Speed, Dedication, Motivation.

Since 2004, SDM Magnetics has focused on permanent magnets and magnetic assemblies for industrial and commercial applications. Over time, our work has expanded from supplying custom magnets to supporting projects involving material selection, magnetic simulation, prototyping, assembly, and production.

Our capabilities cover Neodymium magnets, Samarium Cobalt magnets, bonded magnets, AlNiCo magnets, and related magnetic assemblies. Projects may begin with drawings, existing samples, defined magnetic performance targets, or early application requirements. The scope of support depends on the material, component design, production process, and validation needs.

From Permanent Magnets to Magnetic Assemblies

Custom permanent magnets remain an important part of our work, but many projects involve more than material grade, shape, and dimensions. Magnetic performance is also influenced by how magnets are positioned, combined with other components, and used within the final product.

As project requirements became more complex, SDM expanded its capabilities from custom magnet manufacturing to magnetic assemblies and related engineering support. Some customers require individual magnets made to drawing, while others need complete magnetic assemblies developed around specific magnetic, mechanical, and production requirements.

Materials and Manufacturing Capabilities

SDM works with Neodymium (NdFeB) magnets, Samarium Cobalt (SmCo) magnets, ferrite magnets, AlNiCo magnets, and bonded magnets. These materials differ in magnetic output, temperature capability, corrosion resistance, mechanical properties, and manufacturing route, so material selection is reviewed together with the actual working conditions and production requirements.

For individual magnets, our manufacturing capabilities cover standard and custom shapes, magnetization patterns, surface treatments, dimensional control, and magnetic performance verification. The production route is defined according to the material, product requirements, tooling, and inspection needs.

For magnetic assemblies, the work extends to integrating magnets with other components and managing the corresponding production and inspection requirements. Component requirements, magnetic performance, production methods, and final inspection are considered together to support consistent and repeatable production.

Engineering and Project Support

Engineering support helps connect magnetic requirements with a manufacturable product. Depending on the project, this may involve material evaluation, magnetic simulation, prototype development, and sample verification.

Possible solutions can be compared before the material, dimensions, magnetic performance, and assembly approach are finalized. This helps translate application requirements into specifications that can be evaluated through samples and inspection, then reproduced during later production.

Quality, Compliance, and Supply Support

Quality requirements vary according to the magnet or assembly, its intended use, and the specifications agreed for the project. Inspection and documentation are therefore defined according to material properties, dimensions, magnetic performance, surface treatment, assembly quality, and other project requirements.

SDM Magnetics operates under quality and environmental management systems certified to ISO 9001, IATF 16949, and ISO 14001. Depending on the project, inspection and documentation may include dimensional inspection, magnetic testing, material declarations, traceability records, and third-party test reports for applicable RoHS, REACH, or other project-specific compliance requirements.

For rare earth magnet projects, raw material availability and market fluctuations can also affect quotation, lead time, and production planning. SDM maintains sourcing relationships with established material suppliers and follows relevant market changes when coordinating material sourcing and production schedules.

Customer Experience Across Industries

SDM Magnetics has supported customers and supply chain partners in automotive, industrial automation, consumer electronics, household appliances, energy, and other technical fields. Although project requirements vary across industries, product consistency, magnetic performance, traceability, compliance documentation, and delivery remain common concerns.
