What SK Technology does

SK TECHNOLOGY GmbH is a privately held German precision-engineering manufacturer operating 297 employees across two integrated plants — a 10,000 m² headquarters in Roding focused on prototypes, zero and small series, and a 5,000 m² plant in Waldmünchen dedicated to medium-batch serial production of milled and turned parts. The company operates approximately 125 high-end CNC machines across 36 milling centers (including six 5-axis machining centers with robot systems), 29 CNC lathes, CNC grinding (surface, cylindrical, profile, lapping, honing), EDM wire and die-sink erosion, and an ISO Class 7 cleanroom with integrated darkroom; measurement is anchored by Europe's most advanced ZEISS XENOS 3D coordinate measuring machine with 0.3 µm + L/1,000 accuracy. All operations are EN 9100:2018-certified for aerospace, supplemented by ISO 9001 and Penetrant Testing Level 2 (PT2) certifications, and the company runs an integrated SK TECHNOLOGY 4.0 digital production stack connecting ERP, MES, CAM, QA, and tool management.

SK Technology functions as a contract manufacturer and strategic development partner, engaging early in customer design cycles to advise on part optimization, material selection (including difficult-to-machine alloys such as titanium, Inconel, mu-metal, molybdenum), and supply chain organization, with project management as the primary commercial interface. Revenue is generated transaction-by-transaction on a quote-based pricing model tied to part complexity, tolerance, material, and volume, spanning prototypes through medium batches. The company's vertical segmentation spans aerospace, defense and security; automotive and motorsport; semiconductor and vacuum technology; medical technology; optical industry; and plant and special machine construction, with named enterprise customers including Airbus, BMW, Audi Sport, Continental, Infineon, Siemens, Bosch, Hermle, OHB, Ariane Group, and Marelli.

The business is family-owned under the Kulzer family within the SK Group parent, with Stefan Kulzer serving as Executive Partner and his son Benedikt Kulzer as Managing Director following a November 2019 succession; no external institutional or private-equity capital is evidenced in available sources. The company rebranded from Stangl & Co. GmbH Präzisionstechnik to SK TECHNOLOGY GmbH in May 2022 and has accumulated a multi-decade award track record including Bayerns Best 50 (2016), SME Grand Prix (2014), Bavarian SME Prize (2024), and Great Place to Work certification (2023). Geographic footprint is concentrated in Europe, and revenue figures are not publicly disclosed.
