Custom Magnet and Magnetic Assembly Manufacturing

Custom MagnetsSince 1961, Dura has offered in-house manufacturing capabilities to take your prints and specifications for an engineered to order magnetic assembly or custom magnet from the drawing board to the production floor. From quick turn prototypes to large volume production runs, we have the equipment, technical expertise, strategic relationships with key vendors, and trained personnel to needed to manufacture custom magnets and magnetic assemblies to meet your specific application.

Unlike many of our peers who have eliminated their manufacturing capability and rely on distribution type sales to reduce overhead, we understand the customer’s need to present a finished print and specification to a vendor with a capacity to deliver highly engineered magnetic solutions.

When researching new potential vendors to manufacture your custom magnet or magnetic assembly, it is important to remember that typical details, appropriate for common commercial materials, such as aluminum, steel alloy, brass, etc., are usually challenging to implement with  magnets and magnetic materials and that these specifications indicated on a drawing, are often ignored by most magnet distributors.

Custom AssemblyThe operational performance of a magnet material can be very challenging to predict.  The magnet material used for your custom application may experience one or more of the following challenges:

  • Environmentally unstable (Highly reactive and prone to oxidation)
  • Gain or lose magnetic field relative to the operational temperature fluctuations
  • Can experience irreparable harm at extreme temperature exposures
  • Challenging to fabricate because conventional machine tools and machining methods are not feasible.
  • Challenging to design because the magnetic field density and force are not linear relative to distance.
  • Magnetic fields can create hazards for personal and some electronic equipment.
  • Magnet alloy is difficult to machine, so common methods of retainment such as tapped holes, shoulders, through holes, and tapers are expensive to employ.

If your potential vendor is not alerting you to these common manufacturing challenges during the quotation phase, you may be entering into a partnership with an order taker rather than finding a vendor capable of serving as your advocate, protecting your project from the common pit-falls experienced with magnetics manufacture.  Dura Magnetics will provide a quote as per your drawing, observing the indicated details and specifications, and/or open a dialog, questioning the potential issues.
