According the process way of bonded magnet, there is Bonded compression NdFeB and Bonded Injection NdFeB
Features:
Process size of shrinkage rate is small, only 0.2%-0.5%,No distortion, no second processing and get products with High - precision, mechanical strength is well.
Easy for mass production with many kinds of sizes, especially for small sizes products.good cost performance.
