ch technology
The technology of removing metal from the metal surface by means of erosion on the metal surface. This method is used on the surface of the metal
All kinds of patterns are called etching processing, and the mold industry is called etching processing, also called bitten flower processing or “corrosion processing”.

(1) electrolytic etching (electrolytic etching)
Using the mother mold as the conductive cathode, the electrolyte is used as the medium to carry out etching etching to the processing part.
(2) chemical etching (chemical etching)
Using the drug resistant coating, the etching erosion is removed and the action is concentrated on the desired parts.
Photo etching technology (photo-etching process) formed a uniform layer of optically active drug resistant coating on the metal surface.
(photo resist), and through the original film negative, exposure to ultraviolet light, after the imaging processing, to form the desired drug resistance.
The coating layer of the coating is then dissolved by the chemical or electrochemical erosion of the exposed part with the acid or lye of the etching bath.
The processing technology of the genus.
(3) characteristics of etch technology
1, do not need electrodes, master and other tools, so there is no need to maintain such tools.
2. From planning to production, the time needed is short, which can be used for short-term processing.
3, the physical and mechanical properties of materials are not affected by processing.
4, processing is not restricted by shape, area and weight.
5. The processing is not limited by the hardness and brittleness.
6. It is capable of processing all metals (iron, stainless steel, aluminum alloy, copper alloy, nickel alloy, titanium and alloy).
7. High precision machining.
8, complex, irregular and discontinuous design and processing can be applied.
9, large area, good processing efficiency, but small area, its efficiency is worse than machine processing.
10, the horizontal cutting is easy to get high precision, but the depth and vertical direction are not easy to get the same machining accuracy.
11, the composition of the processed products should be uniform, and it is not easy to process the heterogeneous materials.
