OEM Precision Etched Mesh , Acid Etching Metal Mesh Speaker Grille

Metal etching is also called chemical etching. It is a kind of high-precision, strictly controlled corrosion process, uses the principle that metal in tap water or salt water as the liquid of the main etching body produces anodic dissolution to etch metal. It is mainly used to produce high-accuracy complex metal elements that have high requirements for details.

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.

Material:

SUS302, 304, 304L, 316, 316L stainless steel plate, Low carbon steel plate, Aluminum alloy plate,Copper plate,brass plate.

Character:

precision double etching, smooth surface on both edges, no embossment, no convex-concave, no burnisher burr , no warping, no , any complicated pattern or geometric figure is available. Compared to perforated metal, it does not need polishing, and moreover, it’s very easy to change design and takes shorter producing time. It can produce what perforated metal machine can not produce.

Applications:

>Battery Plates

Rechargeable nickel metal hydride (NiMH) batteries are constructed using nickel as the positive node. The nickel electrodes, or cathodes, are grids or screens of varying configurations that are readily produced by photo etching. NiMH batteries are rapidly replacing NiCad because they do not contain toxic cadmium and offer better life cycle performance.

>Deposition Masks

Very fine features can be created in stainless, moly and other alloys to allow patterned depositions for a number of electronics applications.

>Filtration

Applications range from heavy gauge metal effluent filtration to extremely fine thin-gauge filters and diaphragms for liquids and gasses in a variety of alloys including steel, copper, aluminum, nickel and molybdenum.

Industrial, Commercial, and Scientific Applications for Perforated Metal:

Metal meshes can be chemically etched in a wide variety of alloys including steel, nickel, copper, brass, aluminum and more. Holes can be made in a variety of shapes and sizes at no additional cost in tooling.

Precision etched meshes, grids, filters and screens are used in many types of industrial, decorative and architectural applications. In many cases, chemical etching of metal meshes, grids, screens and filters provide better value and performance than woven or punched products.
