What TechnoPlus Industries does

TechnoPlus Industries is a French industrial SME founded in 1986 in Les Pennes-Mirabeau (Bouches-du-Rhône) that designs and manufactures high-precision mechanical components for the nuclear, defense, aeronautics, and space sectors. Its core competencies span five integrated service lines: conception and engineering (SolidWorks, CATIA, AutoCAD), 5-axis CNC precision machining in 4,000 m² of air-conditioned workshops (Mazak Integrex 300/500, DOOSAN Puma, AGIE wire EDM), TIG and electron beam welding (including 15 kW Techmeta EB and Nicrobraz induction brazing via subsidiary SDMS), large-scale assembly and integration in 1,200 m² of clean halls with 5–20T bridge cranes and underwater testing pits at the Saint-Paul-lez-Durance site, and on-site nuclear maintenance and intervention services backed by CEFRI E certification. The company also markets a complementary consumable — Lubrifiant 2 PMUC, an EDF-approved graphite dry lubricant for nuclear plant use.

The business operates as a B2B project-based industrial services provider, selling custom-engineered components and assemblies on a quote basis to a concentrated roster of French state-tied prime contractors and OEMs — including Naval Group, TechnicAtome, Thales, Airbus, EDF, Framatome, ITER, Orano, CNIM, IRSN, ECA, LISI Aerospace, APCO, and Thales Alenia Space. Pricing is per-project, tied to specifications, materials, and regulatory requirements; contracts frequently run multi-year under nuclear and defense code regimes (RCC-M, RCC-MX, RCC-MRx). Certifications (ISO 19443:2018, EN 9100, ISO 9001, CEFRI E, PART 21G) and 40 years of accumulated nuclear-propulsion know-how function as the primary barriers to entry.

Ownership is held by TechnicAtome (70%) and Onet Technologies (30%) following a 2024 restructuring that ended the company's prior independence under the Impala Group with CNIM. Geographic footprint remains domestic French (two production sites near Aix-en-Provence and CEA Cadarache), with distribution entirely direct to enterprise customers; no public revenue figure is disclosed.

Core offering

TechnoPlus Industries is an industrial SME that designs and manufactures critical precision mechanical components for the nuclear, defence, aeronautics and space sectors. The company offers five core services covering the full project lifecycle — custom design and engineering, 5-axis CNC precision machining, TIG and electron beam welding, large-scale assembly/testing/integration, and on-site nuclear maintenance — supported by 4,000 m² of machining workshops and 1,200 m² of clean assembly halls. It also sells Lubrifiant 2 PMUC, a PMUC-approved graphite dry lubricant for nuclear power plants.

Product overview

TechnoPlus Industries is an industrial SME offering a comprehensive suite of precision manufacturing services organized around five core competencies: Conception & Réalisation (custom mechanical engineering and design), Usinage de Précision (CNC precision machining), Soudage & Brasage (TIG and electron beam welding), Montage, Essai & Intégration (assembly, testing, and integration), and Maintenance & Intervention Nucléaire (nuclear maintenance services). The company also sells a complementary product, Lubrifiant 2 PMUC, a dry graphite-based lubricant approved for nuclear plant use. Services span the full project lifecycle from design studies through machining, inspection, testing, assembly, and on-site integration. The portfolio is unified by the company's focus on high-precision mechanical components for critical applications in nuclear, defense, aeronautics, and space industries.
