CUSTOM MAGNETIC DESIGN & ENGINEERING
We combine our knowledge and experience with new innovations and technology to give you the best magnet and custom magnetic assembly design and engineering assistance available.
During the design phase of your project, it is important to consider the complexities associated with using magnetic materials. Both the magnetic performance and how the magnet will be integrated into the final solution are important.
Magnetic materials, unlike common commercial materials that have ASTM classifications, are difficult to manufacture and fabricate; they present a special set of challenges. Therefore, it is necessary for the design team to take special care when creating a custom solution for your application.
SDM designs engineered-to-order magnetic assemblies and magnet solutions for a wide range of applications, such as medical devices, senor triggering, electromechanical devices, and more.
Oxidizing or reactive environments
Magnetic materials are typically environmentally unstable. They can be highly reactive and prone to oxidation. Common coating and plating solutions usually do not translate to magnetic alloy.
Magnetic materials gain or lose magnetic field relative to the operational temperature fluctuations. The design must take into account magnetic performance through a temperature spectrum.
These materials can experience irreparable harm at extreme temperature exposures. This harm is irrecoverable and represents an effective partial or total demagnetization of the magnet.
Difficulty machining magnetic material
Because conventional machine tools and machining methods are not feasible, magnets can be challenging to fabricate.
Non-linear magnetic force
They can also be challenging to design, since the magnetic field density and resulting force are not linear relative to distance.
Integration and retention
Common methods of component integration and retention such as tapped holes, shoulders, through holes, staking, and tapers are expensive to employ. The integration of a magnet into a sub-assembly requires a functional knowledge base when designing an integration scheme.
Magnetic materials are magnetized. This seems obvious, but magnetized magnets and sub-assemblies present a unique set handling and integration problems. Issues can range from protecting the operators to demagnetizing of the magnet itself. This aspect must be accounted for early in the design phase.
Unlike common materials
Commonly requested specifications attributed to conventional materials—such as aluminum, steel alloys, and plastic—are usually challenging to implement with magnets and magnetic materials. These specifications, usually indicated on a drawing by default, may add cost and complexity when manufacturing a magnet or magnetic assembly. It is important to review the relevance of these industry standard features and specifications when designing and specifying a magnet or magnetic assembly.
Optimization for Performance, Cost, & Price Volatility.
Magnet alloy is often the most expensive part of an assembly. By optimizing a magnet design for an application using simulation software, Dura Magnetics can significantly reduce the cost.
