Photo etching, also known as chemical etching or metal etching, is a highly precise, tightly controlled corrosion process used to produce complex metal components with very fine detail.
When component integrity is critical, photo etching is often the only suitable metal machining technology as metal temper and magnetic properties are unaffected.
The etching process can be demonstrated in nine steps. Precision Micro has advanced these principles, investing in new technologies and developing proprietary methods which have set the standard for accuracy and repeatability.
The versatility of etching and its unique advantages as a precision sheet metal machining technology makes it an engine for design innovation. Our technical guidelines have been created to guide you through designing for the etching process, outlining achievable features and tolerances.
Photo etching can be applied to a vast spectrum of metals in a variety of thicknesses, grades, tempers and sheet sizes. Precision Micro stocks over 2,000 material types and in addition can supply specialist materials on request as well as work with customer materials on a case-by-case basis.
Precision Micro has been at the cutting edge of photo etching for over half a century. Find out why we are trusted to deliver by major international companies in over 30 countries worldwide.
Here you'll find answers to the questions we get asked the most about the chemical etching process and its design parameters.
