What Sindlhauser Materials does

Sindlhauser Materials GmbH is a privately held German specialty materials manufacturer founded in 1995 and headquartered in Kempten (Allgäu). The company designs, manufactures, and supplies materials and components for the vacuum coating industry, with a core product portfolio spanning sputter targets (oxide and non-oxide ceramics, metals, alloys, precious metals, and rare earth metals) in planar and tubular configurations and at purities up to 99.9999% (7N), LaB6 cathodes for plasma-supported coating processes, ceramic suspensions and slurries, granulates and evaporation raw materials, and tungsten/tantalum/molybdenum evaporation components (boats, crucibles, coils). Manufacturing relies on vacuum melting, sintering at temperatures exceeding 2000°C, hot pressing, and hot isostatic pressing (HIP), with reactive materials handled under inert conditions.

The company operates as a vertically integrated system supplier, bundling its materials with a services layer that includes target bonding (indium, SnAg, and Nanofoil processes for diameters up to 400mm and lengths up to 3000mm), ultrasonic quality inspection, CNC milling, full quality documentation and traceability, specialized packaging (cleanroom-compatible, vacuum shrink-wrapped, argon/nitrogen-filled), global express logistics, and recycling services for spent targets and vacuum pump oils. It is ISO 9001:2015 certified (TÜV) and REACH-compliant, with self-registration of eight substances and EU Conflict Minerals Regulation (2017/821) disclosure.

Sindlhauser serves industrial B2B customers in five primary verticals — semiconductor, sensor, optical, medical technology, and light — plus general industrial coating. Distribution is direct via enterprise field sales, supported by an international partner network and an active presence at trade shows (V2025, PSE 2024, Medtec 2024, OPTATEC 2024). Revenue is generated primarily through hardware sales of materials and targets, complemented by professional services (bonding, recycling, oil analysis, contract milling). A newer line, the patent-pending PeroLab nano-scaled LaB6 near-infrared absorber, extends the company into additive manufacturing, laser welding, and light filtration applications.

Core offering

Sindlhauser Materials GmbH designs, manufactures, and supplies sputtering targets and vacuum coating materials — including oxide and non-oxide ceramics, metals, alloys, rare earth metals, and precious metals — to industrial customers in the semiconductor, sensor, optics, and medical technology sectors. The company also provides integrated services such as target bonding, ultrasonic quality testing, CNC milling, specialized packaging, and recycling, enabling customers to source the full materials-to-target value chain from a single supplier.

Product overview

Sindlhauser Materials is a manufacturer and supplier of vacuum coating materials and related services, operating since 1995 from Kempten, Germany. The product portfolio centers on sputter targets — planar and tubular, monolithic or bonded — produced from a comprehensive range of materials including standard metals, precious metals, alloys, rare earth metals, oxide ceramics, non-oxide ceramics, and special materials (germanium, silicon, boron, carbon). Supporting products include LaB6 cathodes for plasma-assisted coating, ceramic suspensions/slurries for barrier layers, granulates and pellets for thermal evaporation, and evaporation components (boats, crucibles, coils) in tungsten, tantalum, and molybdenum. The company also supplies specialty vacuum pump oils and greases. The services layer — bond service, ultrasonic testing, CNC milling, quality documentation, specialist packaging, and recycling — is tightly integrated with the product business, enabling customers to source materials, have them bonded and quality-checked, and returned for recycling from a single supplier. A newer product line is PeroLab, a nano-scaled lanthanum hexaboride near-infrared absorber for additive manufacturing, laser welding, and optical filtration. Sindlhauser Materials operates as a system supplier combining materials expertise, manufacturing, and services.
