The advantages and development prospects of Dongguan precision casting
Investment casting refers to the use of fusible raw materials to make a fusible solid model, and apply several layers of specially made fireproof architectural coatings on it. After drying and hard bottoming to produce an overall shell, steam or Boiling water melts the solid model from the shell, then puts the shell in the sandbox, fills it with dry sand around it, and puts the mold in the calciner to undergo high temperature sintering, and the mold or shell is sintered , Pouring molten metal materials in it to obtain castings.
The products obtained by investment casting are high-precision, diversified, close to the appearance of parts, and are immediately applied without production or processing or very little production and processing. It is an advanced technology with near net shape and an excellent in the field of casting. The production process is very common. It is not only suitable for casting of various types and various aluminum alloys, but also the precision and surface quality of the castings produced are higher than other casting methods, and even other casting methods are difficult to cast. , Castings that are not convenient for production and processing can be cast by investment casting.
At this stage, the global investment precision casting molding processing technology is developing rapidly and widely used. From the current trend, the future development trend of the processing technology in the future is that the casting products are getting closer to the parts and components. The traditional precision castings are only As a raw material, it is no longer suitable for the rapid resilience of the sales market. The level of complexity and quality of parts products is getting higher and higher, product research and development methods are becoming stronger and stronger, professional collaborative work is gradually emerging, and the application of CAD, CAM, and CAE has become the key technology of parts product research and development.
Analyzed from the current development trend situation, the application of precision casting technology in Dongguan is very common, and its development prospects in the future are quite broad.
