1. What is Etching Proceeding?
Simply speaking, Etching Process, also called Photochemical Etching or simply etching, is the technology extension of hardware stamping which need opening stamping die, but it is not suitable for the precious part due to its rough craft, big tolerance, and low precision, thus photochemical etching well meet the request for high precision in industrial production. Photochemical etching adopts the reaction of a chemical solution to etch the part is no need and keeps the final one we request. Great nameplates can well offer design and etching solution for metal business cards, metal plates, metal labels, meta tags, and other relevant metal items.

2. What is the general proceeding of Photochemical Etching?
Design→film making→raw material cleaning→anticorrosive oil printing and backing→exposure→developing→etching→cleaning and backing.

3. What is the connecting point during Photochemical Etching?
The connecting point is needed between two parts cut out in Photochemical Etching, its width is subject to the thickness of the material. Always the width is below 0.5 mm.
For easy disassembling of items from the big steel plate, half-etching noting for the point when the design is necessary.

4. What is the technical point of Photochemical Etching?
Photochemical Etching is a precious technology including spot color printing, exposure, developing and etching. It could reach a highly clear logo and text after etching although the logo and lines in design are tiny. This machining is widely used in the hardware finish process.

5.Photo Chemical Machining Process
Photochemical machining (PCM) plays a valuable role worldwide in the production of precious parts and decorative items, mainly metal business cards and labels.
PCM delivers low-cost tooling, low-cost modifications, prototype to production compatibility, metal properties unaffected, burr-free components, identification marks at no extra cost.
General progress: metal preparation, photoresist coating, photoresist processing, etching, stripping, and inspection.
Photochemical machining can produce components for multiple industries including aerospace, defense, medical, decorative, and mechanical.

6.The benefits of Photo Chemical Machining (PCM):
1.Low-cost tooling
All the tooling is created via CAD in a relatively short time with no long-winded mechanical processed involved. In the unlikely event of the tooling “wearing out,” replacement costs are minimal.
2.Low-cost modifications
The PCM process allows the designer to carry out practical experiments at a minimum cost. Short runs are possible ensuring that cost-effective improvements are easy to implement.
3.Prototype to production
PCM can be used to make one or a million parts, with the same tooling used every time. This allows the engineer or designer to develop their concept from prototype to pilot to full production quickly and easily.
4.Metal properties unaffected
PCM carries the unique advantages of leaving the internal structure of the metal unchanged. Neither does it affect the properties of the metal about hardness, grain structure, or ductility of the metal.
Some processes leave finished parts with a burr which is detrimental to the functioning of the parts. The PCM process produces burr-free components, thus removing the need for costly time-consuming de-burring.
6.Identification marks
Company logos, custom metal signs, part numbers or other identifying marks can easily be etched into the surface during manufacture at no extra cost.
