Machine off rigid Geon produces low cost precision etching on glass *'Chemical machining" is the accurate term for the high precision etching on glass done by this new machine. Square-cornered, submicroscopic holes can be produced with small tolerances and close center-to-center distances. Or a precise pattern can be created in glass, whether it involves holes, cut-outs, or channels. Screens with mesh as fine as 560,000 holes per square inch have been produced. The machine is made of shapes, sheets and rods made of Geon rigid

vinyl. Geon is unaffected by t h e acids that do the etching job. I t provides the durability and impact strength needed for fabrication. And it is as easy to handle as any material used for manufacturing. Here's another example of the way Geon vinyl can open new markets or improve old applications.
