Vacuum Suction Cups vs. Mechanical Clamps for Panel Material Handling

Published on 2026-09-10 by Shunxin Automation Engineering Team

Preventing Edge & Surface Defacing

Traditional mechanical grippers clamp workpiece perimeters with pneumatic jaws, frequently chipping brittle melamine edges or leaving pressure dents.

Advantages of Vacuum Suction Handling

  • Distributed Load: Multi-zone silicone vacuum cups distribute holding force across the panel face, safely handling thin 9mm panels without warpage.
  • Venturi Ejectors vs. Vacuum Pumps: Shunxin gantry stackers combine high-flow vacuum blowers with quick-release atmospheric purge valves for instant sheet drop-off.
