Customer in New Zealand ordered etching zinc plates

In November, Hot Sales, 180 pcs etching zinc plates are packed for delivering to our customer in New Zealand. High quality zinc etching plates with good packaging.

The difference between etching technology and stamping processing is that it does not cause burrs on the edge of the component. It will not produce waste residue caused by laser cutting.

Eclipse can change the shape of the material, but it does not change the nature of the material. The laser cutting is different, and it will generate a considerable width -influencing area on the edge of the part. Purchase can also affect the nature of the material. For example, the edge of the blade of the burning equipment is thinner than other knives. Although the stamping can be used to process components of different thickness, it requires a high -tonnage pressure squeeze metal to form a thinner area. This will make these areas of metal harder, and a so -called processing hardening effect appears. Therefore, the parts processed by this method will generate different traits in different thickness areas. In contrast, etching can process different thickness components without affecting the hardness of the material itself.

    Another advantage of etching is that it is not affected by the hardness of the component material. The etching method has nothing to do with the softness and hardness of the material, while the stamping law is closely related to it. This limits the application effect of stamping technology for the application of pre -jitter. In most cases, the materials must be treated with heat treatment, which increases the variability of mechanical processing.

First of all, the etching requires a metal plate that is cleaned and covered with sensor coating. In order to erode the required component shape, the manufacturer first expresses the component drawing on the film (Filin) through the computer drawing. -Stripples for etching), if you need to etch on both sides, a pair of films are required, which are attached to the two sides of the metal plate.

After the film is placed, the material is exposed, and the light is only shown in the coating below the film light transmittance area. It is hardened by the light coating to facilitate the unable to dissolve the hardening coating later. After the development, spray the etching to the surface of the material, or immerse the material in it. The etching agent will dissolve the material other than the hardening protective layer, and the rest of the part is the required component shape.

Etching is to use the appropriate chemical solution to remove the part of the non -light resistance (sensor) in the material to achieve a certain carving depth.
