Whether by phone or WeChat, I found that many of the motor customers who inquire about injection molded magnets are inquiring about injection molded ferrite magnets, while inquiries about injection molded neodymium iron boron are relatively few. When searching for injection molded neodymium iron boron manufacturers, I did not find an official website specializing in injection molded neodymium iron boron, indicating that the overall demand for such magnets is low, Today, let's talk about why most customers choose to inject ferrite instead of neodymium iron boron.

1、 Lower cost of injection molded ferrite

Injection molded ferrite magnets

Both injection molded ferrite and injection molded neodymium iron boron require molds or openings, and the cost of injection molded neodymium iron boron is higher. Therefore, in order to save costs, enterprises do not choose to use injection molded neodymium iron boron.

2、 Injection molded ferrite has better temperature resistance

The combination of ferrite powder and nylon 6 or PPS can pass the test at 180 ℃, while neodymium iron boron magnetic powder above 120 ℃ will show significant irreversible loss in the magnetic properties of the material.

3、 Injection molded ferrite magnetic properties can meet customer needs

This is also a crucial reason, as many customers do not have such high requirements for the magnetic force of the magnet. They can only meet the requirements of induction, speed measurement, and so on.
