[0002] Permanent magnets refer to magnets that can retain high remanence for a long time in an open circuit state, such as natural magnets (magnetite) and artificial magnets (aluminum-nickel-cobalt alloys). In addition to permanent magnets, there are also electromagnets that need to be powered to be magnetic. Permanent magnets are also called hard magnets, which are not easy to lose magnetism or be magnetized. However, if the permanent magnet is heated above the Curie temperature, or is placed in an environment with a reverse high magnetic field strength, its magnetism will also decrease or disappear. Some magnets are brittle and may break at high temperatures.

In the current use of injection molds, it is mainly a series of processes of manual tightening, injection molding, unlocking, and taking out the finished product. However, permanent magnets are melted and cast at extremely high temperatures. A series of manual assembly and disassembly of molds make operators extremely vulnerable to high temperature injuries.
