Magnetic Assemblies
 Besides the magnetic assemblies listed on our products catalogue, we are always ready to design and manufacture other magnetic holding assemblies with special specifications according to customers’ requirements, drawings and samples.
 Magnetic assemblies are consists of several materials, besides the magnet. It is usually combined with metal which will be much powerful than individual magnets. They are widely applied in industrial processing like construction, engineering, automotive, electronic and agricultural, etc. Magnet assemblies are used for mounting, lifting, holding, fixing and transferring objects, such as pot magnet, magnetic tool bar, magnetic catchers, Lifting Magnet etc.
When selecting magnet assemblies, consider the environment in which the assembly will be used, like temperature. What is the holding force needed based on the size and weight of the parts involved and how will the assembly be secured, whether bolted, mounted, fastened or adhered? Also, consider the shape of the magnet desired (e.g. disc, ring, rectangle, etc.) and the size, including diameter, length, width and height. Knowing what variation in dimensions is allowed (tolerances) is important. Price and quantity are also considerations.
