Matters needing attention in the use of magnets on injection molded parts

   It is well known that magnets are widely used. But magnets are also special. For example, magnets cannot be attacked and cannot be used at high temperatures. So, how should we avoid such problems when applying magnets?

   For example, what details do we need to pay attention to when using magnets in injection molding? We all know that injection molding needs to be formed by high temperature. Only after high temperature molding, the injection molded parts will come out. In this case, if the magnet is placed on the injection molded part and molded together, then the magnet is easily demagnetized or even demagnetized. For this situation, our professional magnet manufacturers believe that we can solve this problem in two ways. First, use high-temperature-resistant magnetic materials to replace ordinary NdFeB strong magnets; second, through high-temperature molds, there is a place for magnets on the injection molded parts. These two methods are used to avoid demagnetization of the magnet when the injection molded part is used.
