Tools at Low Cost All the tooling that is required for Photochemical Milling is created via CAD quickly with no time and cost consuming mechanical processes. These tools can be used for a long time to produce exactly the same part over and over. Rapid and Low Cost Design Changes Photochemical Milling allows practical experiments with the design at low costs. Changes to the design could be done at prototype or latter stages of the process. Half-Etched Lines Forming lines can be half-etched into the metal to allow components to be formed latter by hand. This minimizes costs and lead times. Complex Shapes with Ease Photochemical Milling allows creating the simplest washer to the most complex parts with the same ease, cost, and time required. Prototype to Full Production Photochemical Milling allows making any number of parts using the same tool every time. This allows the engineer or designer to develop their concept from prototype to full production quickly and easily. Burr Free and Stress Free Part Photochemical Milling produces burr free parts, thus eliminating the need for costly time-consuming de-burring. This process does not affect the properties of the metal with regard to hardness, grain structure, or ductility of the metal. Identification Marks Putting company logos, part numbers, contact information, or other identifying marks on parts are milled into the surface with ease at no extra cost to customers.
