3. Neodymium magnets
Neodymium magnets are the most widely used type of rare-earth magnet in product design due to their high magnetic strength.
There are 3 common production techniques for neodymium magnets: sintering, bonding, and hot pressing.
- Sintered magnets are made by heating a mixture of neodymium, iron, and boron powders to create a solid piece.
- On the other hand, bonded neodymium magnets are made by mixing the magnetic powder with a binder, then molding it into the desired shape.
- Hot-pressed magnets are made by melting the magnetic powder and pressing it into the desired shape.
Each production technique has its advantages and disadvantages.
- Sintered magnets are the most common type and offer the highest magnetic strength, making them ideal for applications that require strong magnetic fields.
- Bonded magnets are less brittle than sintered magnets and we can produce them in complex shapes, but their magnetic strength is lower.
- Hot-pressed magnets have the highest magnetic strength of the three types, but they are expensive and can be challenging to manufacture in large quantities.
As a product designer, it’s essential to understand the differences between these neodymium magnets and choose the appropriate type for your application.
- Sintered magnets may be the best choice for applications requiring high magnetic strength.
- In contrast, bonded magnets may be better suited for complex shapes.
- Hot-pressed magnets may be appropriate for applications that require high magnetic strength and complex shapes. Still, they may not be cost-effective for all applications.
By considering the advantages and disadvantages of each production technique, product designers can make informed decisions about which type of neodymium magnet to use in their designs.
4. Magnetic assemblies
Magnetic assemblies are a combination of multiple magnets and other non-magnetic components together. They can form a complex magnetic system, offering magnetic features that are not available before. These assemblies can be used in various product designs and applications, offering unique advantages over individual magnets alone.
- For example, magnetic assemblies can provide increased holding force, precision alignment, or even act as a magnetic circuit by directing the magnetic field in a specific way.
- Some common examples of magnetic assemblies used in product design include magnetic clasps for handbags, magnetic door catches, and magnetic tool holders.
Magnetic assemblies can be custom-designed to meet specific product requirements, considering size, shape, strength, and magnetic field direction.
By utilizing magnetic assemblies in product design, manufacturers can improve product functionality, simplify assembly processes, and enhance overall product aesthetics.
5. Selecting magnets and placement
