Precision Casting Precision Is Very High

- Aug 02, 2017 -

Precision casting is the world leader in foundry industry, as the foundry industry in the high and new field of representatives, precision casting must play its exemplary role and lead role, but the precision casting to play these two functions of the premise is strong itself, so China's precision casting should be prioritized development, development needs the established policy and development goals.

Precision casting belongs to special casting. Parts that are cast in this way do not need to be machined, or can be used with a small amount of processing. Investment casting and die casting.

Precision casting, which belongs to a kind of net near-forming casting technology, using the method of precision modelling, can cast

Castings with high precision, very complex shape and very thin thickness. Precision Casting Compared with the ordinary casting method, its casting precision is very high, the shape of the casting is also very complex, can be processed with little or no processing, and can be mass production. Therefore, the precision casting process plays a very important role in the production process of our country.

China is a manufacturing country, it is clear that precision casting technology has been widely used. There are many kinds of precision casting technology, mainly including: investment casting technology, metal casting technology, die casting technology, EPC technology, etc., Precision Casting but the most commonly used is investment casting technology. In this paper, the precision casting technology of transmission support and the common welding technology are compared and analyzed, from the aspects of cost and production cycle.

China is a manufacturing country, it is clear that precision casting technology has been widely used. There are many kinds of precision casting technology, mainly including: investment casting technology, Precision Casting metal casting technology, die casting technology, EPC technology, etc., but the most commonly used is investment casting technology. This paper mainly through the precision casting technology of transmission support and the common welding technology to the precision casting process, also known as lost wax casting technology, through this method of processing products are very sophisticated, shape is very complex, and the final shape of the parts almost the same, Precision Casting need to be processed in the place is very few or directly available products, therefore, investment casting technology is a form of advanced technology. Early in the last century 40 's, the process of investment casting technology has been widely used, such as copper lion products, copper products, such as the use of investment casting technology produced. At present, the process of investment casting technology is applied in all walks of life, Precision Casting such as transportation industry, aerospace industry, energy industry, pharmaceutical industry and so on, and rapid development. Through the precision casting technology, not only can produce small castings products, but also can produce large castings. The contour dimensions of the largest investment castings produced by this method are nearly 1.9mm, but the minimum wall thickness is thinner than 2mm. In addition, precision casting technology has been continuously refined

In addition to the linear tolerances of castings, the casting products can achieve high geometrical tolerance parameters. Precision Casting Technology Casting product surface roughness is also very low, has been close to Ra0.3um. In view of these advantages of precision casting, it has been widely used in Chinese industry. Precision Casting In addition, through this precision casting process, can save a lot of machining time, shorten the entire production cycle of casting products, and also greatly improve the utilization of casting materials, the cost of casting parts of the product is also reduced, the production of castings product quality is very high. 3, precision casting process in the production of the application welding drive support, it is a transmission bearing structure, complex shape, the welding technology is used to process the production, it first needs the parts to be processed, and then assembled, Precision Casting and soldering to make it a whole piece, processing time is longer, and the quality is not guaranteed (the bearing has the possibility of deformation). Through the analysis of the whole structure of the transmission support, and the selection of materials and the design of geometric size analysis, the final use of precision casting technology to process forming is the best choice, and the quality of casting products is very high, Precision Casting only a very small number of important size selective processing. Precision casting transmission support is a transmission bearing which is machined by the precision casting process.

Comparing the two processing methods, we can see that there are significant differences in the time and cost of processing production, and the economic benefits they bring are not the same in mass production.
