Development trend of investment casting

Investment casting is one of the basic processes of modern machinery manufacturing. The development of casting industry indicates the production strength of a country.China has become one of the largest casting machinery countries in the world and has made great achievements in casting machinery manufacturing industry.

During the eighth five-year plan period, casting machinery manufacturing was highly valued by the original electromechanical department.It invests in the largest special technical reform loan and research costs since the founding of the People's Republic of China, and supports the development and development of products in the foundry machinery industry."Large shot blasting machine", "vertical split-type box-less injection molding machine", "development of water glass sand recycling equipment", "metal casting equipment" have been developed and applied.

During the ninth five-year plan period, the foundry machinery industry undertook and completed the task of "finishing and refining automobile casting efficient modeling and cleaning technology", as well as the development and development of "efficient continuous shot blasting".Cylinder line "was also successful.In 1999, the country successfully completed the advanced gas stamping forming line project.

During the tenth five-year plan period, the main economic indicators of the foundry machinery industry grew at an average annual rate of more than 30%, higher than the average growth rate of machine tools and the whole industry.In addition, complete equipment for resin sand casting can basically meet the needs of the domestic market and change the past situation of relying mainly on imports.It has been able to produce a higher level of automatic casting line that can partially replace the imported level and partially solve the automotive engine.Also must import cylinder and cylinder head and other casting;China can produce advanced automatic core machine, automatic casting cleaning machine, automatic sand processing machine, large automatic die-casting machine, precision casting equipment and other casting machines..It should be said that during the tenth five-year plan period, the product level of foundry machinery industry has been greatly improved, which has laid a good foundation for the further development of China's foundry machinery industry in the future.

During the eleventh five-year plan period, the foundry industry will continue to maintain a high growth rate under the stimulation of huge market demand.There is still a big gap between the technical level of casting machinery products and the market demand, so the industry development has great development potential and expansion space, which brings opportunities for the rapid development of casting machinery industry.

When considering the above three aspects, the main basis is still the basic principle of general casting process, especially when determining the process program and process parameters (such as casting round corner, mold inclination Angle, machining allowance, process rib, etc.).Except for the specific data, the design principle is the same as that of sand mold casting, because the process characteristics of investment casting are slightly different.
