Machining a Wide Range of Sizes
GMI is capable of machining and fabricating graphite and carbon-graphite parts of practically any size from 1/16" in diameter to 24" x 48" x 120", which is the largest graphite manufactured today.

Fabrication of Larger Parts
At GMI, large vent tubes, chimneys, susceptors and retorts are being fabricated from smaller parts. This unique staved design eliminates the need for large diameter feeder stock which often has long lead times.

Graphite heating elements Heating elements measure just a few inches long.

Large diameter susceptors for induction furnaces are produced from solid graphite. Precision machined wedges can be assembled to create vent tubes up to 110" in diameter by 72" long.
