FlexiGrip

minigrip schema small

Versatile

 

Foams adjust to smooth and rough surfaces easily 

Level compensators allow the Mini-Gripper to adjust for uneven layer heights without changing the mount 

Ability to pick a variety of products without adjustment 

Unlike larger grippers, with fixed hole locations, arrayed Mini-Gripper(s) may be moved to obtain a variety of pitches 

Provides a new way to obtain faster cycle times!

 

 

Compact

 

Easily adaptable to current tight clearance applications comparable to vacuum cups 

No need for over sizing for small applications. MGs do the trick! 

The vacuum source can be installed directly to or close to the Mini-Gripper to maximize its capability and efficiency (If using the manifold (VM) vacuum source, it must be installed close to the gripper(s) 

Much smaller sizes compared to FlexiGrip grippers

 

 

Easy to install

 

Initial installation or changing a MG out for another is a snap! 

One 10mm compressed air fitting makes for quick push-lock connection to airline (airline - 10mm O.D.) 

Retrofit existing cups or existing pump system
