Injection Molded Samarium Cobalt Bonded Magnets can be made by combining SmCo powders with Nylon 6, Nylon 12, PPS and other resins. The ratios between magnetic powders and resins are endless, therefore many grades exist depending on magnetic performance, temperature resistance, and mechanical strength. These materials can be molded directly over or into another polymer or metal component. The shapes and sizes are endless, as are the magnetization patterns that can be achieved either in the molding tool or by utilizing a magnetizing fixture. The following tables list several common grades, however we have the capability to formulate any desired grade of magnetic material based on customer specified parameters.
