SEALING GLASS BEADS

Glass is an ideal material for hermetically sealed packages because of its high dielectric rating, attachment properties to metal surfaces, and mechanical stability over a wide range of operating temperatures. These features provide high electrical insulation, hermetic sealing of glass to metal, and high resistance to cracking as a result of thermal stress.

Accu-Glass LLC produces custom glass beads used to produce glass-to-metal feedthroughs and hermetically sealed connectors within the electronics industry.

The proprietary Accu-Glass tubing and rod forming processes are capable of melting various glass compositions suitable for sealing glass to metals that include Kovar, stainless steel, tungsten and titanium. The Accu-Glass precision glass forming processes provide the flexibility to produce low-volume prototypes or high-volume/low-cost production quantities.

Unique to Accu-Glass is the capability of producing multiple geometric shapes that include round, square, rectangular and oval cross-section configurations on either the OD or ID. Single and multiple bore configurations are also available. Custom tooling is done in-house to reduce cycle time and costs.

Diamond saw and score-snap cutting technologies are used to achieve desired tolerance of ±0.003” & ±0.009”, respectively.
