Hand-Cranked EI Lamination Stacking Machine for EI 96 Series with Heavy-Duty Construction and Manual Operation

The EI 96 Hand-Cranked Lamination Stacking Machine is a precision-engineered manual device designed for the efficient assembly of EI-type silicon steel laminations into transformer cores. Tailored specifically for EI 96 series transformers, it is an ideal solution for small-to-medium batch production, prototype development, and maintenance workshops, combining reliability, simplicity, and cost-effectiveness.

Unlike automated machinery, this hand-cranked model eliminates complex power requirements and programming, making it accessible to operators of all skill levels while delivering consistent, high-quality stacking results.

• Reliable Manual Operation Equipped with a smooth, ergonomic handwheel, the machine delivers controlled, uniform pressure during the stacking process. This ensures laminations are fully and evenly inserted into the bobbin without gaps or misalignment, resulting in stable, noise-free transformer cores. The manual design also eliminates the risk of electrical faults, making it safe to use in any workshop environment.
• Wide Compatibility for EI 96 Applications Optimized for EI 96 standard silicon steel laminations, the machine supports common sheet thicknesses (0.30mm, 0.35mm, 0.50mm) and compatible bobbins. It works seamlessly with both cold-rolled and annealed electrical steel sheets, making it suitable for a wide range of low-frequency transformers used in power supplies, audio equipment, and industrial control systems.
• Heavy-Duty Construction for Long-Term Use The entire frame and working components are constructed from high-grade structural steel, with precision-machined guide rails and hardened contact surfaces. This robust build minimizes wear, maintains consistent alignment over years of use, and ensures the machine remains stable even during continuous daily operation.
• Improved Efficiency & Reduced Labor Costs Compared to manual hand-stacking, this machine significantly speeds up the assembly process while eliminating the need for rework caused by loose or uneven laminations. It ensures full insertion to the required stack height in one pass, reducing production time and labor fatigue for operators.
• Compact & Space-Saving Design With a sturdy, low-profile base and optimized footprint, the machine fits easily on standard workbenches, making it ideal for workshops with limited floor space. Its all-in-one design requires no complicated installation or setup, allowing operators to start production immediately.

This machine is widely used in:

• Small-scale transformer manufacturing facilities
• Electronic component assembly workshops
• R&D and prototype labs for new transformer designs
• Maintenance and repair workshops for power supply units
• Educational and training labs for electrical engineering
