What Technisch Bureau Nusselder does

Technisch Bureau Nusselder, operating commercially as Tebunus Tube Bending B.V., is a privately held Dutch specialty manufacturer founded in 1984 and headquartered in Ursem, North Holland. The company provides precision cold tube bending services using a fleet of eight CNC-controlled Schwarze Robitec mandrel bending machines capable of forming tubes from Ø2.5mm to Ø114.3mm in steel and stainless steel, up to Ø168.3mm in aluminum, and up to 22 meters in length. Its service portfolio spans standard bending, specialized hairpin (U-tube) production for heat exchangers and condensers, hydraulic pipe assemblies, and custom tool fabrication through an in-house tooling workshop (Eigen Gereedschapsmakerij). Quality is measured at 0.12–0.19% rejection rates and certified under ISO 9001, with hairpin work additionally conforming to VGB standards.

Tebunus serves a diversified B2B industrial customer base across petrochemical and chemical (heat exchangers, condensers, boiler components), shipbuilding and yacht building (Feadship-linked De Vries Scheepsbouw), machine building, industrial construction, and design/architecture. Named enterprise customers include ENGIE, Stork, Petrogas, NedTrain, Kverneland Group, Lekkerkerker Dairy & Food Equipment, and Mannen van Staal. Go-to-market is direct B2B sales with quote-based, project-specific pricing, multi-year contracts, and same-day inquiry response; the multi-language website (Dutch, English, French, German) and a dedicated export sales channel indicate active international outreach alongside the Dutch domestic base. Distribution is direct-only with no resellers.

In October 2024 the company divested its tube trading business (Tebunus Tube Trading) following the retirement of Peter de Vries, refocusing exclusively on tube bending. Recent strategic moves include a 2025 closed-loop recycling partnership with Van Est Metals, ongoing capability expansion in high-spec petrochemical alloys (Alloy 800HT refinery work), and incremental movement from pure bending service toward finished subassemblies such as hydraulic pipe kits. Ownership appears concentrated within the founding/management team under Director Mieke Genefaas, with no disclosed external institutional investment.
