EPC is common microstructure and a wilt of watermelon type, most is extremely dense, captured by the white mold gasification heat fast cooling shell layer, if heat temperature decreased seriously, there will be some models the orange peel phenomenon disappeared. >>>>>>> international casting industry and beauty casting mall on-line version, to send thousands of merchants settled in decoration!

It is equivalent to self cooling iron, followed by normal casting microstructure, casting properties on the basis of the formation of normal growth in the self cooling iron foundation.

If the high temperature of hot metal, pouring, some technical flaws, casting central feeding may problems -- generates porosity, shrinkage pine, it is a very bad phenomenon.

Once a force is exerted a strong impact, it is possible to cause broken -- for example, gravity hammer, without breaking the upper central support, then break the lower. Seriously affect the use of castings. However, a lot of time, the use of castings, there is no strong impact of external shocks.

May your users are very professional, the provisions of the body of a tensile test specimen in casting the most likely problem of central, and 20 mm so prone to causing the critical thickness of the density.
