Sintered structural parts in the automotive industry: from niche to necessity

The fundamental shift in vehicle design

The applications of Powder Metallurgy in the automobile industry are no longer a 'niche' alternative. Industry analysis indicates they are now a fundamental requirement for high-performance, lightweight, and cost-effective vehicles. This represents a clear evolution in design philosophy. A significant consolidation in the supply base shows this industry maturity. On Tuesday, February 3, 2026, Dauch Corporation acquired Dowlais Group plc and its subsidiaries, including GKN Powder Metallurgy.

Processes and components in production

Manufacturing these parts involves several established methods. The primary processes are Press-Sintering PM, Metal Injection Molding (MIM), and Hot Isostatic Pressing. Metal powder 3D printing, including binder jetting and SLM, is also part of the toolkit. These methods produce a wide array of components. Common part types include gears, oil-impregnated bearings, cams, and sprockets. More complex assemblies like oil pump rotors, VVT rollers, and planetary gear rings are also manufactured this way.

Drivers of adoption and future demand

Automotive OEMs and Tier suppliers adopt this technology for concrete reasons. It helps reduce waste, improve part reliability, and maintain cost stability in a demanding market. The technology combines advanced materials with efficient near-net-shape manufacturing. This is particularly valuable as vehicle architectures change. The demand for these components is expected to intensify through 2026. This is partly driven by the growth of electric vehicles, which require precision components for silent motors and other systems.
