Vacuum Pad, Suction Mark Prevention Type, VPMA, One-touch Fitting Type
Caution
Product Description
* The CAD data for this series is being revised. This will be available as soon as modifications are complete.
[Features]
· Ideal for LCD glass, coating processes, and transport of semiconductor manufacturing equipment.
· The flexible resin material adheres to work.
· Unlikely to make adhesion marks.
· Also, the characteristic separation in a workpiece at the time of vacuum breakage will increase.
· You can replace the resin pad without spanners and hexagon wrenches to detach the main body.
· Simple and compact structure.
· A wide range of pad sizes, pad materials, and holder shapes are available.
· Pad holders were added to applications with "copper-based metal not used" and "reduce ozone concentrations” requirements.
· Copper-based metal is not used for metal parts. HNBR is used for sealing rubber material.
