STØTEK

What STØTEK does

STØTEK A/S is a privately held Danish manufacturer, founded in 1987 and headquartered in Vojens, Denmark, that designs and builds industrial aluminum melting, holding, and dosing furnaces for the global automotive industry. Its product portfolio spans dosing furnaces (Dosotherm® DTI immersion-heated and DTE radiant-heated models, AMED electric and AMGD gas-fired crucible dosing units), crucible furnaces (AME/AMET electric and AMG/AMGT gas-fired, in static and tilting variants), shaft melting gas furnaces (SMG, up to 7 tons/hour capacity), holding furnaces (STE radiant and STI immersion-heated, up to 22.5-ton capacity), and supporting accessories such as transport ladles and ladle heaters. Core process IP centers on proprietary dosing unit technology (±1% dosing precision, vacuum and pressurized configurations, 30 kg in 5 seconds), the Pro-Dose closed-system metal transfer system (up to 10 kg/s, 160 kg dosing weights), and immersion heating elements (claimed up to 80% energy cost reduction and 95% reduction in metal oxidation versus conventional methods).

STØTEK monetizes through one-time capital equipment sales of customized furnace systems, supplemented by an installed-base annuity from OEM spare parts (warehoused in Europe, North America, and Asia), service inspections, refractory lining, staff training, and 24/7 service level agreements. Distribution is hybrid: wholly-owned subsidiaries in Denmark (HQ), the United States (Støtek Inc., Pewaukee, Wisconsin, est. 2004), and China (Støtek China, Taicang, Suzhou, production since 2022) carry direct enterprise field sales, while independent agents cover Spain, Portugal, Czech Republic, Slovakia, Korea, Taiwan, India, Brazil, Turkey, Mexico, Italy, and Hungary. Marketing is content-driven (technical blogs, customer case studies with Audi and Volkswagen, downloadable datasheets) supported by LinkedIn, Facebook, and YouTube channels. The company holds ISO 9001 and ISO 14001 certifications.

The customer base is concentrated in automotive OEMs and Tier 1/2 sub-suppliers and includes Volkswagen (a documented relationship since 2009 with the Kassel plant saving €10,000 per furnace per year on energy), Audi, BMW, Mercedes-Benz, Ford, Chrysler, Honda, Volvo, Skoda, and EV manufacturer NIO. The company employs approximately 65 people and is majority-owned by CEO Hans Henrik Würtz, who took over the business in 2007 and sold a minority stake to Danish industrial investor Industri Udvikling in 2024 following an earlier 2019 investment from Dansk Ejerkapital.

Direct peers

• StrikoWestofen: German-headquartered manufacturer of aluminum melting and dosing furnaces, including dosing and holding furnace technology for die-casting foundries. StrikoWestofen is STØTEK's closest direct competitor in the automotive aluminum furnace niche, with overlapping product lines and shared OEM customers.
• OTTO JUNKER: German manufacturer of industrial melting and holding furnaces for aluminum, copper, and zinc, with a strong presence in automotive and specialty alloy foundries. Overlaps with STØTEK in aluminum holding and dosing technology for die-casting.
• Hertwich Engineering (Danieli Group): Austrian manufacturer of aluminum remelting, dosing, and casting equipment, now part of the Danieli group. Hertwich sells aluminum dosing and holding furnaces directly comparable to STØTEK's product line, with strong presence in extrusion and casting plants.

Broad incumbents

• Inductotherm Group: Large, diversified US-based manufacturer of induction melting and holding equipment for metals. Inductotherm competes with STØTEK in aluminum holding and melting, particularly for larger foundry installations, and is much larger and broader in scope.
• ABP Induction Systems: Germany-based global supplier of induction furnace systems for melting, holding, and dosing of ferrous and non-ferrous metals. ABP competes in the same automotive aluminum furnace space as STØTEK, but with a broader product portfolio and larger scale.
• Seco/Warwick: Global supplier of industrial heat-processing furnaces for metals, including aluminum heat treatment and melting equipment. Seco/Warwick serves automotive and aerospace OEMs with a broader thermal-processing portfolio than STØTEK, partially overlapping in aluminum holding.

Emerging players

• Morgan Molten Metal Systems: Supplier of molten metal systems and consumables for aluminum and other non-ferrous foundries, including flow control and dosing components. Overlaps with STØTEK in dosing technology, but focuses on engineered flow components rather than complete furnace systems.
• Künzel (KUNKEL): European specialist in aluminum melting and holding furnaces serving foundries and die-casters. Smaller regional competitor that overlaps with STØTEK in dosing and holding furnace technology for European automotive customers.

Others

• Foseco (Vesuvius plc): Global supplier of consumables, refractories, and engineered solutions for foundries, including die-casting customers. Foseco is not a direct furnace competitor but is a complementary supplier into the same automotive foundry customers as STØTEK.
• Pyrotek: Global supplier of engineered equipment, consumables, and services for the aluminum industry, including molten metal handling and dosing components. Pyrotek serves the same aluminum foundry customers as STØTEK with adjacent metal handling technology.
