The current production process of permanent magnet ferrite in the company is as follows: purchasing raw materials, mixing pre burned materials purchased from external sources with their own formula and ingredients, ball milling them in a ball mill, precipitating them in a storage tower, and then producing ferrite products through forming, pressing, sintering, post-processing, and other steps. Finally, after sorting, magnetizing, packaging, warehousing, and outbound steps, high-quality permanent magnet ferrite products are delivered to customers.
