(Summary description)Investment casting, also known as investment casting, is a precision casting process with very little or no laser cutting. It is a production process in the field of precision casting, and its use is very common. It can not only be used for precision casting of various types and metals, but also produces castings with higher dimensional precision and surface quality than other precision casting methods. Castings that are more complex, heat-resistant, and less prone to production and processing can be used. High precision precision casting. The true application of contemporary investment casting methods in industrial production was in the 1940s. At that time, the advancement of aviation companies' turbojet engines required the production and manufacturing of wear-resistant alloy steel components, such as leaves, centrifugal impellers, nozzles, etc. They had complex shapes, accurate specifications, and smooth surfaces. Because wear-resistant alloy steel raw materials cannot be produced and processed, the appearance of components is so complex that they cannot be or cannot be produced in other ways. Therefore, it is necessary to find a new high-precision forming and processing technology, so that the wax loss precision casting, which has been widely passed down from ancient times to today, has achieved a crucial development trend in contemporary investment casting through the improvement of raw materials and processing technology. Based on the long-standing new technologies. Therefore, the progress of the aerospace industry has promoted the application of investment casting, and the gradual improvement and enhancement of project investment in precision casting have also created resource advantages for the aerospace industry to further improve its sales performance. Investment casting is based on ancient wax molds for precision casting. As a civilization with a long history, China was one of the regions that initially applied these new technologies. In the hundreds of years before British Columbia, ancient Chinese laborers developed this type of precision casting technology for precision casting, with various detailed pattern designs. There are also words for watches, clocks, containers and other commodities, such as Zeng Houyi's tomb in the Spring and Autumn Period and the Warring States period. The industrial base of Zeng Guyi Tomb is a pair of intertwined dragons. They are connected head to tail, interleaved from left to right and sequenced to produce a double-layer Weather map in the middle. This pattern design cannot be produced and manufactured according to ordinary precision casting processes. The precision casting process can utilize the objective fact that paraffin has no compressive strength and is easy to carve by hand. With ordinary specialized tools, it can manually carve works of art like lime powder, such as the Yi Tomb of Zeng Kiln. Then, by adding pouring system software, architectural coatings, dewaxing, and pouring, exquisite Zeng Kiln tombs can be obtained. The characteristic of investment casting is that investment castings have high dimensional precision and surface smoothness, which can reduce production and processing work. However, as long as there is a small amount of machining remaining on the parts, even some castings only have cutting and polishing capacity and can be applied without production processing. It can be seen that investment casting precision casting method can save a lot of mechanical equipment and production time, greatly saving metal materials and raw materials.
