The etching steel process has been widely used in the industry today. With the continuous advancement of technology and scientific research, people's daily life level and aesthetic concept have been continuously improved, including the electronics industry, the production of metal signs, the production of metal mold decorative lines, Production of metal decorations, production of precision hardware accessories, etc. More and more products are being produced using etching steel processes.
(1) Application in the electronics industry
The application of etching steel technology in the industry has become increasingly mature and extensive. The main embodiment is the application in the electronic information industry, mainly embodied in electronic digital products, such as mobile phones, digital cameras, tablet computers and other hardware accessories, because the requirements are relatively high, the traditional stamping process can not meet people's requirements. The defects manifested in the metal etching are just solved by the etching steel process. The etching steel process not only solves the dilemma of the traditional process, but also has a leaps and bounds in precision.
(2) Application in decorative manufacturing
1. Production of metal signs
In the past, the production of some signs was mainly made of non-metallic materials such as wood boards, slate or cement boards, and characters and patterns were printed on the boards. With the development of technology and the increase of plastic products, stainless steel signs have gradually become popular. With the development of metal manufacturing, more and more units use metal plates to make signs. The metal plate sign shows the text or pattern by etching, which can be made into a convex shape or a concave shape. It has a certain three-dimensional feeling, and has a metallic luster setting, which is magnificent and solemn. The surface of the metal sign can also be colored to further enhance the decorative effect.
Most of the metal signage is made by etching the text using chemical etching. The etched portion should not be too bright, and should be contrasted with the metal substrate sheet to have a certain metallic texture and artistic sense.
2. Production of metal mold decorative lines
With the vigorous development of various industries, the application of plastic products is more and more extensive, and the types are also increasing. Decorative patterns are produced on the molds for producing plastics, and the corresponding pattern patterns can be obtained on the surface of the plastic products, thereby increasing the variety of colors and ornamentals of the products. For example, the surface of the car dashboard and the rear cover of the motorcycle are made of decorative patterns, which are not only beautiful and beautiful, but also can make the plastic surface extinction. Faux leather belts, purses, suitcases and leather shoes made of imitation leather can almost achieve the degree of realism and simulation effect, so that their value doubles.
In addition to computer or hand-painting, most of the decorative pattern is made of plastic samples or decorative patterns on artificial leather. Plastic samples should be selected with a clear, even and flat surface. Spray a layer of black self-drying paint, dry it, apply it with white powder of 200 mesh or more, fill in the grain, and gently wipe off the white powder on the protruding surface. Make it black, until the layout is clear, black and white, and the base map is finished. If the artificial leather decorative pattern is selected, the artificial leather is first flattened on the wooden board, and the base pattern is obtained according to the above. The pattern is then etched onto the mold by photographic etching or screen printing etching.
Similarly, in order to improve the decorative effect of the surface of the injection molded article and cover the surface defects of the mold cavity, it is necessary to perform pattern processing on the surface of the mold cavity. The processing process is to first make a protective film with a pattern on the surface of the cavity, and then complete the process of corrosion forming in the etching solution. The protective film (mask) is usually produced by a photosensitive method and a transfer method, and the photosensitive method is photographing, developing and then etching. The transfer method is to transfer the pattern to the inner surface of the desired cavity by screen printing, and then obtain the etched pattern by baking and etching.
3. Production of metal plate pattern decoration
The decorative metal types are mainly steel, stainless steel, copper and copper alloys, aluminum and aluminum alloys. The varieties are doors and windows with decorative patterns, furniture, ceilings, closet doors and decorative wall panels. At present, most of the domestically produced pattern decorative plates are made of etching steel, which is relatively expensive, and is also made of other thin metal shims such as copper, aluminum and other alloys. The price is also relatively expensive, and high-quality ordinary steel plates can also be used to produce high quality. The pattern is decorated with a decorative sheet, but it needs to be plated or sprayed to receive a good decorative effect.
