The EI-133 automated stacking system, designed and built by liangui, is engineered for high-volume fabrication of EI-133 transformer cores. The machine runs on a PLC-based intelligent control architecture, ensuring user-friendly operation and dependable, consistent output. When compared to manually operated crank machines, this system multiplies throughput by a factor of eight to ten and raises core consistency above 95%, all while driving down labor requirements. It represents a fundamental production asset for mid-size and large transformer manufacturers.

Our stacking machines accommodate standard EI laminations across a wide envelope—from EI-19 through EI-300. Should your application require a dimension beyond this spectrum, please reach out to discuss tailored engineering solutions. The system processes lamination thicknesses from 0.3 mm to 0.5 mm, achieving stack rates up to 350 pieces per minute in either manual or automated mode, with interleaving fully maintained for superior core properties. We also supply bespoke OEM lamination dimensions aligned to your specific workflow.

• Independent Patent Portfolio

  The product is the result of internal R&D, and we own the complete set of patents and intellectual property rights covering both the external design and the internal core mechanism.

• Jam-Resistant Operation

  Built specifically to address the sector-wide challenge of material jamming during stacking, this machine delivers markedly smoother, interruption-free production. Fewer stoppages and less troubleshooting translate directly into higher overall output.

• Intuitive PLC Control System

  A touch-screen PLC interface makes parameter configuration straightforward. Operators can freely set stacking speed, target piece count, and other critical process variables to suit real-time shop floor demands.

• Accelerated Throughput

  Running at a top adjustable speed of 12 pieces per second, the system achieves twice the output of traditional hand-operated machines, and it drastically reduces time spent on sheet loading.

• Minimal Training Requirement

  The learning curve is extremely short. New team members need only grasp sheet replenishment and the startup sequence; most are fully productive after a 15-minute orientation.

• Durable Construction

  Every unit is assembled from premium-grade materials and components. A 12-month warranty comes standard, and we offer a satisfaction-guaranteed return policy at any time.

• Proven Safety Track Record

  With over 2,000 installations across China and more than a decade of field operation, the machine has maintained a flawless safety history with zero recorded incidents. For environments demanding heightened protection, optional add-ons like extra guarding and safety light curtains are available.

• Exceptional Precision & Consistent Results

  Cores produced on our stackers achieve a stacking accuracy within 0.05 mm and a stacking factor no less than 97%. Core loss is kept to just 1.3 W/kg (measured at 1.7 T, 50 Hz), and the no-load current of finished transformers remains under 0.5% of the rated value. Batch-to-batch variation is held tightly within ±2%.
