Cast stainless steel castings press fitting custom processing

Cast stainless steel press fittings casting process can be customized to adapt to different requirements of different steel workpieces. Due to the formation of surface nitriding technology with excellent performance, and nitriding process and die steel quenching process are well coordinated, but after nitriding temperature hypotonic nitrogen without intense cooling, mold deformation is very small, so the mold surface strengthening nitriding technology is the use of older, is the most widely used. Cast iron plate mold carburizing main purpose is to improve the overall strength and toughness of the mold, that the working surface of the mold with high strength and wear resistance. Thus the introduction of technical ideas is to use a lower grade material, i.e., by carburizing material instead of a high level, thereby reducing manufacturing costs. Die Casting classification in many ways, often used in the past are: by casting mold structure in the form of classification, such as single-process mode, double die etc; by using object classification, such as auto cover casting molds, casting molds and other motor used to use a casting mold comprehensive classification method of shaping the nature and use of object-oriented technology, and the casting mold is divided into ten categories, but also according to the casting mold structure, materials, functions and molding methods is divided into several categories or varieties. Produced by conventional sand casting precision forging low, long molding cycle, casting surface quality will not be able to achieve the requirements of rotational molding, manual polishing needed after casting. In the process, the extensive use of CNC machine tools not only to ensure the precision and quality die cast aluminum parts, but also with high cutting speed, high feed rate and high processing quality as the main feature of the processing technology to improve efficiency than conventional machining times or even ten times. Therefore, die cast aluminum to produce rotational necessary to use precision forging methods, while the introduction of rapid tooling technology to shorten the mold manufacturing cycle. At present, the rapid development of more mature modeling methods are laser modeling method SLA, thin-layer method LOM, FDM fuse deposition and selective laser sintering SLS and so on. Although China is the world's largest producer of foundry machinery, but not producing power. Italian casting machinery production technology in the world advanced level. Our casting machinery production has ranked first in the world for several years, but the production of low-end products, but also to small businesses within the industry mainly fierce competition within the industry. In recent years, with the shift of global manufacturing, global foundry machinery multinationals are gradually entering the Chinese market, and gradually occupied the domestic high-end market.
