Wuxi LLS Metal Products Co., Ltd.

Precision motor cores and silicon steel laminations form the manufacturing focus of Wuxi LLS Metal Products Co., Ltd. The company produces stator cores, rotor cores, EV stator cores, BLDC stator cores, and custom cores for electric vehicles, servo motors, industrial motors, generators, and eMobility applications. Its engineering workflow covers tooling design, progressive dies, high speed stamping, laser cutting for prototypes, automatic stacking, interlock punching, laser welding, and adhesive bonding. Silicon steel sheets from 0.2 mm to 0.5 mm are processed to meet specified magnetic properties, core loss targets, slot geometries, and dimensional requirements. Custom projects receive feasibility evaluations and production quotations based on submitted CAD data.

Quality control extends from incoming electrical steel verification through final inspection and performance testing. Material checks cover grade, thickness, coating, surface condition, and magnetic properties, while dimensional inspection addresses inner and outer diameters, slot geometry, stack height, flatness, roundness, concentricity, and burr height. Coordinate measuring machines, vision systems, precision gauges, core loss testers, weld inspection equipment, and bond strength testing equipment support process verification. Inspection records provide traceability, and reports can be prepared according to customer requirements. The ISO 9001 certified quality system combines customer drawings, agreed tolerances, joining criteria, visual checks, and magnetic testing to maintain consistent production across prototype and volume requirements.
