Custom molding instructions for silicone magnet
This silicone magnet is an integrated overmolding of silicone + magnet, which is to treat the surface of the magnet specially, place it into the silicone molding mold, then put in the silicone raw material, and after a period of high temperature and high pressure, make the silicone and magnet closely combined into one.
Due to the fact that during the integrated overmolding process of silicone + magnet, the temperature of the mold and raw materials generally exceeds 160°C, the magnet will lose its magnetism at this temperature. Moreover, the silicone molding mold is made of steel with good magnetic conductivity, making it difficult for magnetic magnets to be positioned stably in the mold. Therefore, non-magnetic magnet blanks must be used during the integrated overmolding process of silicone + magnet, and after the rubber coating is completed, the magnet is magnetized.
According to your usage requirements, when customizing a Silicone Magnet, you can choose to completely coat the magnet with a silicone layer, or opt for partial coverage of the magnet with a silicone layer. The shape, size, color, hardness, and printed icons of the silicone coating layer can all be customized.
If the magnet surface is to be completely wrapped with a silicone layer, neodymium magnets or ferrite magnets can be used. If only partial coverage of the silicone layer on the magnet is needed, neodymium magnets or steel magnets are usually recommended.
Silicone + magnet integrated overmolding is a relatively complex process. Even if you have completed the product design, we may propose some modifications and optimization suggestions based on the product’s shape, structure, materials, and usage requirements during the custom mold opening process, in order to successfully achieve silicone + magnet integrated overmolding. Therefore, we recommend that you keep in touch with us in a timely manner during the design process.
