Why Choose the SD-LS250 Vertical Stacker for Your Pharmaceutical Packing Equipment Line

As a leading manufacturer of advanced pharmaceutical packing equipment, we proudly introduce the SD-LS250 Vertical Stacker—a game-changer for pharmaceutical insert and outsert systems. Designed to integrate seamlessly with paper folding machines and buckle folding machines, this innovation elevates efficiency and precision in drug packaging workflows.

Unmatched Capacity & Precision

With an industry-leading thickness range of 1-16mm (the widest globally), the SD-LS250 accommodates diverse packaging demands. Its motor-controlled lifting system ensures smooth, stable stacking, while the unique slope-angle design prevents product deformation—critical for meeting stringent requirements of automated pharmaceutical packing equipment.

Smart Control & Seamless Integration

The intuitive human-machine interface simplifies setup and monitoring. Control Page 1 displays real-time operational data, while the alarm page offers clear visual alerts for faster troubleshooting. Through RS485 communication, the stacker syncs effortlessly with SPEED folding machines or parallel knife folders, enabling bidirectional control. The "smart one-touch learning" feature automates adjustments, reducing downtime and boosting productivity.

Built for Speed & Reliability

Compatible with high-speed SPEED folders and buckle folding machines, the SD-LS250 ensures uninterrupted workflows in fast-paced environments. Its robust design and error-proof operation make it ideal for pharmaceutical insert and outsert systems requiring zero-defect outputs.
