First, the metal forming: drawing process is a metal processing. In metal pressure processing. The external force is forced through the metal mold, metal cross-section is compressed, and obtain the required technology processing method called cross-section shape and dimensions of brushed metal. It changes shape. Size tool called drawing dies. The cable industry will 8mm copper rod copper wire drawing machine, by a group (5 to 8) descending drawing die, will pull into copper rod, copper wire, such as 3.5mm, 2.0mm and so on. Second, machining Finish: brushed cloth is reciprocated back and forth in the surface friction of the workpiece surface finish to improve a method of linearly textured surface. It can improve the surface quality, the hidden face minor scratches. In the conventional primary colors stainless, austenitic stainless steel is the most suitable coloring material can be obtained a satisfactory color appearance. Ferritic stainless steel due in the coloring solution increases the likelihood of corrosion resulting bright color than the former. The low chromium and carbon martensitic stainless steel, because of its corrosion resistance is even worse, you can only get dark color or black surfaces. According to reports, the austenitic stainless steel by using low-temperature surface oxidation coloring colored, exposed to the industrial atmosphere for six years, exposed to the marine atmosphere a year and a half, soaked in boiling water for 28 days, or heated to about 300 ℃ , it did not change its color gloss. In addition, it can withstand normal molding processing, drawing and bending and machining sclerosis. WiQ industrial design. China currently, colored stainless steel except for the outer walls of buildings and window frames decorated, it can also be used in many other areas. For example, a black stainless steel plate solar collector panel that selects the heat absorption rate up to 91% to 93%. In the arts and crafts field, stainless steel and color printing combined with polishing and etching may be cooperating outlets law process to produce three-dimensional relief murals never fade, hanging like. In addition, color stainless steel appliances, cookware, kitchen equipment, bathroom appliances, the favorite of consumers.
