Glass/quartz/sapphire machining—-drilling,cutting,engraving,bonding,fabrication,induced etching

Glass, as well as quartz and sapphire parts are quite difficult for traditional processing methods, and today these material are more and more widely used in many industries and R&D. Walthy is experienced of designing and manufacturing the such works, we are able to drill min 0.1mm holes in 5mm thick glass, 2.5D structuring inside glass, and we cut glass with no chipping and high speed, so that we are always the important partner of our customers who dealing with glass products. We also have “laser induce etching” process for inside holes and micro channels etching, which is a revolutionary process to low the production cost a lot comparing with traditional methods


Cut/Drill/Engraving/Marking in glass,as well as induced etching

Glass thickness: 0.05~10mm

Min hole size: 0.05mm

Max cutting speed: 400mm/s @0.5mm thin glass

Min feature size(etching,depth,etc) : 10um

If you have difficulty to acquire such special works, please feel free to contact with us.

We share some jobs we have done in such materials as following:

glass-square-cuttingGlass chips cutting with high productivity (3*3*1mm), min chip size could be 0.1*0.1mm, and no chipping cutting edge under microscope

glass-cutting-qualityCutting quality with high magnification microscope: sidewall vew and top view

milling-and-drilling-in-glassGlass engraving(double sides etching and through square holes) + High density hole drilling in glass wafer, for MEMS application
