Currently, we have more than 10 types of raw materials and are able to produce 900 specifications of Ferrite Core for drive transformers, leading to a wide application in many industries.
Characteristics
1. To ensure great quality and high cost effectiveness, our company imported Toshiba kilns, Tamagawa presses and state-of-the-art CNC grinding machines, as well as brought in advanced sintering techniques and forming techniques. That's why we achieve an annual production of 12,000 tons.
2. In order for quality assurance, we selected reliable raw material manufacturers. Main ferric oxide suppliers include Japan JFE, Korea RG and China Steel Corporation. Main manganous-manganic oxide manufacturers are Hunan Special Metal Materials Factory and Kingray New Materials Science & Technology Co., Ltd.
3. We pay great attention to the product quality and carry out strict tests from raw material to final products. High-precision testing instruments include Bruker X-ray fluorescence spectrometer, high-frequency power dissipation measuring instrument, S4 PIONEER X-ray fluorescence spectrophotometer, etc.
Application: Drive transformers, high-frequency transformers, power inductors, high-frequency choke coils
