JinMa focuses on the development and production of silicon steel transformer cores, providing practical magnetic material solutions for a wide range of applications. Drawing on years of experience in material selection and processing, we apply proven lamination and winding methods in our manufacturing process. Our product range includes C-type, U-type, E-type, and UI/EI-type cores, along with high-flux toroidal and rectangular cores, as well as designs for both single-phase and three-phase systems.
You will find these cores at work in everything from factory automation and power transmission to precision tools and renewable energy setups. They are a common sight in urban power grids, solar inverters, high-end audio gear, and rail transit systems. We focus heavily on manufacturing precision to keep core losses and electromagnetic noise as low as possible, ensuring our parts are both reliable and easy to customize for specific projects. Our goal is to push for better energy efficiency while supporting the expansion of advanced manufacturing on a global scale.
