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
- The properties of anisotropic PPS NdFeB pellets are close to that of molded NdFeB magnets and can be used for high-performance magnets. At the same time, PPS has a temperature resistance of 200 degrees and is resistant to acid, alkali and salt environments.
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
