Chemical Milling 

Our Chemical Milling process is used to produce thin (up to 3mm thick) metal components in a variety of ferrous and non-ferrous metals. 
These metal components (which previously would have been manufactured by conventional machining or blanking operations) are produced using acids to dissolve away the unwanted material, leaving you with the exact shape and size of your finished components. 
The Chemical Milling (also know as photo fabrication) process also allows surface detail to be etched into one or both sides of the component at the time of manufacture. 

Advantages over conventional milling 

Low cost 
Fast production times (standard lead time 5 working days) 
Chemically Milled components are free from mechanical stress 
Burr free 
No burnt edges 
No processing residue (dross) 
Complex shapes can be produced 
Master tool is generated by computer graphics 
If you can draw it, we can make it! 

Why choose chemical milling? 

Anything is possible 

Chemical Milling is the ideal process to produce complex shapes, because there are no additional processing costs for even the most complex of profiles or complicated hole arrays. 
Tooling consists of a set of precision photographic negatives, produced on the industries’ best design and drafting programs. Once drawn and QA approved, they are stored on our dedicated server and available for printing at any time. As well as being very efficient, you can modify your component at any time, without expensive tooling modification charges. Unlike hard tooling methods, the existing tooling does not have to be decommissioned in order to make modifications. Your production schedule is not at risk in any way whilst your modifications are implemented. 

Part Marking and Low Cost Forming options 

The Chemical Milling process allows surface detail to be etched into one or both sides of the component at the time of manufacture. Your company logo, part numbers, address or even a picture can be permanently etched at your desired location. The same technique is utilised to accurately inscribe lines on the surface to allow parts to be hand folded without the need for form tooling, a process which is widely used to form EMC/RFI screening cans. 

Main advantages include: 

Rapid manufacturing process (standard lead time 5 working days) 
Complex profiles, burr and stress free components 
Ideal for prototype and production volumes 
Design changes and modifications rapidly and economically produced 
Half etched fold lines for part marking and cost effective forming
