In the last issue, we talked about the surface treatment processes that are often used in the post treatment of handboards: grinding, sandblasting, polishing, spraying, powder spraying, and UV spraying. Then today we will talk about other post-treatment surface treatment processes: printing, radium carving, electroplating, oxidation, blackening, wire drawing and phosphating. (Oxidation, blackening, wire drawing and phosphating are only applicable to metal parts) 1 Printing (1) Silk screen printing: part of the mesh of the screen printing plate can pass through the ink and miss printing to the substrate; The mesh of the rest of the plate is blocked and cannot…

Samples are produced by numerical control equipment, 3D printing, and copying. In the rapid prototyping process, in addition to high-quality machine processing, in most cases, it may also require a lot of manual or other instruments for post-processing operations. For general appearance products, it is required that the surface treatment should be as close as possible to the finished products before the appearance effect can be tested. Common surface treatment processes mainly include: grinding, sand blasting, polishing, spraying, powder spraying, UV spraying, printing, radium carving, electroplating, oxidation, blackening, wire drawing and phosphating. (Oxidation, blackening, wire drawing and phosphating are only…

With the increasing aesthetic and functional requirements of the product, the internal structure of the product is designed more and more complex, and the shape design of the mold is more and more complex. The proportion of free surface is increasing, and the corresponding mold structure is more and more complex. All of these put forward higher requirements for mold processing technology. High speed machining technology has been increasingly used in mold cavity processing and manufacturing. Compared with the traditional cutting, the cutting speed and feed speed of CNC high speed cutting have been greatly improved, and the cutting mechanism…

What is stamping? Stamping is a forming processing method of workpieces (stamping parts) with required shape and size by applying external force on plates, strips, pipes and profiles by press and die to cause plastic deformation or separation. The car body, chassis, fuel tank, radiator sheet, boiler drum, container shell, motor, electrical iron core silicon steel sheet, etc. are all processed by stamping. Instruments, household appliances, bicycles, office machinery, household utensils and other products also have a large number of stamping parts. According to the stamping processing temperature, it can be divided into hot stamping and cold stamping. The former is suitable…

At present, CNC high finish machining process (milling, turning) is not well known by technicians in most industrial industries. The actual work shows that they are really controlled by only a few production enterprises. The main reason is that the demand is not very strong in the past, which is also closely related to cognitionIn recent years, with the development of high-performance and high-precision CNC machine tools and the emergence of high-performance metal cutting tools, CNC high finish machining has made a great breakthrough. It is possible to replace grinding with milling (turning), which has become the goal pursued by…

Generally, hot stamping is to heat the steel plate to about 900 ℃ austenite before stamping, and then cool the parts by rapidly injecting water into the stamping die. Through this thermal cycle and cooling process, the strength of the steel plate can be greatly improved, and the tensile strength can be increased from about 500MPA under delivery to about 1500MPa after hot stamping. According to different processes, hot stamping can be divided into direct hot stamping and indirect hot stamping. 01 Direct Hot Stamping Technology After blanking, the hot formed steel plate is directly heated to the austenitizing temperature without…

Aluminum alloy has long existed in our life, but in recent years, it has become the representative of Gao Fushai through the application of high-tech products. Especially in the competition of mobile phone design in recent years, Apple, Samsung, Meizu, Xiaomi, Huawei and others have made great efforts in the use of materials and processing technology Because of its easy processing, good visual effect and rich surface treatment methods, aluminum is the first to be used by various manufacturers. The surface treatment of aluminum profiles is mainly divided into: sandblasting (forming a matt pearl silver surface), polishing (forming a mirror…
