Etching Is a Technology That Uses Chemical Reaction or Physical Impact to Remove Part of Materials.

Etching is a technology that uses chemical reaction or physical impact to remove part of materials. etching technology can be divided into wet etching and dry etching.
The earliest can be used to manufacture copper plate, zinc plate and other printing concave and convex plate, is also widely used in Weight Reduction instrument panel, nameplate and traditional processing method is difficult to process thin workpiece processing; After continuous improvement and development of process equipment, it can also be used for precision etching products of electronic wafer parts in aviation, machinery, chemical industry, especially in the semiconductor process, etching is an indispensable technology.

Generally referred to as etching, also known as photochemical etching, it refers to the removal of the protective film in the etched area through exposure platemaking and development, and contact with chemical solution during etching to achieve the role of dissolution corrosion, resulting in the formation of concave and convex or hollow molding.

Exposure method: engineering according to the figure out the size of the material preparation - material cleaning - drying → film or coating → drying → exposure → development → drying - etching → film removal →OK 
Screen printing method: opening → cleaning plate (stainless steel and other metal materials)→ screen printing → etching → film removal →OK
Etching excellent version: The use of inkjet printing technology will be anticorrosive ink printed on the surface of the material, and then after curing (generally light curing, but also useful thermal curing) can obtain the anticorrosive layer and then can carry out the next chemical corrosion or electrical corrosion.

Stamping: Workpiece Formed Through a Stamping Die by Means of Press Pressure

Stamping parts rely on press and die to impose external force on plate, strip, pipe and profile, so as to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece (stamping parts) forming processing method. Stamping and forging belong to plastic processing (or pressure processing), collectively known as forging. The blanks for stamping are mainly hot and cold rolled steel plates and strips.

Stamping Parts Characteristic Application

Stamping parts are the production technology of parts with a certain shape, size and performance by means of the power of conventional or special stamping equipment, so that the plate is directly subjected to the deformation force and deformation in the mold. Sheet material, die and equipment are the three elements of stamping processing. Stamping process is a cold deformation process of metal. Therefore, it is called cold stamping or sheet stamping, referred to as stamping. It is one of the main methods of metal plastic processing (or pressure processing), also belongs to the material forming engineering technology.
