Etching technique of embossing roller.Plastic welding machine

　　I. electrolytic etching

　　Using the mother mold as the conductive cathode and the electrolyte as the medium, the etching erosion removal method is carried out in the machining part.

　　Ii. chemical etching

　　The method of removing the etching erosion by using a drug-resistant coating and concentrating the action on the desired part. The photo-etching process forms a fully and uniformly layered photoresist film on the surface of the metal; however, through the original negative, ultraviolet exposure, etc., is applied to image processing to form the desired shape of the drug-resistant coating. A process in which acid or lye from an etching bath is used to produce chemical or electrochemical erosion on the exposed part to dissolve the metal.

　　3. Characteristics of etching technology

　　1, do not need electrodes, master and other tools, so there is no need to maintain these tools.

　　2, from planning to production time is short, can be used for short-term processing.

　　3, the physical and mechanical properties of the material are not affected by processing.

　　4, processing is not limited by shape, area, weight.

　　5, processing is not limited by hardness and brittleness.

　　6, can process all metals (iron, stainless steel, aluminum alloy, copper alloy, nickel alloy, titanium, alloy).

　　7, can be processed with high precision.
