Isotropic Bonded Neodymium Magnet Particles NdFeB Granules Injection NdFeB Compound

Process flow

1. Use NdFeB magnetic powder to mix with PA6 or PA12 or PPS or EPA, antioxidants and lubricants, and form pellets in a screw extruder
2.The granules are sieved and weighed, and the properties are measured and then packed into buckets or bags, and packed on pallets

Application

Injection molding NdFeB compouds are a kind of bonded NdFeB products, and are suitable for products formed by injection molding machines. Because of the high precision of injection molding and integrated molding with copper, stainless steel, plastic bearings and other types of inlays, It can be used in micro motors, motor rotors and sensors, automotive motors, and can also be used in household appliances and toys

Feature

Advantages of precise dimensions, light weight, thin walls and complex shapes
Stable magnetic properties, can be bonded together with other metal parts
In many electronic products with high precision and high performance requirements, injection molding magnets can meet their requirements
