The Julid Process of photochemical machining (often abbreviated as PCM, and sometimes referred to as photo chemical milling or photo chemical etching) is a technique for manufacturing high-precision flat metal parts. By chemically etching away the unwanted materials, a photographically prepared mask (a Phototool) is used to protect the metal that is to remain after the etching process.   

 

1.You provide us with your CAD drawing (in .dwg, .dxf format) or sample,Our engineers will  work with them, then produce an exacting AutoCAD-generated phototool. This phototool is a faithful replica of your part, meeting all of your specifications.

2.We thoroughly clean the metal you have carefully chosen for your part and its specific use. The major materials we use are stainless steel, copper, brass and molybdenum.

3.We apply a photoresist coating to make the metal surface sensitive to light.

4.We contact expose the phototool to the sensitized metal surface with a UV light source, then treat the metal in a developing solution to create a hardened image of the desired part on the metal surface.

5.We process the metal surface with an etchant to give you the desired design.

6.We inspect the part, remove all photoresist, clean the part, inspect it again, package to prevent damage and ship.

7.In order to protect our enviroment ,we treat all waste water and recycle the spent etchant solution.
