Photo-chemical etching (PCE) is a versatile and sophisticated metal machining technology, with an ability to mass manufacture complex and feature-rich metal parts and components. . Here Dr Angel Lopez, Director of Business Development at micrometal GmbH discusses what 10 considerations design engineers need to bear in mind when working with PCE.

Photo-chemical etching is renowned today as a metal processing technology that produces stress free, flat components by selective etching through a photo-resist mask. It is especially well suited to the manufacture of precision parts such as grids, meshes and precision filters.

The unique characteristics of PCE overcome many of the issues associated with more traditional metal cutting technologies, and as such — in some instances — when looking for a cost-effective solution for the manufacture of precise metal parts, it is the only viable choice.

micrometal GmbH has announced the availability of a new White Paper entitled “Unlocking the True Potential of Precision Metal Fabrication” which analyses the photo-chemical etching (PCE) process. The White Paper is presented in an accessible and interactive way, with a video link to an animated demonstration of how the technology works.

micrometal GmbH is pleased to be able to provide Parylene protective coatings to the precision metal parts and components made using its photo-chemical etching (PCE) process. Parylene is the ultimate protective coating, and is used for customers that require protection of equipment, components, and surfaces in a range of end-use applications.

Very often both sides of plate heat exchangers contain extremely complex features which are sometimes beyond the ability of stamping and machining, but are easily achieved using PCE. In addition, PCE is able to produce features on both sides of the plate simultaneously saving significant amounts of time.
