Photochemical Milling

At Faspro Technologies, we use Photochemical milling to process sheet metal components. We use a photoresist that surrounds the metal part and then apply an etchant that corrosively removes material where it contacts the part. Due to the low cost and the quick turnaround it provides, Faspro uses photochemical milling as a key part of our prototype development process.

Faspro stocks a variety of material in rolls

Low Cost Tooling

All the tooling that is required for Photochemical Milling is created via CAD with low-cost and no time-consuming mechanical processes. Any design changes can be implemented within hours. The tools created are long-lasting and precise, producing exactly the same part within your specifications.

Half Etched Lines

Half Etching lines into the metal allows component parts to be formed by hand, lowering costs and increasing efficiency.

Complex Shapes Produced Easily

Photochemical Milling allows all parts, from the simplest washer to the most complex connector, to be created with the same cost, ease and turnaround time.

Burr Free, Stress-Free Parts

Photochemical Milling produces burr free parts without affecting the inherent properties of the metal with regards to hardness, grain, structure or ductility. This removes the need for expensive deburring processes.

Identification Marks

Photochemical Milling allows any needed identification markings.

Prototype to Full Production

Because the same tool is used for making all components, engineers can develop their design from prototype to full production, quickly and easily.
