Precision Glass
Using proprietary glass forming processes,
GBC produces precision glass tubing and
rods. These glass components are used
in miniature fuse bodies, lenses for photo
transistors, glass-to-metal seals used
in IC packages, Erasable/Programmable
Read Only Memory (EPROM) and Read Only
Memory (ROM) glass lenses...and many others.
GBC employs two distinct processing techniques.
Each has the ability to manufacture small
or large quantities of glass tubing and
rod to precise tolerances.
The "Direct Draw" process
enables GBC to draw in a variety of colors
and compositions to meet customer demands.
The "Re-Draw" process
allows GBC to provide custom drawn tubing
from readily available compositions.
