metal mesh
meshes with features other processes would find difficult or impossible to make can be made by the chemical etching process. During the etching process we dissolve any unwanted material allowing us to create intricate features in the form of very fine webs and very small holes.
For the width of the webs in a screen, the general rule in design is webs must be at least 2/3rd the thickness of material. For instance, on a screen etched out of .010 thick material the webs on the screen must be at least .006 wide.
Our process can also make screens that require small holes. The openings on the screen must be at least 20% larger than the material thickness. Therefore on a .010 thick screen the holes must be at least .012 in diameter.
Reel-to-Reel Chemical Etching can creates highly-repeatable unstampable, burr-free components with complex features for intricate metal designs and shapes on a continuous metal strip made from wide variety of ferrous and nonferrous materials.
This process can hold very close tolerances, and extremely high level of repeatability, and true position from metal part to metal part. The degree of precision and consistency achievable offers a continuous chemically etched metal strip and a mass production advantage alternative to the standard panel or sheet etching process.
