Caution on the use of magnets in injection molding parts

- Jul 25, 2019-

We all know that magnets are widely used. But magnets have their own peculiarities, for example, they can't be slammed, they can't be used at high temperatures. So how can we avoid this problem when using magnets?


What details do we need to pay attention to when using magnets in injection molding? Injection molding we all know that it needs to be formed by high temperature, only after high temperature molding, injection parts will come out. In this case, if the magnet is placed on top of the injection molding piece and molded together, the magnet can easily be demagnetized or even gone. For this situation, our professional magnet manufacturers believe that we can solve this problem in two ways. First, use high-temperature magnetic material instead of ordinary ndfeb strong magnet; Second, through the high temperature mold, there is a place for the magnet on the injection parts. Through these two ways to avoid the use of magnets in injection parts when the magnet demagnetization.
