Are there many injection molded neodymium materials used in air conditioning?

When it comes to magnets used in air conditioners, many people's first reaction may be ordinary neodymium iron boron magnets, but in fact, with the increasing miniaturization and intelligence of air conditioning products, injection molded neodymium iron boron has also begun to have certain applications. Compared with traditional sintered neodymium iron boron, its biggest feature is good size consistency, flexible shape, and the ability to directly make complex structures such as holes, teeth, rings, etc.

One of the common application directions of injection molded ndfeb in air conditioning products is in motors and sensors. For example, magnetic materials may be required for fan motors, swing mechanisms, and motor rotors in air conditioners. Especially for components that require volume, weight, and assembly accuracy, injection molding neodymium iron boron can be combined with plastic structures to reduce subsequent assembly processes. For some small motors, the magnetic rings and magnets themselves are not large in size, but they have high requirements for magnetic performance, dimensional accuracy, and pole number. This is also where injection molded magnets are more suitable for playing a role.

So, are there many injection molded neodymium iron boron materials used in air conditioners?

From the current application perspective, it is useful, but not too much. There are many types of magnets involved in air conditioning, and different components have different requirements for magnetic performance, temperature resistance, cost, and processing methods. Some parts use sintered neodymium iron boron, some use ferrite, and some small, irregular or plastic integrated parts are more suitable for injection molding neodymium iron boron.

If it is a project involving air conditioning motors, swing motors, sensors, etc., customized injection molded neodymium iron boron magnetic rings or magnets are required. It is best to provide the magnet manufacturer with the drawings, dimensions, magnetic properties, and working temperature requirements in the early stage, and then select suitable materials according to actual needs.
