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 5.5-stage Vacuum Suction Cups ZP3P-JT
We invite you to select from our factory's Bellows 5.5-stage Vacuum Suction Cups ZP3P-JT, available in a range of diameters including 20mm, 25mm, 32mm, 40mm, and 50mm. This series is specifically engineered for automated film packaging applications within the food and medical industries, and is also ideally suited for handling various flexible materials prone to deformation. The 5.5-bellow (accordion) structure features embedded internal support ribs that effectively prevent the suction cup walls from sticking to one another; furthermore, the inherent cushioning stroke capability of this design automatically compensates for height discrepancies encountered when gripping bagged materials.
