Magnet injection molding also belongs to the category of metal insert molding. In the insert molding process, a ready-made, unmagnetized magnet insert is first put into a mold, and then molten plastic is injected into the mold cavity. Upon cooling and solidifying, a plastic metal compound product is ejected from the mold. https://www.cnmouldplastic.com/magnet-insert-molding/All Rights Reserved
