Customized silicone rubber suction cups as per your drawing

Custom silicone rubber suction cups need the lip and mounting features to be defined as one working component. The contact surface determines the necessary rim profile, while the holder or vacuum connection sets the geometry behind it. Altering one without considering the other can change how the cup sits under load.

Define the intended orientation and movement along with the available contact area. The selected silicone formulation should suit the workpiece surface and operating exposure. A custom outline does not establish a carrying capacity by itself, and a larger contact diameter is not a substitute for evaluating the complete arrangement.

Check that the rim remains continuous against the actual surface without bridging a seam or texture. Verify that the mounting connection does not twist the cup or distort its lip. During service, inspect contact edges and attachment transitions for damage. Replacement parts should preserve the chosen configuration so a visually similar cup does not introduce a different contact profile or connection depth into the same system.
