Revenue model

1. Precision Parts Manufacturing: Manufacturing of custom precision parts from prototypes through series production. Revenue is project-based, typically quoted per component or job, with pricing influenced by complexity, materials, quantities, and documentation requirements. Services include CNC milling, turning, grinding, and EDM processing.
2. Toolmaking Services: Design, manufacturing, and maintenance of precision molds, pressing tools, punching tools, forming tools, and progressive tools for series production. Revenue generated through tool design projects, tool manufacturing, and ongoing maintenance/spare parts services.
3. OEM Assembly Solutions: Extended workbench model providing complete OEM assemblies and system assemblies including development, industrialisation, procurement, manufacturing, assembly, testing, and logistics. Revenue derived from full-service assembly contracts with series logistics (Kanban, framework agreements, buffer stocks).

Functional benefit

Products and services

• Precision Parts Manufacturing (Präzisionsteilefertigung) µ-accurate custom precision parts manufacturing using state-of-the-art CNC technology including milling, turning, grinding, and eroding, producing miniature and complex parts as well as medium and large milled/turned components with complete traceability and ISO 9001 certification for industrial OEMs and Tier 1 suppliers.
• Prototype Production (Prototypenfertigung) Rapid implementation of functional prototypes using 3D milling and simultaneous 5-axis milling with short lead times and high dimensional accuracy, including DFM checks, reverse engineering, 100% measurement, and documentation to enable seamless validation into zero-series production for R&D and product development teams.
• Series Production 24/7 (Serienfertigung 24/7) Automated 5-axis series production with continuous shift operation producing ready-to-install components from small series to established series, offering reproducible quality, reliable delivery dates, and flexible quantities from prototypes to medium-sized series for industrial customers.
• Tool & Spare Parts Service (Werkzeugbau & Ersatzteilservice) Toolmaking services including mould making, pressing tools, punching tools, forming tools, fine blanking tools, press hardening and hot forming tools, blow moulds, and progressive tools, plus spare parts manufacturing and maintenance services for tools throughout their lifecycle.
• OEM Solutions (OEM-Lösungen) Complete OEM assembly and system assembly solutions acting as an extended workbench, providing development, industrialization, procurement, manufacturing, assembly, testing, and logistics from a single source, including sensor housings, optical holders, galvo/mirror holders, workpiece carriers, UHV components, and cleanroom-compatible assemblies.
• Wire and Die-Sinking Erosion (Draht- und Senkerodieren) Electrical discharge machining (EDM) services including wire erosion and die-sinking erosion for maximum precision, used for complex geometries, fine structures, hard materials, intricate contours, and applications where traditional machining cannot achieve the required precision.
