Sand casting – casting method for producing castings in sand molds. Steel, iron and most ferrous alloy castings can be obtained by sand casting. As the molding material used in sand casting is inexpensive and easy to be manufactured, the …

1. Pinhole Actions to prevent the pinhole happen: it is forbidden to use the contaminated cast aluminum alloy material, the organic compound and the material which has been seriously oxidized. Control smelting process, strengthen the degassing refining. Control the thickness …

Low pressure casting is widely used in metal processing, play a huge role in the modernization of our industry, along with the low-pressure casting widely used in our country, it brings disadvantages also will be exposed. First, the oxide slag …

According to the “2013–2017 China’s iron and steel casting industry sales forecast and upgrade needs analysis report” statistics, in 2012 China’s total output of 42.5 million tons of various types of castings, compared with 2011 growth of 2.4 percent year …

Cast molding is generally not exert pressure on the less demanding strength equipment and molds for products small size limits the stress within the article is also low. Thus, less productive investment, good performance large parts can be obtained, but …

Casting process simulation uses numerical methods to calculate cast component quality considering mold filling, solidification and cooling, and provides a quantitative prediction of casting mechanical properties, thermal stresses and distortion. Simulation accurately describes a cast component’s quality up-front before production …
