Ferrite Core for High-Frequency Transformer, EIF
Magnetic Powder Core, Ferrite Core, Magnetic Component
<start> <p>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.</p>
<p><strong>Characteristics</strong><br />
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.<br />
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.<br />
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.</p>
<p><strong>Application:</strong> Drive transformers, high-frequency transformers, power inductors, high-frequency choke coils</p>
