Raboutet

What Raboutet does

Raboutet is a French privately-held micro-mechanical manufacturing company founded in 1983 in Cluses, Haute-Savoie, focused exclusively on the machining and finishing of pure molybdenum and pure tantalum. Its production stack spans four integrated capabilities delivered from a single facility: CNC conventional machining (turning, milling, drilling, tapping, rolling, bending), molybdenum-specific chemical cleaning, vacuum heat treatment using a BMI furnace (600mm³ capacity, 10-6 mbar secondary vacuum, up to 1200°C), and packaging inside a Class 10,000 clean room certified every two years by a specialized third party. The firm sells two ways: custom manufacturing of complex finished parts from customer drawings, and direct sale of standardized fasteners held in stock in multiple finish states (cleaned, chemically treated, degassed, and nitrogen-vacuum-packed).

The company's customer base addresses high-vacuum and ultravacuum end uses — semiconductor manufacturing, molecular beam epitaxy (MBE), epitaxy, microelectronics, electronic and power tubes, vacuum furnace construction, and physics-research laboratories — where contamination control and outgassing performance are decisive. Raboutet goes to market through its own multilingual website (French, English, Spanish, Chinese), phone and email, and presence at vacuum and semiconductor trade events, with all quotes issued on a direct-contact basis and pricing not publicly disclosed. There is no public listing, no parent company, no institutional investor, no M&A history, no disclosed funding, and only 1–10 employees reported, consistent with a founder-operated specialist precision shop rather than a scaled industrial platform.

Core offering

Raboutet is a French micro-mechanics manufacturer that machines pure molybdenum and pure tantalum into finished industrial components for the vacuum and ultravacuum industry. Since 1983, the company has provided custom CNC machining of refractory metals from customer drawings, dedicated chemical cleaning for molybdenum, vacuum heat treatment via a large-capacity BMI furnace, and a stock of standardized fasteners in cleaned, treated, or fully degassed and vacuum-packed conditions.

Product overview

Raboutet is a micro-mechanics company specializing in strategic materials (molybdenum and tantalum) for the vacuum and ultravacuum industry since 1983. The company offers an integrated portfolio of four core services: (1) Conventional Machining using CNC equipment for complex industrial parts, (2) Chemical Treatments with molybdenum-exclusive cleaning installations, (3) Heat Treatments using a large-capacity vacuum furnace for complete decontamination, and (4) a Stock of standardized fasteners in pure molybdenum and tantalale (cleaned, treated, or vacuum-packed). All services are designed to meet the stringent cleanliness requirements of semiconductor, MBE, epitaxy, and electronic tube industries.

Functional benefit

Products and services

• Conventional Machining (Usinage conventionnel) CNC machining service for molybdenum and tantalum industrial parts, including turning, milling, drilling, tapping, rolling, and bending operations. Delivers finished, complex parts from customer plans for vacuum and ultravacuum applications.
• Chemical Treatments (Traitements chimiques) Dedicated chemical cleaning and decontamination service for molybdenum parts, performed in-house using an installation exclusively dedicated to molybdenum, followed by nitrogen vacuum packing and clean room storage.
• Heat Treatments (Traitements thermiques) Vacuum heat treatment using a large-capacity BMI furnace (600mm³, 10⁻⁶ mbar secondary vacuum, up to 1200°C) to fully degas and decontaminate chemically treated molybdenum parts, achieving 100% cleanliness.
• Fastener Stock (Visserie) Stock of standardized fasteners in pure molybdenum and pure tantalum, available in three conditions: cleaned; cleaned and chemically treated; or cleaned, chemically treated, degassed, and nitrogen vacuum packed, with double-chamber packaging options.

Quantifiable outcome

• Parts achieve 100% cleanliness and remain clean until customer unpacking in their own clean room

Broad incumbents

• Lesker Company (Kurt J. Lesker): Lesker is a global supplier of vacuum components, materials, and thin-film deposition hardware used across semiconductor and research end-markets. Comparable to Raboutet in serving MBE, epitaxy, and vacuum-furnace customers, but with a catalog business model rather than custom micro-machining.
• Mersen: Mersen is a French-listed specialty materials group with significant refractory metals and high-purity materials capabilities, including molybdenum and tantalum products for semiconductor and electronics customers. Comparable to Raboutet in serving the same vacuum/ultra-pure materials space, but at vastly larger scale and across a broader product portfolio.
• Plansee Group: Plansee is one of the world's largest processors of molybdenum, tungsten, tantalum, and other refractory metals, producing semi-finished parts, components, and fasteners for electronics, semiconductor, and vacuum applications. Comparable to Raboutet in serving vacuum-grade refractory metal parts but operates as a global industrial incumbent, not a micro-shop.
• H.C. Starck (Mersen Tungsten & Specialty Refractory Operations): H.C. Starck is a long-established processor of refractory metals including molybdenum and tantalum, serving electronics, semiconductor, and vacuum industries. Comparable to Raboutet in material focus and end-markets, but at much larger industrial scale with vertically integrated raw materials.

Emerging players

• MDC Vacuum Products (MDC Precision): MDC supplies standard vacuum components, fittings, and custom-fabricated chambers and hardware to semiconductor and research customers. Comparable to Raboutet in supplying consumables and custom hardware into the same vacuum customer base, though broader in material scope.

Others

• Pfeiffer Vacuum: Pfeiffer Vacuum is a leading European manufacturer of vacuum pumps, leak detectors, and related instrumentation, headquartered in Germany. Comparable as a downstream customer-side player in the same vacuum ecosystem that Raboutet supplies, though operating in equipment rather than components.
• VAT Group: VAT Group is a Swiss-based global leader in vacuum valves and motion components for semiconductor manufacturing and high-vacuum applications. Comparable to Raboutet as part of the same vacuum-industry supply chain serving semiconductor and research customers, though focused on valves rather than refractory metal parts.

Direct peers

• VACUUM FABRICATORS & ENGINEERS: Custom vacuum chamber fabrication shop producing stainless steel and specialty metal vacuum vessels, bellows, and components for semiconductor and research customers. Comparable to Raboutet as a specialty fabricator serving vacuum-system builders, though primarily stainless rather than refractory metals.
