Modern hardware mainly refers to gold, silver, copper, iron and tin, and refers to metal in general. Hardware industry plays a vital role in the economy, hardware products industry has become an indispensable industrial link in industrial manufacturing. Manufacturing industry is the third major category of industries in China, in which the manufacturing industry of metal products and general equipment manufacturing in general parts and related products called "small hardware", "small hardware" responsibility is to provide parts and production tools to manufacturing enterprises, hardware Etching process is mainly for metal products and general equipment manufacturing in the general parts, through the means of etching process to the product processing production, that is, photochemical etching, means through the plate exposure, after the development, to be etched area of the protective film removal, in the etching of the metal contact chemical solution, the use of two positive graphics through the chemical flooding from both sides of the grinding to achieve the effect of dissolution corrosion, the formation of concave and convex or hollow The effect of forming a shape. Chemical etching is very specific and refers exclusively to controlled etching, a controlled processing of metal by chemical methods.

Hardware etching processProduct etching characteristics：

一、Low mold opening cost, low cost.

二、Able to realize metal semi-etching and add company logo.

三、Material thickness: 0.03mm,0.05mm,0.08mm,0.1mm etc.

四、Very high precision, up to +/-0.0075mm.

五、Complex shape products can also be etched at no additional cost.

六、No burr, no deformation of the product, no change of material properties.

七、Used for precision parts for automobiles, electronics, electrical appliances, hardware, etc.

八、Almost all metals can be etched, such as rare metals and molybdenum.

九、Manufacture of metal parts that cannot be completed by various types of machining.
