How Induction Getter Firing Works

A getter is a device containing powdered metal that strongly reacts to oxygen. In a variety of vacuum tubes including light bulbs, television sets, cathode ray tubes and vacuum-insulated tubes, the getter is heated using induction heating and the activated material oxidizes and absorbs oxygen and other impurities, which increases the tube’s life. Barium is often the element used as a getter.

Getter Firing Lighting Tubes

The process was completed within just 10 seconds, delivering the same result time after time, making it ideal for their high-volume manufacturing process

By flashing or firing the getter, the residual gases are removed from the inside of the display.

Getter Firing Light Bulbs

The 2.5 second firing cycle allows for the coil to be move around the part and away within the indexing time of the turnstile table.

About Induction Heating

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
