Siebenwurst

What Siebenwurst does

Siebenwurst (legally Christian Karl Siebenwurst GmbH & Co. KG Modellbau & Formenbau) is a German family-owned industrial tool and mould maker founded in 1897 and headquartered in Dietfurt, Bavaria. The company designs and manufactures complex models and moulds for injection moulding, die casting, and compression moulding of three-dimensional plastic and aluminum components, with a particular focus on lightweight construction for automotive applications. It serves primarily automotive OEMs and Tier 1 suppliers, which account for an estimated 85% of revenue, with secondary exposure to household appliances and environmental technology customers.

The company's offering covers the full process chain from design models, cubings, and prototypes through mould production, try-out and sampling, mechanical processing, small-series production, and on-site maintenance under the registered "Tool Doctors" service brand. It differentiates through proprietary process technologies including FIT-Hybrid (combining organosheet forming with injection moulding in a single tool for fiber-reinforced plastic hollow structures), direct processing of dry fiber preforms, and 3-D hybrid construction technology. These have been recognized through three Werkzeugbauer des Jahres awards (2009, 2012, 2018), a JEC Innovation Award (2011), and a Top 100 Innovator designation (2010). The company operates from approximately 14 locations across Germany, Poland, China, Mexico, and the United States, with the recent Dietfurt assembly hall expansion adding roughly 2,500 m² and 80-tonne crane capacity.

Revenue is generated through custom B2B contracts for tool and mould manufacturing, supplemented by professional services from subsidiaries including Siebenwurst Consulting & Services GmbH (engineering consulting), SOLID solutions in design GmbH (majority-owned product development, acquired 2016), erocut Funkenerosions GmbH (wire erosion), and CAD/CAM Solution. The business is sales-led with enterprise field sales targeting automotive OEMs; Siebenwurst reported €85M of revenue in 2017 with 700+ employees, and has stated a medium-term target of €100M revenue and 1,000 employees. The 2021 partnership with Alba tooling & engineering GmbH extended the portfolio into machine and plant engineering, and the HyFiVe research project targets battery system housings for electrified mobility.

Broad incumbents

• Arburg GmbH + Co KG: German manufacturer of injection moulding machines and turnkey systems with strong automotive and technical moulding presence. Comparable to Siebenwurst as a German plastics-processing incumbent operating in the same OEM and Tier-1 supply chain.
• Wittmann Battenfeld: Austrian/German maker of injection moulding machines, robots, and auxiliaries for plastics processors. Comparable as a broad-line incumbent supplying the same automotive and industrial moulders that Siebenwurst builds tools for.
• Husky Injection Molding Systems: Canadian global supplier of injection moulding equipment, hot runners, and complete mould systems for packaging, beverage, and automotive. Comparable to Siebenwurst as a broader incumbent selling integrated moulding solutions rather than specialised German toolmaking services.
• KraussMaffei Group: German manufacturer of injection moulding machinery, extrusion, and reaction process machinery serving automotive, packaging, and construction. Comparable as a broader industrial incumbent whose moulding machine and tooling ecosystem overlaps Siebenwurst's automotive customer base.

Direct peers

• DME Company: Global supplier of mould components, hot runner systems, and standard mould base products serving plastics injection moulders. Comparable because it competes with Siebenwurst for the toolmaker's wallet within the same automotive and industrial moulding end markets.
• Meusburger Georg GmbH & Co KG: Austrian mould and die standards maker offering standardised catalogue parts (mould bases, slides, ejector pins) and increasingly custom tooling. Closely comparable to Siebenwurst's mould-making and model-construction services for plastics and die-casting customers.
• Schöttli AG: Swiss precision mould maker for medical, pharmaceutical, and high-performance technical parts with mould-construction heritage. Comparable for its high-precision mould-making capability and project-based sales motion to industrial/automotive customers.
• EWIKON Heißkanalsysteme GmbH: German specialist in hot runner systems for injection moulding, serving automotive, packaging, and technical moulders. Directly comparable as a precision German-engineered tooling component supplier within the same automotive mould-making ecosystem.
• Mold-Masters (Meltor / Milacron): Canadian-based hot runner and temperature-control technology supplier to moulders globally. Comparable to Siebenwurst's mould-production offering and increasingly relevant as hot runner systems integrate with lightweight composite tool designs.
