Fertigungsgerechte

Fertigungsgerechte Gestaltung describes a design approach in engineering and product development that prioritizes manufacturability. The aim is to create products that can be produced reliably, at reasonable cost, and with efficient processes by integrating production constraints into the early design phase. In German-language usage it is closely related to design for manufacturability (DFM) and design for assembly (DFA).

Core considerations include the overall part count, standardization of components, and the choice of materials and manufacturing processes. Tolerances and geometric features should reflect what the chosen processes can reliably achieve. The goal is to enable smooth production, reduce setup times, and facilitate automation where appropriate, while preserving the required function and quality.

Implementation typically involves cross-functional collaboration between development, manufacturing, and quality teams. Methods include DFMA analyses, process-aware design guidelines, tolerance stack-ups, and early cost estimation. Tools such as computer-aided manufacturing simulations and manufacturability reviews are used to identify potential risks and cost drivers before production starts.

Common guidelines and examples include using standard fasteners and components, minimizing part variety, reducing complex geometries, avoiding undercuts, ensuring uniform wall thickness where possible, and selecting features that are easy to machine, cast, or form. For sheet metal, considerations address bending allowances and reliefs; for plastics, wall thickness and rib design matter.

Benefits of fertigungsgerechte Gestaltung include lower production costs, shorter lead times, higher quality, easier automation, and improved yield. Limitations involve the need for early and ongoing cross-functional input and potential trade-offs between cost, function, aesthetics, and performance.
