Disc Magnets

Introduction

According to different shapes, our products are square magnets, disc magnets, cylinder magnets, etc. These magnet products are either neodymium magnets or ferrite magnets. Besides, we also manufacture custom magnets in various shapes required by customers. With advanced equipments, our magnets are accurately processed. Apart from custom magnets and common magnets such as square magnet, disc magnets, etc., we can also produce micro-magnets and other magnets which are complex in structure.

Features

Neodymium magnets are featured by large remanence, high coercivity, large magnetic energy product, high cost performance ratio, etc. Apart from disc magnets, we also provide custom NIB magnets. Ferrite magnets are easy to reach magnetic saturation. Besides, they are featured with high temperature resistance, high cost performance ratio, high magnetic permeability and obvious brittleness. We can manufacture various shapes of ferromagnets, too.

Application of Disc Magnets

Magnets manufactured by us, including NIB magnets and ferromagnets, are widely used in many industrial products, such as sensors, motors, rotors, wind turbines, wind generators, speakers, loudspeakers, magnetic hooks, magnetic holder, filters automobiles, and so on. There is a list for reference as follows.

Notes

1. Keep ferrite magnets and NdFeB magnets away from people who are using cardiac pacemakers or other medical devices, because magnets may cause malfunction of medical devices, threatening life of these people.
2. Keep magnets away from magnetic recording media and other devices sensitive to magnetism, such as magnetic card, hard disk drive, watch, etc.
3. Clean out disc magnets during installation, because magnetic chippings may arise when two magnets crash to each other.
4. Take care when using a bulky neodymium magnet or ferromagnet which is of strong magnetism, because it can cause damage to machineries or hurt people.

Separate Two Magnets

If two disc magnets are tightly attached to each other, do not pull them directly apart, no matter they are ferrite magnets or NIB magnets, instead, you just need quite a bit of force which is equal to the magnetism to push them apart. Details are as follows:
(1) Hold one magnet in your left hand, and move the other magnet in horizontal direction with index finger and thumb of your right hand. Then, the two magnets are pushed apart.
(2) After two disc magnets are separated, do not put any magnet onto other magnets to prevent them from being attracted tightly again. Instead, you should put each magnet away from other magnets or iron items (about 16 cm away), or, you can cover the separated magnet with thick paper. If you want to put one magnet back into the other magnet, you should slowly move it back from the edge to the deepest part of the other magnet. Above operations should be handled gently, besides, make sure that your hands hold ferrite magnets or NdFeB magnets tightly.
Since its foundation in 1990, Lantoky Magnetic Device Factory has developed into a specialist manufacturer of permanent magnet assemblies, including disc magnets like neodymium magnets and ferromagnets. In 1996, we established branch a branch factory in Jiangmen, Guangzhou province. In 2001 and 2006, we updated our factories and facilities. Our products have passed ISO9001-2008, ISO14001-2004 and GB/T28001-2007. Besides, these products, including permanent ferrite magnets and rare earth magnets, are produced under stipulations of ROHS (Restriction of Hazardous Substances).
