Benefits of Chemical Etching Process
Accurate and Complex
Metal etching has the capability to make extremely complex designs and accurate metal components. Since all the features are being machined at the same time the complexity can be endless.
Bur Free and Stress Free
Since the etching process is chemical machining instead of mechanical machining the components will be bur free, stress-free, and will maintain all its original metal properties.
Fast Prototyping and Quick Design Changes
Metal etching has a digital tooling process that allows etcher owners to make fast changes to component designs.
Endless Metal Options
There is a list of metals that Chemcut has built chemical etchers for on our Chemical Milling Page.
Common Line Parameters
Speed range: 14 – 140 inches / minute
Max temperature: 130 °F
Processes will vary depending on metal, etchant, and desired properties of product.
Why should a company add chemical etching to its capabilities?
No stress hardening
Burr free – stamping produces parts with sharp edges, requiring removal for safe handling
Unlimited complexity. Typically, chem milling companies charge for the first hole
Quick turn around on redesigns – giving the ability to produce multiple prototype designs with minimal down-time
Quick and cheap prototyping because the artwork is inexpensive
No expensive hard tooling like stamping
Etched parts are NOT compromised by contamination. Many parts are used in the medical field
Nearly any metal can be etched in a Chemcut machine
Acid Etching metal on a Chemcut machine can have a tolerance of 10% of the material thickness; even better with artwork compensation prior to resist exposure
Tolerance of 1 mil and lower is achieved by many of our customers.
