INDUCTOR DEVICES AND FORMING METHODS THEREOF

Abstract: the present disclosure relates to the field of inductor, specifically to an inductor device and a forming method thereof. a coil and a magnetic core are secured through a primary injection molding process to form a primary molded body, which is then fixed with an insert to form the inductor device. compared to current encapsulation molding process, the present application adopts a novel injection molding technique that offers higher molding efficiency. additionally, by employing a two-stage injection molding process, the molding material can more easily penetrate into smaller gaps, ensuring more thorough filling at the corners and edges. this method also helps to reduce injection pressure, thereby decreasing the impact force on the magnetic core and lowering the risk of cracking or damage to the magnetic core.
