Installment 2: Navigating Sustainability and Technical Innovations

Installment 2 delves into the transformative landscape of heat treatment within the automotive industry. Building upon insights from Jason Orosz, President of Global Heat Treating Services at Nitrex, in the first installment, this continuation highlights the industry-wide shift towards sustainability and the growing significance of technical partnerships and Artificial Intelligence. Join us as Jason discusses how heat treatment is evolving to shape the future of the automotive industry.

4. Sustainability Driving Industry-wide Change

Over the decades, consumer expectations for consistently higher standards in quality, performance, and cost have driven OEMs and car manufacturers to demand enhanced processes from their suppliers. For heat treaters, this translates into the need for tighter dimensional tolerances and more exacting metallurgical requirements, contributing to the continuous pursuit of excellence.

Today, a notable shift is occurring, placing a growing emphasis on sustainability across the supply chain. While suppliers are yet to establish specific targets, Nitrex observes a commitment to improving environmental footprints, suggesting the forthcoming establishment of precise goals as the industry defines a baseline for common surface treatments.

While eco-friendly processes like nitriding and nitrocarburizing lead to enhanced repeatability and sustainability, this next-generation impetus has fostered further advancements in process control, cleanliness, traceability, and efficiency. The latest hardware and software innovations enable more resource-efficient use of process gases and energy, minimizing environmental impact. The enduring commitment to quality, now intertwined with a growing emphasis on sustainability, is shaping the manufacturing landscape of automotive production.

5. Strategic Decision-making: Outsourcing vs. In-house Capabilities

In the evolving landscape of the automotive industry, OEMs and component manufacturers grapple with whether to outsource or maintain in-house control. During uncertain periods, the prevailing wisdom for many is to retain minimal in-house capability.

Navigating the balance between outsourcing heat treatment work and investing in in-house equipment is a delicate dance. Nitrex observes a growing demand for heat treatment equipment, particularly in brake rotors, where the appeal of maintaining control over processes during the deployment of new approaches is evident. However, as specific processes become standardized across components, a shift towards outsourcing emerges. This strategic move enables manufacturers to redirect their focus to unique expertise, often centered around component design. Moreover, when space constraints become pivotal, manufacturers concentrate on their core strengths and outsource other surface treatment work. Given the significant investment in deploying equipment, manufacturers lean towards seeking third-party assistance, especially in well-established markets.

6. Technical Partnerships and the Dominance of Artificial Intelligence

In the dynamic automotive industry, collaborations stand out as a cornerstone, with parts suppliers strategically forming technical partnerships with major tier-1 car manufacturers. These partnerships grant part suppliers increased influence over component design and production. Nitrex recognizes the vital role of these collaborations, acting as pivotal bridges to address the shortage of skilled professionals with metallurgical data expertise in heat treatment.

This trend is also propelling the industry towards embracing artificial intelligence and machine learning, as with Nitrex’s substantial investments in QMULUS. This new IIoT platform utilizes machine learning and cloud computing to analyze past heat treatment recipes, constructing a predictive model for achieving quality outcomes. It can be connected to all the key treatment furnaces and supporting equipment, ensuring strict compliance with regulatory frameworks and allowing artificial intelligence notifications for any deviations from predetermined outcomes.

Nitrex’s next evolutionary step in digitalization involves optimizing data utilization in machine learning and cloud computing, pushing the boundaries of sustainability and repeatability. Analyzing and monitoring process control with these tools will drive the next waves of improvements and efficiencies in the industry and help lower the carbon footprint associated with heat and surface treatments.
