Acid etching, also known as photo etching, chemical etching or chemical milling, is a sheet metalworking technology which uses acid etchants to machine complex, highly accurate precision metal components.
At ZYH etch, we use acid etching to replace machining processes such as stamping,laser and water jet cutting, and we provide a fast, economical alternative for machining everything from nearly any thin gauge metal to 2mm thick precision, tight tolerance parts.
1. Reduce mold cost and development cost. It can be arbitrarily changed according to the designer's design requirements to achieve half-etching of the metal surface, increase the company's LOGO, achieve brand transformation, and use it against theft.
2. The sample development cost is low, the precision is extremely high, the precision can reach +/-0.02mm, the thinner the material, the higher the precision control.
3. The development cycle is short and the sample delivery time is fast.
4. Products with complex shapes can also be etched without additional cost. It can also cope with miniaturization and diversification. ZYH has the opportunity to realize customized services for different customers at home and abroad, instead of only doing large-scale products.
5. No burr, no pressure point, solve many problems in stamping, laser cutting and other processes. At the same time, the precision can meet the product requirements, even better than the above-mentioned processes, and there is no substitute.
6. The manufacture of various metal parts that cannot be completed by mechanical processing. Stamping and laser processing cannot complete the processing of fine and ultra-thin materials, while the ZYH metal etching process is easier to handle.
The photo etching process works by "printing" the component design onto a photosensitive coating on the metal surface. The unprinted areas of the photosensitive coating are removed, exposing the metal, which is then etched away by the chemical liquid.
Almost any metal can be etched.
Other specialty metals, including molybdenum and polyimide metallized films We also use customer supplied materials.
