The detailed explanations of several important coloring techniques for contemporary stainless steel in Kunshan sheet metal processing and decorative art are presented. These techniques often yield unexpected results in the practical process.
Surface polishing is the technique of using machines or manual methods to grind the surface of stainless steel sheet metal to achieve a polished appearance. Surface polishing can result in various outcomes such as polishing, mirror finish, satin finish, and sandblasting. Depending on the difference in the appearance result, the tools and methods used also vary. The polishing tools include abrasive cloth, sandpaper, polishing wheels, polishing belts, grinding wheels, etc. During the polishing process, countless abrasive particles are equivalent to countless very hard blades, performing cutting operations on the surface of the stainless steel sheet metal to achieve a smooth finish.
Mirror finish treatment involves pre-polishing and fine polishing. Pre-polishing is a process where a hard or relatively hard polishing wheel is used to treat the polished surface of the stainless steel sheet metal processing. It can remove the coarse marks left on the polished surface. Fine polishing uses a soft material to further process the pre-polished surface, removing the marks left by pre-polishing and achieving a bright mirror finish.
The silk-textured finish is achieved through the process of using a polishing wheel installed on a polishing machine to process the appearance of stainless steel sheet metal, resulting in decorative silk-textured polishing and satin finish effects.
The sandblasting result is achieved by using a compressed air flow to spray sand or abrasive materials such as steel balls or glass balls onto the surface of the stainless steel sheet metal processing, resulting in a uniform and aesthetically pleasing, slightly rough texture.
Surface etching and etching paintings are decorative effects achieved through the corrosion of chemical acids. The detailed process is as follows: First, apply a layer of asphalt to the surface of the stainless steel sheet. Then, draw the planned patterns on the asphalt surface, exposing the part of the stainless steel sheet that needs to be corroded. Now the corrosion can be carried out. The corrosion can be done by immersing in the chemical acid solution or spraying the solution. Generally speaking, for small works, the immersion method is chosen. Chemical acids have extremely strong corrosiveness, and during the corrosion process, it is essential to be meticulous and take proper safety precautions.
The appearance inlay technique has a long history. It includes two types of techniques: inlaying stones and inlaying gold. Regarding the description of the gold inlay technique, it is also known as gold and silver inlay. First, it draws patterns with dark lines on the surface of the stainless steel sheet, then inserts gold or silver wires or sheets (which are relatively soft stainless steel sheet materials) into these patterns. Finally, it polishes them to a smooth finish. The result is extremely delicate and magnificent.
The shaping of the appearance also originated from the ancient casting techniques. It involves using different-shaped hammers to perform forging on the surface of stainless steel sheet metal, thereby creating variously shaped point-like textures. These textures are layered one upon another, making it highly decorative.
