Metal Seals: Nanotechnology and 3D Printing Expanding the Scope of the Industry

Key takeaways:

• Introduction
• Advancements in the metal seals market
• Latest product launches in the sector

Metal seals are highly engineered sealing solutions designed specifically to withstand harsh weather conditions, including high temperature, pressure, and moisture. Manufactured using robust metals and alloys like stainless steel, copper, aluminum, and Inconel, these solutions offer superior corrosion resistance, mechanical strength, thereby enhancing the overall durability of the contents stored in the sealed container and preventing their leakage. The expansion of the manufacturing and energy sectors has played a significant role in the growth of the metal seals market. In the last few years, the use of metal seals in nuclear reactors, oil & gas exploration equipment, semiconductor fabrication, aerospace, and automotive manufacturing industries has increased exponentially.

Innovations in metal seals generating new avenues for growth

Over the years, metal seals have evolved significantly owing to the changing requirements of manufacturing, power generation, and consumer electronics industries. In such a scenario, technological advancements and innovations in metal seals have contributed to the expansion of the industry. For example, the use of additive manufacturing techniques such as 3D printing has enabled companies to develop sealing components that are tailored to meet their clients’ demand. The shift toward such production methodologies has helped businesses to manufacture complex designs and geometries that were previously difficult to create using traditional mechanisms.

At the same time, advancements in material sciences have led to the development of resilient yet flexible materials that offer foolproof protection, along with enhanced durability and corrosion resistance. Many companies have designed products with additional layers of coatings and liners to improve their overall utility and efficiency in critical applications like nuclear reactors and oil & gas exploration. Moreover, the increasing investments in nanotechnology by leading private companies, research institutions, and engineering universities to develop specialized compounds for metal seals have boosted the revenue share of the industry.

Investment by major players boosting industry revenue

The metal seals industry accounted for $1.9 billion in 2024 and is predicted to gather a revenue share of $3.1 billion by 2034, rising at a CAGR of 4.7% during 2025-2034. Over the years, leading businesses in the industry have launched cutting-edge sealing components to cater to the changing needs of the industry and strengthen their position globally. For example, in April 2023, John Crane, a machine industry company, unveiled the Type SB2/SB2A USP seal, specifically developed for the paper & pulp and mining industries. The product has been manufactured to reduce water usage and bring down the overall power consumption of the industrial facility. The press release issued by the company highlighted that the new solution is aimed at minimizing the carbon emissions of these sectors, thus promoting environmental sustainability.

Similarly, in December 2024, Trelleborg, a Swedish multinational engineering company, announced the launch of Stefa®, a new series of radial shaft seals for mining, agriculture, and construction sectors. These components are globally compliant for various types of hydraulic motors and pumps, making them ideal for a wide range of operations and applications. Furthermore, they have been tested to withstand speeds up to 17 meters per second (MPS) and pressures up to 20 MPa. The product portfolio expansion is anticipated to boost the revenue share of the company in the coming period.

To summarize, the metal seals market held a significant market share in the last few years and is predicted to dominate in the coming period, owing to the surge in the utility of these innovative sealants in various end-use industries. The advent of nanotechnology and modern manufacturing processes such as 3D printing are expected to accelerate sectoral growth in the near future.
