Vacuum suction is a core solution for "flexible grasping" in industrial automation with four core advantages: non-damaging grasping, adaptability to multi-material/irregular workpieces, clean and environmental protection, and flexible operation. It can be adapted to different industry characteristics of workpieces (thin/thick, precision/coarse, sanitary/standard).
Bellows 2.5-stage Vacuum Suction Cups ZP3P-JT
For Bellows 2.5-stage Vacuum Suction Cups ZP3P-JT are specialized for high-precision handling of thin, flexible, and easily deformable materials. They are widely applied in automated packaging lines for food, medical, and consumer products, enabling stable gripping of film bags, plastic sheets, and soft packaging. With a flexible sealing lip and hygienic silicone materials, they ensure consistent adhesion, reduce deformation, and support clean, efficient operation in high-speed automation environments.
