Stueken

What Stueken does

Stueken (legal name Hubert Stücken GmbH & Co. KG) is a German family-owned precision metal parts manufacturer founded in 1931 and headquartered in Rinteln, Germany. The company operates five wholly-owned production sites in Germany, the Czech Republic, the United States (Fountain Inn, South Carolina), China (Shanghai), and India (Pune), employing more than 1,200 people across three continents. Itself-described as the world market leader for deep-drawn components, Stueken specializes in small, high-precision metal parts and assemblies with tight tolerances and millionfold repeatability, produced at billion-part annual volumes for automotive, electromobility, electronics, industrial, medical technology, household appliance, and building technology OEMs.

The company's core technology is deep drawing, complemented by stamping and forming, assembly, plastic injection molding (for hybrid metal-plastic parts), in-house tool design and tool shops, and an unusually broad in-house finishing range that includes the proprietary SWEP15® surface hardening process, heat treatment, electroplating, electropolishing, cryo-treatment, machining, welding, and Class 7 cleanroom production. Engineering services span prototyping, FEM-based product development simulation, and customer-specific testing. Quality and regulatory credentials include ISO 13485 (medical devices, at North America and Czech Republic), ISO 14001, and ISO 50001 certifications, supporting a dedicated STÜKEN MEDICAL division for healthcare applications.

Stueken generates revenue primarily through hardware sales of precision parts and assemblies to enterprise industrial customers under a quote-based, customer-specific pricing model, with supplementary engineering and development services. It sells directly through enterprise field sales and acts as both a development partner and serial producer for demanding OEM programs. Capital allocation in recent years has skewed toward vertical integration and capacity expansion, including a 28 million euro in-house electroplating facility in Rinteln, a new plant in India, and Shanghai capacity doubling.
