The EI-48 automatic lamination stacking machine is engineered for high-volume production of EI-48 low-frequency transformer cores. It precisely inserts E & I silicon steel laminations into transformer coil bobbins under PLC control, completing the core assembly process with exceptional accuracy and consistency. Compared with manual operation, it improves production efficiency by 8-10 times and raises core consistency above 95%, making it the core production equipment for small and medium-sized transformer manufacturers.
