Custom made pneumatic rubber suction cups for industrial use

Pneumatic rubber suction cups provide the workpiece contact in a vacuum handling arrangement. The custom molded shape needs to suit the pickup surface and the connection to the pneumatic system. The cup is one element in a cycle that includes approach, vacuum establishment, movement, and release.

Check the surface the lip will meet and the clearance available around it. The cup must contact the intended area without bridging a seam or being obstructed by a nearby feature. The selected compound should suit the workpiece and any temperature or contamination at the pickup point.

Evaluate the timing and movement with the complete system. Vacuum needs to reach the required condition before the workpiece is moved, and release must occur in the intended position. Load, orientation, acceleration, and leakage affect the arrangement, so cup dimensions alone do not establish capacity. Inspect the lip and attachment regularly for damage or looseness. If the workpiece changes, reassess the contact and operating cycle rather than assuming that a cup suited to the previous surface will perform identically.
