An advantage can produce castings of complex shape parts, particularly complex cavity blank (such as heating) 2 wide adaptability, commonly used industrial metal materials can be cast. A few grams to several hundred tons. Extensive three sources of raw materials. Low price. Scrap, scrap, shape and size of the chip 4 castings and parts are very close, cutting the amount of reduction, is no less cutting. Our country is in the 1950s and the beginning of the sixties the investment casting used in industrial production. Later this advanced casting process has been tremendous development, have been in the aerospace, automotive, machine tools, ships, internal combustion engines, gas turbines, telecommunications equipment, weapons, medical equipment and tools and other manufacturing industries are widely used bucket wheel guard dock equipment, Also used in the manufacture of arts and crafts. The so-called investment casting process, it simply is to use fusible material (such as wax or plastic) fusible model (referred to as the melting mold or model), which is coated in several layers of a special fire-resistant paint dock equipment, after drying and after hardening to form a whole shell, then steam or hot water from the melting away of the shell model pier streamer tank equipment, and then placed in the sand box shell, filled with dry sand around it in the shape of terminal equipment manufacturers, and finally The mold into the roaster in the high-temperature calcination (such as the use of high-strength shell, may not have to shell shape and direct the firing after stripping), after the mold or shell after roasting, in which molten metal pouring get castings. Terminal equipment manufacturers, Chen Hua machinery (certified), the terminal equipment provided by China Machinery Equipment Co., Ltd. Qingdao Chen. Qingdao Hua Chen Machinery Co., Ltd. (www.qdchenhua.com) is Qingdao, a leader in CNC machine tools over the years, the company implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chen Hua Machinery leadership in the staff warmly welcome all inquiries negotiations to create a better mechanical Chen Hua future.
