Tech-Etch photo etches polyester film to make flat parts for many applications. Typical photo etched applications include non-conductive washers, dielectrics, diaphragms, gaskets, washers, discs, spacers, seals, and caps, plus insulation layers and liners. Parts can be etched with intricate features in addition to a partial etch to form relieved shapes on the polyester film's surface.
- Photo etching or photo chemical milling Polyester offers low tooling cost, very fast turnaround and enables rapid design changes.
- Commonly made from polyester sheet up to .010" thick.
- Sheet can also be depth etched with grooves or channels.
- Polyester is a high-strength, hydrophobic, solvent-resistant, optically clear material.
- Clean burr-free edges.
- Prototype to production.
