Sintermat is an innovative French industrial materials manufacturer founded in 2016 by Dr. Foad Naimi as a technology spin-off from powder metallurgy research at the University of Burgundy and SATT Sayens. Headquartered in Venarey-les-Laumes within the historical metallurgical hub of Côte-d’Or (Métal’Valley), the company is financially backed by Definvest (French Ministry of the Armed Forces managed by Bpifrance) and Sayens.

Sintermat specializes in industrializing Spark Plasma Sintering (SPS), also known as flash sintering. The company operates a park of 8 specialized industrial sintering machines, including a high-capacity hybrid SPS machine, representing one of the largest merchant flash-sintering production capabilities in Europe.

The company develops and manufactures “augmented materials” with ultrafine, nanostructured grain sizes and near 100% density without grain growth. Sintermat is ISO 9001 certified and has supplied advanced components to demanding industrial clients such as Safran for aeronautical turbine components, as well as partners in defense, luxury watchmaking, and industrial tooling.

Offer

Sintermat offers complete industrialization services from materials engineering, feasibility studies, and rapid prototyping through to series manufacturing of net-shape and near-net-shape parts via Spark Plasma Sintering.

SPS / Flash Sintering Technology: Simultaneous application of uniaxial mechanical pressure (up to 200 MPa) and high-intensity pulsed direct electric currents, reaching temperatures up to 2,400°C with heating ramps up to 1,000°C/minute. Achieves full densification 10 to 100 times faster than conventional sintering.
Material Capabilities: Refractory metals, technical ceramics (alumina, zirconia, carbides), intermetallic alloys, metal-matrix composites (MMCs), multi-material gradient structures, and valorized bio-sourced/natural recycled powders (leather scraps, plant residues, oyster shells).
Net-Shape Manufacturing: Direct consolidation into net-shape and near-net-shape geometries, significantly reducing raw material scrap and subsequent machining requirements.
Intellectual Property & R&D: Portfolio of over 10 proprietary patents covering SPS tooling, process parameters, and recycled/bio-sourced material formulations.
Applications: High-wear industrial tooling, ballistic armor and defense components, aerospace turbine wheels and heat-shield elements, and decorative luxury watch and jewelry cases.
