Sintex

What Sintex does

Sintex A/S is a Danish precision powder metallurgy company headquartered in Hobro, Denmark, founded in 1997 by former Grundfos pioneers to commercialize sintered stainless steel components originally developed for Grundfos. The company operates as an independent joint stock company within the Grundfos Group and employs approximately 170 people. Its core manufacturing platform spans three complementary processes — conventional sintering, Metal Injection Molding (MIM), and Metal Powder Extrusion — all centered on stainless steel and soft magnetic materials. Building on this platform, Sintex sells a portfolio of engineered components including friction shims, shaft bearings, magnetic couplings (including High Hot Couplings rated to 590°C), Soft Magnetic Composites (SMC) for motors and transformers, permanent magnets (NdFeB, SmCo, ferrite, and the patented Cradle2Cradle-compliant IP Magnet), permanent magnet rotors, and sintered filter solutions. The company holds multiple registered patents and has qualified its SMC materials for space-industry applications (ESCC 3201/013, MIL-STD-981, MIL-PRF-27).

The company's business model is direct B2B custom component manufacturing: Sintex engages customers early in the design process and co-develops tailored stainless steel and magnetic components through to serial production. Sales are handled by a dedicated in-house team including a Sales Director, Senior Business Development Manager, Senior Sales Manager, and Area Sales Managers; pricing is quote-based and not publicly disclosed. Sintex serves eight vertical markets — Automotive, Motors & Pumps, Medico/Medical, Electronics/Audio, Energy, Food Industry, Defence, and Aerospace & Robotics — with named customers and partners including Grundfos, Volkswagen, DaimlerChrysler, Ford, Peugeot, Citroen, FLUX A/S (space), Danfysik (particle accelerators), Aalborg University, and Aarhus University. The company holds ISO 9001, ISO 14001, ISO 50001, ISO 45001, IATF 16949, and RoHS certifications, and operates from a single European production site with documented sustainability initiatives including green hydrogen supply, waste-heat recovery, and Power-to-X collaboration with Air Liquide.
