What Wolfensberger AG does

Wolfensberger AG is a privately held Swiss precision casting and CNC machining manufacturer founded in 1924 and headquartered in Bauma, Switzerland, where it operates two co-located plants: a foundry (Werk 1, Bäretswilerstrasse 45) and a machining technology facility (Werk 2, Bliggenswilerstrasse 5). The company employs approximately 145-150 people and serves demanding industrial customers in Switzerland and internationally across nine verticals — mechanical and plant engineering, construction machinery, automotive, power engineering, military, railway, marine, food, and mining.

Its core offering is built around proprietary wax-free investment casting under the Ceracore® brand (with Shelf and Hybrid variants) and the Exacast® precision casting process, complemented by traditional sand casting from lot size 10, pre-cast CNC blanks, multi-axis CNC turning and milling (3-axis vertical, 4-/5-axis horizontal centres on Heidenhain, Siemens, and Fanuc controls), in-house toolmaking, and full assembly services delivered as a general contractor. The company works across more than 100 alloys including spheroidal graphite cast iron (GJS/Sphäroguss), cast steel, nickel alloys, Ni-Resist, and wear cast iron, and claims the Ceracore process can reduce product launch time by up to 50%.

Wolfensberger generates revenue through direct, quote-based B2B sales to enterprise customers worldwide — supported by an inquiry form with CAD file upload on its multilingual (German/English) website, an online appointment booking tool, and a sales team headed by a Verkaufsleiter. Pricing is non-public and handled per inquiry; material surcharge schedules are published periodically (e.g. June and July 2026 dates referenced). The company holds a dense portfolio of certifications — ISO 9001:2015, IQNet, ABS, DNV (iron and steel castings), Korean Register, Lloyd's Register (iron and steel castings), Bureau Veritas, and a voluntary climate/energy efficiency commitment — that are central to qualifying for marine, railway, power, and military work. Leadership comprises CEO André Masuhr and CFO Thomas Baumann; the company has no disclosed external investors, no M&A activity, and celebrated its 100th anniversary in 2024.

Core offering

Wolfensberger AG is a Swiss precision casting and machining manufacturer producing high-quality, ready-to-install cast components from spheroidal graphite cast iron (GJS), cast steel, nickel alloys, Ni-Resist, and wear cast iron. The company operates two integrated plants in Bauma (foundry and CNC machining), uses proprietary Ceracore and Exacast investment casting processes alongside sand casting, and offers complete turnkey solutions including CNC turning/milling and assembly of complete subassemblies.

Product overview

Wolfensberger AG is a Swiss precision casting and machining company offering an integrated portfolio of manufacturing services. The core offering centers on investment casting using proprietary Ceracore® (Shelf, Hybrid) and Exacast® processes, complemented by traditional sand casting starting at lot size 10. The company provides complete in-house value chain including pre-cast blanks for CNC machining, state-of-the-art CNC turning and milling, and final assembly services. They work with diverse materials including spheroidal graphite cast iron (Sphäroguss/GJS), cast steel, nickel alloys, Ni-Resist, and wear cast iron. Stahlguss 2.0 processes reportedly reduce product launch time by up to 50%.

Others

• Norican Group (DISA / Wheelabrator): Global foundry equipment and surface-treatment supplier rather than a casting competitor. Comparable as an adjacent industry participant: same end customers (foundries) but supplies casting equipment, sand systems, and surface finishing used by shops like Wolfensberger rather than competing for casting orders.
• ASK Chemicals GmbH: Specialty chemicals supplier for foundries (binders, coatings, additives used in investment and sand casting). Compares as an ecosystem supplier into Wolfensberger's process chain rather than a casting competitor — useful context on raw-material and process-chemical supply dynamics.

Direct peers

• Tekinvest S.p.A. / Italian foundry group: Network of Italian and southern-European investment and sand casting shops serving automotive, hydraulics, and machinery customers. Directly comparable as mid-sized European precision casting competitors in the same niche Wolfensberger occupies.
• Eisenwerk Würth GmbH: Mid-sized German steel and iron foundry (Eisenwerk) supplying wear-resistant and structural castings to mining, cement, and rail customers. Closely comparable in scale (~150-300 employees) and in the wear-/spheroidal-graphite iron portfolio that mirrors Wolfensberger's Werkstoffe range.
• Impro Industries (China): Asia-headquartered investment casting group producing precision and machined cast components for automotive, hydraulics, and industrial OEMs. Comparable on investment casting technology and on integrated CNC finishing, though at materially larger scale and lower Swiss/European cost base.
• Gontermann-Peipers GmbH: German steel foundry producing heavy wear- and heat-resistant castings for cement, mining, and steel-mill customers. Directly comparable on iron/steel casting materials and the same abrasive-environment mining customer segment Wolfensberger targets.

Broad incumbents

• Sulzer Ltd. Swiss industrial group with a long-standing foundry and casting capability serving pumps, rotating equipment, and energy customers. Comparable due to Swiss-anchored casting operations serving defense, marine, and energy — overlapping exactly with Wolfensberger's end-market verticals.
• Precision Castparts Corp. (PCC, Berkshire Hathaway): The world's largest investment casting group (now under Berkshire Hathaway). Directly comparable on investment casting technology and on serving aerospace, defense, and industrial OEMs — though PCC operates at vastly greater scale and an aerospace-weighted mix, making it a benchmark rather than a direct SME-level competitor.
• Voestalpine AG: Austrian steel and specialty alloy group with foundry and casting operations serving rail, automotive, and industrial tooling. Comparable for the overlap in steel castings and rail/automotive end markets, but voestalpine is a vertically integrated steel major rather than a job-shop foundry.
• Georg Fischer AG (+GF+): Swiss-headquartered industrial group historically centered on iron and steel casting for automotive, industrial, and water applications. Directly comparable as a Swiss precision casting incumbent, though GF operates at far larger scale (thousands of employees) and now also in plastics processing.
