Problems solved by technology

Manual detection is labor-intensive and it is difficult to accurately detect each magnetic steel part, and there are probabilistic detection loopholes. After the detection of magnetic steel products, there will still be a certain number of defective magnetic steel products mixed with qualified magnetic steel. In the finished product, it will cause potential harm to the yield rate of coreless motor products
