Nanotechnology: Varvel’s contribution to the NewSkin project

Material innovation is undoubtedly one of the most exciting challenges in modern manufacturing and nanotechnology stands out as one of the most groundbreaking advancements in materials science and engineering. This specialized field operates on a nanometric scale, meaning at the level of billionths of a meter, allowing material properties to be modified in ways that traditional technologies cannot achieve.

Thanks to their ability to manipulate matter at an atomic and molecular level, nanotechnologies enable the creation of materials with enhanced characteristics, such as greater resistance to wear and corrosion, self-repairing properties, reduced friction and improved thermal conductivity. These advancements are already being applied in numerous industries, from electronics to medicine, to manufacturing and are revolutionizing the design and production of high-performance mechanical components, such as gearboxes.

In this context, NewSkin, an ambitious European project, takes shape. Its goal is to establish an Open Innovation Test Bed (OITB) that facilitates the adoption of nano-structured materials in industrial processes. NewSkin provides businesses with a cutting-edge infrastructure to test and validate nanotechnology solutions applied across various sectors, from industrial goods to consumer products. Launched in 2022 and structured into nine Work Packages (WP), the project aims to build a network of services and laboratories dedicated to developing innovative materials with a strong emphasis on sustainability and production efficiency.

Among the companies participating in the initiative is Varvel, which has been leveraging its extensive expertise in power transmission to contribute to the development of nanotechnology-enhanced gearboxes.

The impact of nanotechnology on gearbox durability and performance

Gearboxes are critical across multiple industrial sectors, including packaging, automation and renewable energy. However, wear, friction and corrosion remain key factors affecting their performance and lifespan.

Nanotechnology offers tangible solutions to overcome these limitations. Nano-structured materials enable the creation of more resilient surfaces, reducing friction and improving heat dissipation. Such benefit results in higher energy efficiency and a decreased need for maintenance.

In summary:

• Nanotechnological coatings enhance wear and corrosion resistance, extending the operational life of gearboxes.
• Advanced materials allow for weight reduction without compromising structural strength, thereby improving overall performance.

Beyond optimizing gearbox operation, these innovations also contribute to greater industry sustainability, reducing material consumption and environmental impact.

Varvel’s role in the NewSkin European project

Founded in 1955, Varvel is a benchmark in the gearbox and gearmotor industry, with a strong international presence. The company has always embraced technological innovation as a strategic driver, continuously investing in research and development.

Participation in the NewSkin project represents a valuable opportunity for Varvel to test cutting-edge nanotechnology applications for its gearboxes. The company collaborates with leading research institutes and industrial partners to develop advanced coatings that significantly improve mechanical component resistance and efficiency.

As part of the project, Varvel has focused on testing nanotechnology solutions for its gearboxes, aiming to enhance operational efficiency and component durability. Specifically, the company directed its research toward two key areas:

• Anti-friction nano-coatings: one of the primary challenges in gearbox design is minimizing energy loss caused by friction between moving surfaces. Nanotechnological coatings alter the microstructure of component surfaces, creating an ultra-resistant barrier that significantly reduces energy dissipation. Such an advantage improves overall performance and reduces wear, extending the lifespan of the components and lowering maintenance needs.
• Innovative nanotechnology-based materials: Varvel’s research has also focused on developing advanced materials that combine lightness with mechanical strength. Nano-engineered structures enable the production of components with greater structural density and optimized stress distribution, ensuring consistent performance even under harsh operating conditions. This development is particularly beneficial for high-intensity industrial applications, where weight reduction contributes to lower energy consumption and enhanced efficiency throughout the transmission system.

These technological advancements align seamlessly with Varvel’s long-term growth strategy to deliver increasingly efficient and cutting-edge solutions. The company aims to integrate these nanotechnological innovations into its manufacturing processes, making its gearboxes more high-performing and sustainable, fully meeting the demands of an evolving global market.

The future potential of nanotechnology for Varvel

Integrating nanotechnology into gearbox and gearmotor manufacturing takes a significant step toward a more efficient and sustainable industry. The NewSkin project allows Varvel to experiment with cutting-edge solutions that could redefine industry standards.

Looking ahead, the company remains committed to investing in innovation, focusing on expanding the application of nanotechnology across its product line. Collaborating with European partners and leveraging advanced research programs such as NewSkin will allow Varvel to solidify its leadership in power transmission technology, offering customers increasingly high-performing and reliable solutions.

Nanotechnology is still in its early stages of industrial application, but Varvel is fully prepared to seize the opportunities this growing field offers.
