KUK-Wijdeven

What KUK-Wijdeven does

KUK-Wijdeven is a contract manufacturer specializing in customer-specific coils, transformers, and electromagnetic components. The entity is the Dutch (Oirschot) arm of KUK Group / KUK Electronic AG, a Swiss-rooted group founded in 1990 in Appenzell. The Wijdeven legal entity is reported at 11–50 employees, while the broader KUK Group operates approximately 1,000 people across 7 global production sites. The core technology centers on coil winding with ultra-fine wire from 0.010 mm, including air-core, bobbin, toroidal, and magnetic-core micro coils, complemented by high-frequency and low-frequency transformers. Manufacturing is supported by in-house-built machinery that accounts for roughly 90% of production capacity, enabling output of more than 200 million wound coils and more than 1 million mounted modules per year at the group level.

The product portfolio is organized into four solution areas: winding goods (air core coils, bobbin coils, transformers), complete module assembly (electric motors, overmoulding, potting), and PCB assembly on SMD and THT lines. These offerings target four primary verticals — automotive (stepper motors and solenoid valve units), industry (drive technology, building automation), medical & sensor (micro coils for devices such as the Hamilton Bonaduz MagPip liquid-handling robot), and defence (components for UAVs, radar, and communication protection). Compliance with RoHS and REACH is referenced.

The business model is B2B contract manufacturing with direct, sales-led engagement: customers initiate projects through website enquiries, and pricing is quote-based against customer-specific dimensions and series sizes, typically structured as multi-year supply contracts. GTM is supported by a multi-language website (DE, FR, IT, NL, SK, SV, ZH-CN), industry-specific sector pages, and trade-show participation such as electronica Shanghai 2026. The company is privately held, with no disclosed funding rounds, acquisitions, leadership changes, or subsidiaries in the source material.
