Room temperature pressed and hot pressed methods are two kinds of production methods in which spot welded semi-finished products and finished powder are integrated into a mold during the production proces.
Room temperature pressed method is currently the most common production method for integrated inductors, which is carried out at room temperature of 25 ℃ and pressure is often between 5.0~9.0 T/cm2.
Hot pressing refers to the process of controlling temperature and pressure to achieve integrated forming of inductors through powder casting, connection, and packaging at high temperatures (usually above 100 ℃) and low pressures. Hot pressing has low molding pressure, and the pressure that the coil withstand is only 35% - 48% of traditional room temperature pressing technology, greatly reducing coil deformation, improving the reliability and stability of the circuit, and also significantly reducing the overall loss of inductance.
Through years of technical research, CODACA Electronics has mastered the independent development technology of magnetic core materials and the production process of hot pressed integrated inductors, and has applied it to the research and production of automotive grade molded inductors. Its representative products mainly include automotive grade Molding Power Choke VSHB, VSHB-T, VSEB-H and other series.
