Dongguan Jiarun Yaoguang Industry Co., Ltd. was established in August 1997 and is strategically located in Shipai Town, Dongguan City. Over the decades, our manufacturing base has expanded to cover an area of 10,000 square meters, backed by a robust foundation of about 50 million total investment. Operating as a national high-tech enterprise with 26 years of dedicated experience, we possess the comprehensive capability to meet the demanding requirements of both manufacturing complex moulds and producing precision stamping products. By securing the ISO-9001: 2008 quality system certification ahead of our peers, we have cemented our position as a premier motor core mould manufacturer within the motor industry of South China. Our facility is outfitted with excellent equipment, the majority of which are introduced directly from industry-leading manufacturers in Taiwan, Japan, and Switzerland, ensuring that every stator and rotor core we produce meets exact dimensional tolerances.
The foundation of an efficient motor lies in its raw materials. Our auto motor stator rotor cores are constructed using carefully selected laminated silicon steel paired with high-conductivity copper or aluminum materials. This specific material composition is engineered to significantly reduce eddy current loss during electromagnetic conversion. When handling the raw laminations, one can immediately notice the uniform metallic sheen and the exceptionally smooth, burr-free edges—a direct result of our precision stamping process. This clean finish prevents micro-arcing between layers, thereby elevating the overall energy efficiency of the assembled motor and keeping operating temperatures strictly within safe thresholds.
Specializing in motor lamination core moulds and a wide variety of metal hardware parts moulds, our production lines are designed for ultimate flexibility and precision. The moulds we produce can meet the diverse demands of single sheet stamping, automatic stacking, and highly specialized rotary 30-180 degree stacking. By utilizing rotary stacking techniques, we effectively neutralize any microscopic thickness variations in the raw steel sheets, resulting in a perfectly balanced, weighty, and solid core assembly. Furthermore, we accommodate pieces stacking and lead the way in designing hydraulic systems and automatic rolling moulds for DC motors. This level of mechanical precision ensures that the stator and rotor interlock with minimal air gap variance, translating to smoother, quieter motor operation.
For procurement teams and technical engineers, the true value of a motor core lies in its operational reliability and energy performance. By optimizing the magnetic circuit design and applying advanced insulation treatments, our stator and rotor cores can support motor running efficiencies exceeding 95%. This substantial leap in efficiency directly reduces long-term running costs and energy consumption for the end-user.
Thermal Stress Resilience: Each batch undergoes rigorous insulation and thermal stress testing to ensure the cores maintain structural integrity and magnetic permeability even under complex, high-temperature working conditions.
Strict Tolerance Control: The automated stamping and stacking processes guarantee that every unit replicates the exact geometric specifications of the prototype, eliminating mechanical vibration.
Operational Philosophy: The company is adhering to the concept of meticulousity, stability, efficience, and initiative creation, ensuring every core performs reliably over an extended lifecycle.
We are intensely customer-oriented, continuously improving quality to provide our partners with high cost-performance tooling and flexible production scaling. Whether you require initial prototype development or large-scale mass production, our facility is equipped to deliver. In recent years, the new energy vehicle motor (EV) has become our primary research and develop product, demanding the highest levels of magnetic efficiency and structural durability. Beyond EV applications, these stator and rotor cores are widely adapted for generators, industrial automation equipment, and heavy-duty DC motors.
Our manufacturing expertise extends beyond just the core. We are highly proficient at manufacturing moulds for metal deep drawn parts, motor housing, motor metal brackets, and metal terminal parts, allowing us to supply comprehensive hardware solutions for motor assemblies. Operating under a standard modern management system, we deliver high-quality products backed by good after-sales service. This commitment has enabled us to establish long-term business relationships with a lot of famous enterprises domestically, as well as in Germany, Japan, France, Italy, India, Vietnam, Malaysia, and across Southeast Asia. Through relentless dedication to engineering excellence, Jiarun receives consistent high praise in the motor industry.
