VACUUM CUP PROPERTIES
Type Selection Guide
Type Flat Cups
1 5 Bellow Cups
2 5 Bellow Cups
The flat suction cups provide accurancy in in load gripping and speeds up up the cycle process Flat cups are used only on
on
flat surfaces The 1 5 bellow cups cups combine the the advantages of the the flat suction cups cups (precision and positioning) with the freedom of belows (angle and and flexibility) They provide flexibility flexibility precision and and low low internal volume suitable for high-speed applications The suction cups with with 2 5 bellow are recommended for gripping products with with un-even surfaces (large deflection) The 2 5 bellow allow objects to be be gripped from an an angle (ball-joint effect) Material Properties

The holding force of the the the the the suction cups increases proportionally with the the the the the difference between the the the the the ambient pressure pressure and the the the the the pressure pressure inside the the the the the cup cup The holding force of a a a a a suction pad is calculated with the formula:
F =ΔpxA F = Holding force Δp = Difference between ambient pressure pressure and pressure pressure of the system A = Effective suction suction area area (the effecive area area of a a a a a a a suction suction pad under vacuum) www mouldpro com 173
This means the the the the the the the holding force is is proportional to the the the the the the the pressure pressure pressure difference difference and and the the the the the the the suction suction area The greater the the the the the the the difference difference between ambient pressure pressure pressure and and pressure pressure pressure in in the the the the the the the suction suction cup or or or the the the the the the the larger the the the the the the the effective suction area the the greater the the holding force The force can vary depending on
a a a a a a a a a change of the pressure difference and area parameters
