Precision chemical etching for industrial applications

See the step-by-step detail and FAQ below. >Industrial users of chemical etching are usually solving a problem that machining or stamping handles badly: very thin material, intricate internal geometry, or a part whose shape makes a hard tool expensive. Photo etching is a subtractive, photochemical process, so it costs nothing in tooling and reaches detail that would be uneconomic to machine.

Where the process wins in industry is in screens, meshes and filters. A woven or etched mesh for a filter, a screen for a gas, a shim for a heat exchanger, a gasket for a pressure vessel, or a spacer for an instrument. These parts share a characteristic: they are thin, they are made in volume, and they are specified by the drawing rather than by a standard.

The critical parameters in this work are flatness, burr-free edges and repeatability. Flatness matters because an etched part that bows will not seal; burr-free edges matter because a burr in a screen or filter changes the flow behaviour; and repeatability matters because an assembly line has to work with the part it receives, not with a nominal drawing.

We work to ISO 9001 requirements, provide material certification with each batch, and can issue dimensional inspection reports and first-article inspection reports. For customers who need visual consistency, we can also supply a first-article sample for approval before the batch is released.

Because etching is done flat, formed parts are usually etched in the blank state and formed afterwards. If you are specifying a part, it is worth telling us the end form early, because it affects how the artwork is distributed across the blank.

Frequently asked questions

What is the difference between precision etching and general etching?

Precision etching implies tighter control of dimensional accuracy, edge quality and flatness, usually with documented inspection. General etching may meet a functional requirement without the same level of measurement or traceability. For an assembly line, the difference matters less than the repeatability of the batch.

Do you work to customer drawings or produce standard parts?

Almost always to your drawing, because a photo etched part is unique to its artwork. If you have a concept rather than a drawing we can help convert it into a manufacturable artwork and give feedback on what is achievable in your chosen material and thickness.

What industries do you supply precision etching to?

Industrial equipment and instrumentation, oil and gas filtration, automotive and rail, electronics and control panels, medical and laboratory equipment, and identification and signage. We also supply architectural and decorative work in the same process.
