The Complex Parts Net Shaping innovation is an advanced Powder Metallurgy solution developed for the automotive industry to manufacture highly complex, multifunctional components as a single integrated part. Developed by Polmo Łomianki S.A. in collaboration with a leading automotive customer, the innovation addresses the growing need for lighter, stronger, more cost-effective, and more reliable vehicle components. Its primary objective is to replace assemblies consisting of multiple conventional parts with a single precision-engineered component that integrates several functions while maintaining high mechanical performance and production efficiency.

The core concept of the innovation is based on the ability of Powder Metallurgy to produce complex geometries directly during the pressing process. Instead of manufacturing several separate components and subsequently assembling them, multiple functions can be integrated into one part. A typical example is a component that combines both adjustment and locking functions within a single structure. This approach reduces the number of parts, simplifies assembly operations, and improves overall system reliability by eliminating potential failure points associated with joints, fasteners, or assembled interfaces.

One of the most important achievements of the project is the creation of components with a highly uniform microstructure and enhanced mechanical properties. Through optimized powder composition, precision pressing, sintering, and heat-treatment processes, the technology produces dense and mechanically robust parts capable of meeting stringent automotive performance and safety requirements. Compared with previous solutions, the innovation significantly improves torque resistance, increasing performance from 25 Nm to 65 Nm, while also achieving more than 100% improvement in material uniformity. These gains are particularly important in automotive applications where durability, reliability, and safety are critical.

The technical feasibility of the innovation was confirmed through an extensive development program involving multiple design iterations, prototype production, strength testing, and the creation of dedicated measurement and quality-control systems. Manufacturing relies on modern high-precision hydraulic presses and advanced inspection equipment to ensure dimensional accuracy and product consistency. The complete production process includes powder preparation, compaction, sintering, and heat treatment, resulting in components that fully satisfy customer specifications in terms of strength, quality, and functionality.

From an economic perspective, the innovation delivers substantial cost advantages over traditional manufacturing methods. By eliminating machining operations and reducing the number of production steps, the technology lowers material costs by approximately 33%, process costs by 40%, and energy consumption by around 30%. Tooling costs are reduced by approximately 27%, while overall production time decreases by nearly 40%. These savings stem primarily from near-net-shape manufacturing, which minimizes waste and reduces the need for secondary processing. As a result, the technology enhances the competitiveness of automotive component production while maintaining high quality and performance standards.

The innovation also contributes significantly to sustainability objectives. Conventional machining processes often generate large amounts of material waste and require considerable energy consumption. In contrast, Powder Metallurgy enables near-net-shape manufacturing, dramatically improving material utilization and reducing waste generation. The reduction in production operations further lowers energy requirements and associated CO₂ emissions. Additionally, the consolidation of multiple parts into a single component can reduce overall vehicle weight, contributing to lower fuel consumption and improved environmental performance throughout the vehicle lifecycle.

The technology has achieved Technology Readiness Level 9 (TRL 9), the highest level of technological maturity. The product has successfully passed customer validation, including strength and assembly testing, and is already being supplied in regular production volumes. This demonstrates that the innovation has moved beyond development and is fully operational under real manufacturing and application conditions.

Overall, the Complex Parts Net Shaping innovation illustrates the transformative potential of Powder Metallurgy in the automotive sector. By enabling the production of highly complex multifunctional components with superior mechanical properties, lower manufacturing costs, shorter production times, and reduced environmental impact, it provides a compelling example of how advanced PM technologies can improve both industrial efficiency and product performance.
