SuperMagnetMan has been working with Injection Molding for many years, as evidenced by our own magnet pins and holding magnets.
Encapsulating plastic around all or a portion of a magnet is a possibility that has made customer designs a reality. There are considerations that must be understood prior to injection molding a magnet, specifically if the magnet will be able to be magnetized after injection molding, and the percentage of the magnet that will be surrounded by plastic. Our knowledge of the process can benefit you if injection molding magnets is a possibility.
If you would like us to review your design that includes injection molding, please contact us.
