As is well known, it is widely used. However, it also has special characteristics, such as magnets that cannot be attacked and cannot be used at high temperatures. So, how should we avoid these problems when using magnets? For example, what details do we need to pay attention to when using magnets in injection molding? We all know that injection molding requires molding at high temperatures, and only after high-temperature molding can the injection molded parts come out. In this case, if the magnet is placed on the injection molded component and molded together, the magnet will easily demagnetize or even become demagnetized. For this situation, our professional magnet manufacturer believes that we can solve this problem in two ways. Firstly, use high-temperature resistant magnetic materials instead of ordinary neodymium iron boron strong magnets. Secondly, by using high-temperature molds, there is a space for magnets to be placed on the injection molded parts. By using these two methods, we can avoid demagnetization of the magnet during the use of injection molded parts.
