Complete Guide OF Injection Molded NdFeB Magnets NdFeB magnets are widely used because of their excellent magnetic performance. Among various molding methods, injection molding is an important process for producing complex structures and precision magnetic components. It combines magnetic powder with thermoplastic resin and uses injection molding equipment to form the product. This process combines [...]
Injection Molded vs. Sintered Ferrite Ring Magnets Injection molded ferrite ring magnets and sintered ferrite ring magnets are both commonly used permanent magnet components in motors. However, they have clear differences due to their different manufacturing processes and material structures. In comparison, injection molded ferrite ring magnets focus more on design flexibility and production efficiency, [...]
Injection Molded Ferrite Ring Magnets for Fan Motors Injection molded ferrite ring magntes are commonly used as permanent magnetic components in fan motor rotors. They are widely used in table fans, pedestal fans, wall fans, ceiling fans, and other fan motor products. Compared with other magnetic material solutions, injection molded ferrite rings offer advantages in [...]
Wet Press vs Dry Press Ferrite Magnets Permanent ferrite magnets can be divided into two manufacturing processes based on their forming methods: wet pressing and dry pressing.The forming process not only affects the internal grain orientation and magnetic performance of ferrite magnets, but also influences production efficiency, dimensional control, and final application performance.Understanding the differences [...]
How to Identify the North and South Poles of Arc Magnets? Arc magnets, also known as curved magnets or tile magnets, are one of the most widely used magnet types in motors. Their unique curved design allows them to fit the rotor or stator more effectively, making them an essential component in various motor applications. [...]
Magnet Temperature Limits: Maximum Operating Temperature vs Curie Temperature Temperature is one of the key factors affecting the performance and reliability of permanent magnets. Beyond a certain temperature threshold, magnets may even undergo irreversible demagnetization. Therefore, understanding the temperature limitations of magnets is crucial when selecting suitable magnet materials for specific applications. When evaluating the [...]
Is Steel Magnetic? Ever held a magnet up to different metal objects and wondered why it sticks to some but not others? Most steel IS magnetic because it contains iron—but not all steel behaves the same way around magnets. Some types like austenitic stainless steel (304, 316) won’t attract magnets at all, while carbon steel [...]
Can Copper Be Magnetised Pure copper cannot be permanently magnetized because it is a diamagnetic material with paired electrons that repel magnetic fields. Copper is different from iron or nickel because it doesn’t have the atomic structure needed for ferromagnetism or permanent magnetism. Let me clear something up right away. If you’re picturing a copper [...]
N52 vs N54 vs N55 Magnets: Choosing the Right Grade for Performance, Cost and Temperature So you’re shopping for neodymium magnets and you keep seeing these grades: N52, N54, N55. Which one should you choose? And more importantly, does that higher number actually mean better performance for your project? Let me break it down for [...]
NO Export License Needed! Dy / Tb / Sm-Free NdFeB Magnets Hey there, sourcing managers and engineers, We are handling international sales at MPCO Magnets. We talk to buyers every day, and one question comes up constantly: “Do you have the rare earth export license?” Our answer is always the same, and it’s a good [...]
Are Batteries Magnetic Are batteries magnetic? The short answer: Batteries themselves aren’t magnets, but many batteries ARE attracted to magnets. There’s a big difference between those two things, and I’ll explain exactly why in this guide. In this post, as a professional neodymium magnets manufacturer, I’ll also show you: Which battery types stick to magnets [...]
Are Magnets Bad for Batteries? Are magnets bad for batteries? The short answer is no — magnets won’t damage your batteries or drain their charge. But there are 2 catches: Short circuits from conductive magnets touching battery terminals and physical damage from strong magnets impacting battery casings. As a professional neodymium magnets manufacturer, let me [...]
