China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Magnets measuring 0.5–2 mm may appear to be merely small, but their actual production is by no means straightforward. The smaller the dimensions, the higher the demands tend to be in terms of machining, magnetisation, appearance and dimensional tolerances. For magnets used in certain electronic components, sensors and precision instruments, where space is inherently limited, standard sizes simply cannot fit; they must therefore be custom-made to suit the product’s specific design.
Common shapes for micro-precision magnets include cylinders, discs, cubes and rings, though they can also be manufactured to customer-provided drawings. For small-sized magnets such as 0.5 mm, 1 mm, 1.5 mm and 2 mm, the focus is not merely on achieving the correct dimensions, but also on considering magnetic strength, the direction of magnetisation and the actual assembly performance. It is also quite common for customers to bring in a sample and ask us to produce a new prototype that matches the original dimensions and magnetic properties.

When manufacturing miniature magnets, attention to detail during the production process is crucial. As the dimensions are so small, handling, machining and inspection become more challenging; if process control is inadequate, issues such as dimensional deviations, chipped edges or unstable magnetic properties are likely to arise. Therefore, before placing a custom order, it is advisable to clearly specify requirements such as the magnet’s length, diameter, thickness, polarity, quantity and operating environment. The more comprehensive the information provided, the smoother the prototyping and approval process will be.
NST Magnets has extensive experience in working with permanent magnet materials such as neodymium-iron-boron and ferrite, and also undertakes custom orders for various small-sized and non-standard magnets. For micro-precision magnets ranging from 0.5 to 2 mm, we can discuss dimensions, materials and magnetisation methods based on your specific product requirements.
