High-Speed Transformer Core Lamination Production Line
7
The JY-600 Double Shear Three Punch Cut-to-Length Line (Reverse Stacking Type) is a high-performance automatic production system specially designed for processing grain-oriented silicon steel coils into precision transformer core laminations.
This advanced transformer core production line integrates feeding, dual V-notching, hole punching, angle shearing, automatic sorting, and reverse magnetic stacking into one continuous workflow, delivering high efficiency, excellent accuracy, and stable industrial performance.
It is widely used for producing:
Step-lap transformer cores
Full miter laminations
Half miter transformer sheets
Straight joint transformer laminations
