Chemistry of Soft ferrites:

Hinoday’s wide ranges of soft ferrite cores are made from Manganese Zinc Ferrite (MnZnFe12O9). Mn-Zn ferrites have Inverse Spinel structure resulting to the magnificent magnetic properties. The cubic crystal structure enables MnZn Ferrite to show isotropic crystalline properties leading to low coercive force and lower power loss. Chemistry of various soft ferrite grades are closely controlled by using X-ray Fluorescence Spectrometer (XRF).

Process of Ferrite magnet manufacturing:

Ferrite manufacturing is based on Ceramic Powder Technology. High quality Iron oxide, Manganese oxide and Zinc Oxide are homogenously mixed and reacted at controlled high temperature. The ferrite granules are crushed and consequently converted into ready to press powder by spray drying process. Powder compaction is done using precision presses. Sintering to achieve the required density, magnetic and dimensional features are done in precisely controlled furnaces. Sintered Ferrites are ground to achieve the required dimensions in close tolerances.

Quality System:

We are committed to quality and our quality policy is customer centered. Magnet manufacturing is supported by highest quality system, ISO-TS16948. Control Plans, APQP, PPAP, FMEA, Continuous Improvement, 8D problem analysis are inherent to Hinoday’s manufacturing.

Technology:

Ferrite core manufacturing is based on Ceramic Technology. Hinoday’s manufacturing is fully integrated with its R&D division and introduce technological advancements in the areas of process, products and new ferrite grades.

Ferrite Grades:

Hinoday is offers most of the Soft Ferrite grades required to meet customer demand for across-the-board ferrite core requirements for applications such as – SMPS and other Transformers, telecommunication, RFID, Antenna, Compact Fluorescent Lamps(CFL), Electrode less Lamps (ELL).
