Automatic EI-60 Lamination Stacking Machine for Control and Distribution Transformer Core Assembly, ±0.1 mm Accuracy, 250 Stacks/Min, PLC Control, CE

Automatic EI-60 Lamination Stacking Machine for Transformer Core Assembly

The EI-60 automatic lamination stacking machine inserts E & I silicon steel laminations into transformer coil bobbins under PLC control. Sitting between the compact EI-57 and the larger EI-66 platform, the EI-60 covers 40-120 VA control and distribution transformer cores, holding a stacking accuracy of ±0.1 mm at speeds up to 250 stacks per minute. It replaces manual stacking with a station that keeps producing shift after shift.

Built for Multi-Shift Production

Most stacking machines look good in a demonstration. The real test is the third shift, six months in. The EI-60 is engineered around that reality: a mechanically simple insertion path means fewer wear points, the PLC monitors every cycle and stops the machine the moment a lamination misfeeds, and all routine service points stay reachable without dismantling the machine. The result is a stacking station that holds its accuracy across long production runs instead of drifting as the day goes on.

Key Specifications

Uptime by Design

✅ Continuous-Duty Insertion Path – A simplified, low-wear lamination transport keeps cycle times stable from the first stack of the shift to the last.

✅ Automatic Jam Detection & Stop – The PLC halts the cycle immediately on a misfeed, protecting both the lamination stack and the tooling before damage occurs.

✅ Fast Core Changeover – Switch between EI-60 core sizes in minutes from the touch screen; no mechanical re-tooling marathon between jobs.

✅ Serviceable in Place – Routine checks on the insertion head and feed path are reachable from the front of the machine, so maintenance does not require a teardown.

✅ Consistent Stacking Compression – Uniform stacking force keeps the effective air gap stable, which keeps core loss and audible hum predictable batch to batch.

✅ Gentle on Thin Laminations – Handles 0.3 mm, 0.35 mm and 0.5 mm EI silicon steel sheets without edge damage or deformation.

✅ Low Power, Quiet Motion – 30-60 W power draw and smooth mechanical action suit it to electronics assembly floors.

✅ Safe by Standard – Dual grounding, overload and short-circuit protection, emergency stop and guarded moving parts.

Where the EI-60 Fits in Your Line

Sized for 40-120 VA cores, the EI-60 suits manufacturers of control transformers, distribution and isolation transformers, power supply and adapter transformers, instrument transformers, and general-purpose EI cores for industrial electronics. It works equally well as a standalone stacking station or as part of a winding and assembly cell, and accepts both cardboard and plastic bobbins.
