2010 development trend of precision casting
2010, the most talked about topic of environmental protection, a series of measures for environmental protection requirements of the world’s foundry industry is bound to pose serious challenges, in November 2010 for high energy consumption of China’s electricity producers had strict control, especially the casting, stainless steel melting high energy consumption, high pollution enterprises the most stringent power control, some companies have suspended production, can only be possibl...
Application of Laser Forming and Casting
Fast automatic molding technology developed in recent years the rapid production directly from the cad model sample or part of the general term for group technology. The technology to solve a computer-aided design (cad) in the three-dimensional modeling of the “seen, touched,” the problem, the geometry of the screen can quickly auto-entity. It integrates cad technology, numerical control technology, laser technology and materials technology and other modern scientific and technologic...
Sand Casting Brief
According to statistics by sand casting priority Casting production in all, 60 ~ 70% of sand casting is produced, and about 70% of which is clay sand production. Mainly due to sand casting and low cost compared to other casting methods, production process is simple, short production cycle. So as the car engine cylinder block, cylinder head, crankshaft, etc. are used for green sand casting process production. When the wet type can not meet the requirements and then consider the use of clay, sand ...
Precision casting tolerance
High size precision casting, generally up to CT4-6 (sand casting for the CT10 ~ 13, casting for the CT5 ~ 7), of course, the investment casting process complex, dimensional accuracy of castings are many factors, such as mold material shrinkage, melting mode of deformation, shell in the process of heating and cooling the amount of change in the line of the alloy during the solidification shrinkage and deformation in the casting, so the size of an ordinary precision castings though high, but still...
