Confirm the air permeability to the workpiece.
Although it depends on the operating environment, the pad may be wearing quickly. Consider using a wear resistant material (urethane rubber).
Unsteady adsorption during the transfer can be considered, caused by the size of the workpiece, position of the center of gravity and etc.
When the black pad is used, black adsorption marks (pad wear marks) may remain on the workpiece.
The pads may not adsorb the workpiece depending on the unevenness.
<When there is unevenness in the workpiece>
1. Consider using a sponge pad.
2. Consider reducing the pad diameter.
