Our company is a manufacure that produce etching products including glass accessories, metal etching mesh,metal bookmark, metal model plate, metal nameplate and filter etc. by adoptting  photo chemical etching technology . Photochemical etching is simply a high-quality, fast-turnaround and low-cost alternative for machining flat metal parts. it offer you the precision and accuracy unavailable in other type of milling processes. The conventional process meant stamping which required a matched punch and die. It caused  stress, deformation and burrs. The photo etching has not only eliminated these problems, but enable manufacturers to process parts accurately and much faster than before. It doesn't change the metal compositon such as heat or mechanical stress on finished parts.
