Leotech

What Leotech does

Leotech Rapid Prototyping und Werkzeugbau GmbH is a German owner-managed manufacturing services provider founded in 1998 and headquartered in Leonberg-H\u00f6fingen near Stuttgart. The company delivers an integrated, in-house portfolio spanning engineering/construction, rapid prototyping (SLA, SLS, 3D printing, 5-axis HSC CNC milling), metal casting via proprietary Vakuum-Differenzdruckguss, silicone vacuum casting with approximately 100 polyurethane resins, aluminum injection mold tool construction, and small-series injection molding. Its business model is quote-based and project-based: each engagement is individually priced by material, geometry, and volume, managed by a single point of contact from concept through serial production, with documented quality per DIN EN ISO 9001:2015 and PPAP/VDA/IMDS-compliant inspection for automotive and medical customers. Leotech serves enterprise engineering and product development teams in automotive, medical technology, mechanical and plant engineering, electrical engineering, and consumer goods, primarily in the DACH region, and reports more than 500 injection molds built and over 25 years of operating history.

The company's commercial positioning rests on a vertically integrated single-source workflow — from CAD/Moldflow engineering through additive manufacturing, in-house foundry, CNC, EDM, mold construction, and injection molding — under one roof, eliminating multi-vendor handoffs. Revenue streams derive from custom prototyping services (per-project), injection mold tool construction (per-tool, aluminum inserts only billed), injection molding production (per-part or per-batch for runs up to ~200,000 parts per tool), and standalone engineering/consulting services. Distribution is exclusively direct sales to enterprise buyers through the company website, phone, email, and trade fair engagement; no resellers, marketplaces, or productized self-serve channels are used.

Growth signals are indirect: research project participation (DigiAutoFab, AluL\u00e4ufer), a sponsorship with the University of Stuttgart Formula Student racing team, continued ISO 9001:2015 certification, and digital marketing on Google AdWords, LinkedIn, Facebook, and YouTube. The firm is bootstrapped, privately held by managing director Dipl.-Ing. Martin Bayer, and operates at a small scale (1-10 employees), with no disclosed funding, revenue, or geographic expansion beyond Germany.

Revenue model

1. Custom Prototyping Services: Leotech provides project-based custom manufacturing services across multiple technologies (SLA, SLS, CNC machining, silicone vacuum casting, metal casting) billed per project or part. Pricing is quote-based, determined by material, complexity, and production volume. This is the primary revenue driver.
2. Injection Molding Tool Construction: Leotech designs and builds custom aluminum injection molds (Spritzgusswerkzeuge), with customers charged for the aluminum form inserts and mold components. Tools are constructed in-house and delivered as part of an integrated offering. Revenue is project-based with per-tool pricing.
3. Injection Molding Production (Vor- und Kleinserien): Leotech operates an in-house injection molding technical center (Spritzgusstechnikum) producing pre-series and small-series plastic parts from thermoplastics. Customers pay per-part or per-batch fees for production runs, potentially with multi-year tooling amortization. Production volumes of up to 200,000 parts per tool are achievable.
4. Engineering and Consulting Services: Leotech offers engineering services including 3D CAD construction, design optimization, data preparation, manufacturing-ready design, tool design, injection molding simulation (Moldflow), and material selection consulting. These are billed as standalone services or bundled with prototyping/tooling projects.
