China-High-Precision-Injection-Molded-Magnet-in-Tiny-Size

Mingjie Magnet is an expert on manufacturing injection molded magnet, either neodymium + PPS magnet or ferrite + PPS (PA) magnet since year 1999.

By doing insert molding, magnetic material can be directly molded into or onto other assembly components without further assembly process

It is a new technology to achieve adjustable magnetic properties, composite molding, elastic magnetization and high mechanical strength

Injection molded magnets can be of very complex shapes with high precision, typically, tolerance is +/- 0.005mm, it is suitable for high precision parts

The material is harder to be cracked or chipped than sintered magnet.
