Chemical Etching - Design Guidelines

Etching – Design Guidelines

The chemical milling process is highly versatile when working with thin sheet metal. With nearly 50 years experience, we can offer chemical etching services including:

Etching – Design Guidelines Benefits

  • High accuracy
  • With forming capabilities
  • Of virtually any metal, from 10um to 1.5mm

From our experience, we have put together the following information to help you with your component design:

etching Metal thickness

Metal thickness

Metal thickness suitable for etching foils a few microns thick up to 2mm thick sheet (0.010 to 1.5mm). Thicker metals when etched will have a noticeable profiled edge “cusp” as detailed. Metals of any thickness can be surface etched.

etching design tolerances

Design tolerances

In certain instances, tolerances can be improved. Please contact our engineers for further information

formed component

Forming

We can form components using hard tooling or using jigs for a small quantity. We can “half-etch” to create fold lines, so that the component can be formed by hand. Our engineers will be pleased to advise you on specific components and costs.

Metal Flatness

This is determined by the standard provided by the steel mill. Tension levelled material is available when required. We operate within British Standard limits and offer flatness on metal of +/-10%.

Chemical Etching – Tabbing Guidelines

Our etching tabbing guidelines In order to further increase the precision of components and the ‘flawless look’ of decorative parts, Photofab ‘tab’ parts into sheets of metal. Tabs are slivers of metal, that serve to retain parts in sheet form. In other words, once completely etched, the components are not ‘loose’ parts, but instead are held into sheet form using …

Metals Suitable for Chemical Etching

The foundation of the component is the metal. Photofab take great care in the selection of the right metal for the component application. Wherever possible, Photofab use a special photo-etching grade, which is more uniform in thickness and flatter than normal stock. Our engineers and metallurgists will be pleased to advise on the grade of metal suitable for your application. …
