Our team walks you through how the EI-19 automatic lamination stacking machine performs in real miniature transformer production. In this video, you'll see E & I silicon steel laminations inserted into cardboard and plastic bobbins under PLC control, with ±0.1 mm stacking accuracy at up to 250 stacks per minute. We demonstrate changeover, touch screen recipe setup, jam detection, and gentle handling of 0.3 mm thin laminations — giving B2B buyers a clear, practical look at core assembly for 0.5–3 VA transformers and chokes.
