Brass Photo Etching

Here at Qualitetch we offer a quality service for etching Aluminium. The process of chemical etching with Aluminium is a specialist process and we have many years of experience etching this metal.

This is due to the fact that aluminium can be difficult to etch correctly if you do not have the correct process controls in place, which can lead to poor edges and a rough finished profile. Qualitetch have developed a process with our chemistry engineers to ensure that only the best quality etchant is used in our process to give the best possible results to your metal components.

The reason this metal can be difficult to etch is that aluminium is exothermic, meaning that it creates heat and gases on the surface of the metal as it is being chemically etched, which causes the aluminium to blow outwards and smut with carbon; roughening the surface.

The Photo Etching process is flexible, highly accurate and cost-effective at any volume.

The photo etching process is known by many names, including chemical etching, acid etching and photo chemical machining (PCM). Utilising flat sheet metal to manufacture high quality and accurate parts and components for a variety of businesses and industries, Qualitetch offers only the very best service possible.

As well as providing businesses with their components within a short timescale, the method of production allows for high levels of accuracy, minimal margins for error, and is also cost-effective in both high and low volume orders.

Nickel Silver is an extremely useful metal due to its high resistance to heat and corrosion

This makes Nickel Silver a popular choice when developing a variety of components particularly RFI, EMC & EMI screening cans and shields for PCB's . At Qualitetch, we are able to offer both Nickel or Nickel Silver for any applications you require.

Even the most intricate of designs are possible with our cost-efficient and eminently accurate Photo Chemical Etching process. The material when finished profile cutting via etching will be burr and stress-free, and retaining all of its essential properties.

Following the finalisation of your design, we first clean the raw material nickel silver sheet and then the coat the sheet with a UV sensitive photo-resist, before then printing your required profile directly onto the UV photo resist covered sheet. After this, the material is then passed through a sprayed chemical bath solution of ferric chloride, which is used as our etchant to cut your profile design. Our chemical etching process works equally well for both soft annealed, half hard or fully hard metals, which effectively, we then acid etch a thin track line to an exacting standard to ensure your components are manufactured to your drawing design.
