Precision etching line processing is a process method for processing metal parts through photochemical reaction and etching. The stainless steel etching process makes full use of the current advanced computer-aided design technology to make the graphics that need to be processed into film, and then copy the film graphics to the surface of the metal material through a photochemical reaction, and form a protected metal part graphic on the surface of the metal material. The etching method etches away unprotected metal materials to produce metal parts.

Compared with the traditional mechanical punching method, the etching process has the advantages of short production cycle (generally 3 days can produce the product) and convenient and quick modification of the size. The mechanical punching method must have high-precision punching equipment and mold processing equipment, and the development cycle takes 2 to 3 months. Due to the particularity of the etching method, the complexity of the parts has nothing to do with the difficulty of processing. Relatively speaking, the mechanical punching method tends to increase the difficulty of manufacturing when dealing with complex parts, and some even cannot be processed. The etching method only needs to design and produce film (photosensitive adhesive, etc.), and the development cost of new products is low; the metal parts manufactured by etching process have no burrs, do not change the magnetic properties of the material, and the flatness of the processed product is not changed at all.

Etching processing is suitable for the processing of thin metal materials with many varieties, large batches, and large planes, as well as the surface process decoration (semi-corrosive) of metal products. It is also suitable for single-piece and small-batch proofing. It is now used in a variety of integrated circuit lead frames and fluorescent display arrays, grids, encoder gratings, precision filters, microelectrodes, integrated circuit cover plates, mask plates, kinescope shadow masks and other products.

What are the characteristics of etching processing?

1. Products with complex shapes can also be etched without adding other costs

2. Low mold opening cost, etching process can be changed arbitrarily according to the requirements of the designer, and the design requirements are low, and the cost is low

3. The precision can reach +/-0.005mm accuracy, meeting the assembly requirements of different products

4. It can realize the half-cut of metal, increase the company LOGO, and realize branding

5. Almost all metals can be etched, and there are no restrictions on various pattern designs.

6. Both thick and thin materials can be processed to meet the requirements of different assembly components

7. Manufacture various metal parts that cannot be completed by mechanical processing

8. There are no burrs, pressure points, the product does not deform, does not change the material properties, and does not affect the product function.
