Sandblasted Chemical Etching Stainless Steel Smooth Surface No Embossment

Photo etching is used extensively in manufacturing custom meshes, filters and sieves as unlike conventional machining technologies the process offers unlimited complexity – you only pay for the first hole.

Manufactured in a single piece, photo etched meshes are slimmer, cleaner and have greater integrity, making them more robust during handling. Where punch-perforated sheets are prone to distortion, photo etched mesh is burr and stress-free, with zero material degradation.

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.

Benefits of photo etching:

1.  Very low set-up cost

2.  Design flexibility -- Photo etching allows much flexibility on product design no matter it is product outer shape or the hole patterns, there is even no cost for complex designs.

3.  Stress and burr free, smooth surface -- the material temper will not be affected during this process and it can guarantee a very smooth surface

4.  Easy to coordinate with other manufacturing processes such as PVD plating, stamping, brushing, polishing and so on

5.  Many material options -- stainless steel, copper, brass, aluminum, titanium, metal alloy at the thickness from 0.02mm to 1.2mm are all available.

6.  Fast lead time-- prototype to mass production can be finished within days.

Material:

SUS302, 304, 304L, 316, 316L stainless steel plate,Copper 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.
