A small hardware products, as a fine arts and crafts, after layers of processes needed in order to practice a boutique. How to tell its intrinsic quality through the surface? Only close-up experience and knowledge of advanced production lines and professional, will be impressed by its excellent quality. The first metal production processes is mold making. CNC machining centers CNC lathes, computer 3D file import products through the preparation and processing procedures, the processing center to complete the processing. Next is the casting process. In general, low pressure casting machines, casting is good, a mold can be several sets of products, high production efficiency. Cast out of the product wall thickness, higher density, the cavity is smooth, thin wall for large, complex castings, forming more favorable, and its yield is much higher than gravity casting. The third step is machined, raw materials (stainless steel, copper materials, aluminum materials, iron materials, etc.), with lathes, milling, drilling and other machinery by drawing or sample processed into a variety of parts. This process need to use sophisticated equipment, the scale must be accurate. Fourth process is grinding and polishing. Grinding and polishing into roughing and finishing, with a fast-moving belt product rough surface grinding; using high-speed rotating grinding wheel or a burlap polishing machine for metal surface processing, making it smooth and bright, increase brightness and finish the product. After grinding and polishing process, the need to detect whether a qualified technician, failed to draw a circle on rework, inspection is very strict. Metal electroplating process, so that the use of electrolysis, or other metal parts attached to the surface of the material layer of metal film, which serves to prevent a metal oxide (such as corrosion), to improve wear resistance, electrical conductivity, reflectivity, corrosion resistance (acid copper, etc.) and to increase the aesthetic effects. To enhance the silky feel, so soft appearance, color and timeless, top solid metal plating process after multilayer, will conduct a comprehensive inspection of the defective product rework, to ensure the integrity and flawless. Next, the assembly tool to assemble and parts, machined metal parts according to a certain order and technologies to connect together into a complete set of hardware products. This process is the key to determine the quality of products. Finally, test the product switches feel, feeling ahead of the user experience, allowing customers to use the product for the first time there will be high-quality enjoyment; wipe the appearance of the product, test the product, so that products remain smooth and clean; coupled with accessories, into the specified packing boxes, placed outside the box, according to the process of storage. Production of high-quality hardware, inseparable from a complete production line, production staff can not do without careful, rigorous work!
