STACKING · SRDZ SERIES

Intelligent Core Stacking Line

Robotic lamination stacking with linear-motor gantries: 4,000-6,000 sheets per hour, joint gaps held under 0.3 mm, and automatic centre-limb angle correction – the manual bottleneck after your cutting line, automated.

Why stacking is worth automating

Linear-motor gantry, 3 m/s

Pick-and-place carriages ride linear motors – no racks to wear, top speed 3 m/s, and positioning that stays accurate over years.

Joint gap under 0.3 mm

Servo alignment stations position centre limbs, side limbs and yokes; automatic angle correction keeps step-lap joints tight – lower loss and noise in the finished core.

4+ cores per 10-hour shift

Around 5,000 sheets per core: one line replaces a stacking crew, with load-in and load-out under 20 minutes per core.

Proven brand components

Yaskawa control and linear motors, Siemens and Schneider low-voltage electrics, SMC pneumatics, HIWIN guideways.

Planning cut-and-stack as one system?

Automatic stacking changes how your cutting line should be configured – symmetric V-notching, stacking-friendly collation. Plan both together.
