CRGO Core Lamination & Cutting Line SRJD400-214G
SRJD400-214G
An intelligent CRGO core lamination & cutting line integrating unwinding, feeding, punching/notching, pin-positioning pre-stacking and dual-robot core lamination. It can laminate two CRGO cores simultaneously in full “H” shape or “E+I” shape.
Proven in Production
Stability You Can Build Your Line Around
Performance that holds up long after installation
4-Head Hydraulic Decoiler
Load four coil widths at once with hydraulic tensioning and infrared centering—no pit required.Centralized 7-Tool Cutting
2 shearing + 1 V-notching + 4 hole-punching tools operate synchronously for maximum throughput.Servo-Driven Precision
V-notching moves in X/Y axes; hole punching auto-positions by sheet length for repeatable accuracy.Smart Pre-Stacking
Magnetic reverse suction with photoelectric monitoring catches fly-outs and mis-drops automatically.Dual-Robot Lamination
Two robots alternate between left/right tables—no line stoppage during core changeover.Remote Diagnostics
Online program upgrades and air-conditioned control cabinet keep electronics reliable year-round.
