. What sets this system apart is its versatility in meeting the specific requirements of various gas spring applications across various industries, including automotive, agriculture, machinery, marine, furniture, medical equipment and more. This move marks a pivotal moment in Insu Teknik’s journey toward sustainable manufacturing and greater customer satisfaction.”
