A Few Questions to Answer Before Customizing Magnets
Considerations when you customize magnets
When designing permanent magnets or magnetic assemblies for new applications, there are many factors to consider.
1. What is the main function of the magnet?
Permanent magnets are typically used for one of seven purposes: holding, moving, clamping, filtering, activating sensors, generating current, or creating a damping effect. Before designing a magnet, you must first understand exactly how to use it.
2. Will the magnet withstand physical force?
All magnetic materials are generally brittle. To prevent constant or sudden shock, the magnets can be coated or housed in a steel case.
3. Are magnets affected by extreme temperatures?
Magnets of different materials and grades have very different maximum operating temperatures and temperature coefficients. For example, standard-grade neodymium magnets suffer irreversible performance losses at 80 degrees Celsius, while alnico magnets can withstand temperatures as high as 500 degrees Celsius before suffering irreversible losses.
4. Will the magnet be used in a corrosive environment?
Some permanent magnets, such as neodymium magnets,are extremely susceptible to corrosion, while ferrite magnets never corrode.
5. Does the magnet require a specific magnetic field strength?
Magnetic field strength is a value that contributes to the overall magnetic performance of a magnet. Certain applications, such as sensor activation, require magnets with a specific field strength or open-circuit flux density (measured in Gauss).
6. Will the magnet work through the air gap?
Magnets do not always need to be in direct contact with the surface or component they interact with, and some magnetic materials will provide greater magnetic field strengths than others.
7. How will the magnet be held in place?
Although often simple in terms of solutions, the method of securing is a crucial consideration, whether it is punching or dispensing, or choosing a threaded steel shell assembly.
Design Your Custom Magnets
After considering the above questions, in order to turn your ideas into magnetic finished products, our production team needs sketches or technical drawings and is always willing to provide suggestions. In order to turn your idea into a magnetic finished product, wealso need the following information: Shape, dimensions (including tolerances),type and grade of magnetic material, type of coating, direction of magnetization, desired physical tension, and maximum operating temperature
