Brief Introduction of the precision casting technology
Science and technology is the first productivity, with more than ten years reform and opening up, the industry has been developing rapidly, precision casting therefore have a good opportunity of development, precision casting is widely used in aerospace, electronics, petroleum, chemical industry, transportation, equipment, shipbuilding and other industries, whether it is the modernization of industrial demand, or the demand of agricultural machinery and the needs of daily life cannot without the existence of precision casting.
Compared with the traditional casting, precision casting can obtain relatively accurate shape and high precision casting. The so-called precision casting process, simply is to make the fusible material into fusible model, in the refractory coating special several layers of the fireproof coating, after drying and hardening to form a whole body shell, and then steam or hot water from the shell in the melt model, and then the shell into the sand box, filled with dry sand molding around, finally will cast into the furnace after calcination at high temperature, mold or mold shell roasting, in which the pouring of molten metal and casting.
At present, there are two kinds of precision casting technology: the lost wax casting precision casting and pressure forming precision casting technology.
Lost wax casting now called precision casting, is a kind of less cutting or no cutting precision casting process, is a superior technology of precision casting industry, its application is very extensive. Precision casting it not only applicable to all types, all kinds of alloy, and production of casting dimension precision, surface quality than other precision casting method must be high, and other precision casting method to cast the complex, high temperature resistant, not easy machining castings, can use the method of precision-investment casting to obtain.
Pressure forming precision casting technology is a new kind of casting technology which invested from the production problem of casting of large complex thin-walled parts. Using the technology of production of large complex thin-walled castings, can obtain the filling capacity and better feeding capacity, the grain refinement of castings, density, improved performance. With the continuous research and development of this technology, the application effects and scope of application has been continuously strengthen and expand. The current voltage forming precision casting technology has been applied in aerospace engineering for large complex thin-walled aluminum alloy castings in production, technical efficiency is very obvious.
