Sura Magnets

What Sura Magnets does

Sura Magnets AB is a Swedish specialty magnet manufacturer founded in 1954 in Surahammar and relocated in 1996 to its current headquarters at Ringvägen 40 C, Söderköping, Sweden. The company is privately held and operates as a single-site producer specializing in injection-molded and plastic-bonded permanent magnets, a niche in which it positions itself as the largest manufacturer in Scandinavia. It sells custom-designed magnetic components and assemblies to enterprise customers across three primary verticals: automotive (Hall sensor applications, steering and angle sensors, chip collector magnets), medical/medtech (hearing aids, life support and dialyze machines, PTFE-coated stirrer bars), and general industry (PM motors, sensors, separators, microphones, loudspeakers).

The core technology stack centers on injection molding and compression molding of plastic-bonded magnets combining rare-earth (NdFeB, SmCo, SmFeN) and ferrite powders with polymer binders such as PA6, PA12, and PPS. Sura Magnets produces both isotropic and anisotropic magnet configurations and supports multi-component/2-component molding plus insert molding for integrating externally produced parts. Material coverage also extends to sintered and cast rare-earth, AlNiCo, hard ferrite, and flexible magnet formats. Magnet designs are simulated and verified using 2D and 3D Finite Element Analysis (FEA), complex multi-pole magnetic patterns are generated via custom in-house designed magnetizing fixtures, and flux values are calibrated to 0.5–1.0% tolerance using a Magnet-Setter with stabilization to remove initial flux loss. In-house tool design and manufacturing for injection molds shortens lead times on tooling maintenance, repair, and new programs. The company holds IATF 16949 (automotive quality management) and ISO 14001 (environmental management) certifications and runs fully automated molding machines 24/7 alongside manual machines for lower-volume products.

Commercially, Sura Magnets sells through a direct enterprise field-sales model with a sales organization that includes the CEO & Purchasing/Sales Manager, a KAM for Automotive, Inside Sales/Customer Support, and dedicated department contacts for Orders, Quality, and Economy. Pricing is custom quote-based, determined by material, geometry, tolerance, magnetization complexity, and volume, with multi-year contracts typical for automotive and medical programs. Service revenue and customer engagement span FEA-based magnetic calculation, prototyping and pilot studies, magnetization fixture design, calibration/stabilization, custom tooling, and customer training in magnet technology delivered at the Söderköping plant or on customer sites. The product/marketing website supports downloadable catalogues in Swedish, English, and German, and the company plans future manufacturing expansion to additional locations beyond Söderköping.

Products and services

• Injection Molded Magnets Magnets manufactured using injection molding technology, combining magnetic powder (NdFeB, SmCo, SmFeN, Ferrite) with polymer binders (PA6, PA12, PPS) to produce complex shapes with tight tolerances and customized magnetic patterns as isotropic or anisotropic components.
• Multi-component Magnets Combination of injection molded magnets with polymer material molded in 2-component tooling, including insert molding where externally produced parts are robotically inserted into the mold tool.
• Sintered & Cast Magnets Magnets produced through powder metallurgy process including sintering and casting methods. Includes anisotropic sintered rare earth magnets (NdFeB, SmCo), the strongest magnets available, as well as rare earth free alternatives (Ferrite, AlNiCo).
