Sand Casting Process

The Cosworth process 39 is a low-pressure sand casting process used to obtain sound castings. An electro-magnetic pump fills molten aluminum from the bottom of the resin bonded mold. Large cylinder blocks have been produced using this method. Core package system 40 is a sand casting process proposed by Hydro Aluminum.

Optical dating of dune sands in the northeastern deserts …

2002-6-25 · Abstract. Optical dating has been used to obtain the ages of fossil-stabilized sand dunes from four sections in the northeastern deserts of China. Our results indicate that the optically stimulated luminescence ages of the four sections correlate well, even though the samples were collected from different deserts about 600 km apart.
