Hannover Messe – 17 – 21 April\u00a0 2023 <\/strong><\/p>\n

The micrometal Group exhibited at the Hannover Show April 17-21. The company demonstrated to visitors that it offers the next generation photo-chemical etching (PCE) process which is orders of magnitude more precise and repeatable than any other PCE process on the market.<\/p>\n

Jochen Kern, Head of Marketing at micrometal says, \u201cWe were excited to be at the Hannover Show again this year, and it is always useful being able to show visitors the power of our next-generation PCE process. Manufacturers in general are interested in PCE as it is able to produce burr and stress-free metal parts with great precision. However, over time, micrometal has evolved the process to exceed the precision and repeatability of traditional PCE suppliers, and this is opening up possibilities in product design and manufacture hitherto impossible.\u201d<\/p>\n

Design engineers are increasingly turning to PCE as they are under pressure to create smaller and increasingly complex precision metal components. As with any process selection, designers need to be aware of the specific attributes of the chosen manufacturing technology when looking at design attributes and parameters. The versatility of PCE and its unique advantages as a precision sheet metal machining technology makes it an engine for design innovation, and can truly be used to manufacture parts that would be deemed impossible if using alternative metalworking technologies.<\/p>\n

micrometal\u2019s next generation PCE process builds upon the precision of the legacy PCE process, and uses a unique and patented wet paint etching system, the coating being 2 \u2013 8 microns thick as opposed to traditional dry PCE coating which are 10 \u2013 50 microns thick. Liquid photo-resist is more suitable for high precision mass production in continuous processes, results in higher reproduction accuracy, and allows very small feature sizes or 25 microns to be produced, a minimum hole diameter 80% of the material thickness, and single digit micron tolerances repeatably.<\/p>\n

micrometal also uses high-resolution glass photomask tools printed at 100,00 dpi, providing superior reproduction and resolution than film photo-tooling used in conventional chemical etching processes.<\/p>\n

High-resolution glass photomask tools are inexpensive to make, and very easy to adapt. In addition, the cost of glass tooling does not increase significantly with part complexity, which cannot of course be said for steel tools. In addition, glass tooling does not wear out, and also it does not impart distortion and stress onto the metal being processed, and produces parts that are completely flat. In many instances, via PCE a part will have been manufactured in volume before the tool-maker has even pushed the button on the fabrication of a steel tool which then may have a lead time of months before completion.<\/p>\n

Kern continues, \u201cThis combination of liquid etch and glass tooling provides extremely precise control of the etching process, enabling configurations, features and tolerances that cannot be achieved by other methods such as stamping, laser machining, or traditional PCE. 3-dimensional features can actually be etched into the thickness of the material itself, and dimensional tolerances as low as +\/-0.005mm can be achieved. Traditional PCE uses relatively thick dry film resist which compromises ultimate part precision and the tolerances that are available, and it is only able to achieve a smallest feature size of 100 microns, and the smallest hole diameter is a factor of 1-2 when compared to material thickness.<\/p>\n

Photo chemical etching is perfect for applications that require metal components with ultra-high precision on thin material. It can produce unique physical features, unique surface textures, identification features and is characterised by extreme consistency part-to-part and competitive cost.<\/p>\n
