Fabricating beautiful and smooth cavities onto glass workpieces
Glass cavity etching process:
Etching the glass workpiece without penetrating the bottom side of the workpiece so as to form cavities (cavity depth adjustable).
This process is often adopted for workpieces such as OLED cap glass, because with chemical etching, this process is capable of fabricating flawless and smooth cavities which are exquisitely transparent and able to transmit lights without distortion.
Features
