Ceramic Suction Cups and Precision Ceramic Rods
Controlled-porosity ceramic vacuum chucks for uniform, damage-reducing wafer and thin-substrate holding.

01Product Overview
Porous ceramic vacuum chucks hold thin wafers, foils and films across an even field of micropores instead of discrete vacuum grooves, reducing local stress and back-side damage.
We supply chucks with controlled pore size and porosity and precision-ground, flat working faces tailored to substrate size and vacuum level.
02Key Features

Frequently Asked Questions
Can pore size be tuned to my substrate?
Yes — pore size and porosity are selected to the workpiece and vacuum level, and the working face is precision ground.
Do you supply larger photovoltaic panels?
Chucks are supplied in diameters from 25 to 450 mm; larger formats are assessed against our partners' capability.
Is this a finished assembly?
We supply the ceramic chuck component. Vacuum port integration and mounting features can be added to your drawing.
