Core sand is used for making cores and it is sometimes also known as oil sand. Core sand is highly rich silica sand mixed with oil binders such as core oil which composed of linseed oil, resin, light mineral oil and other bind materials. Pitch or flours and water may also be used in large cores for the sake of economy. 2.3 Dry sand

It describes the two methods for preparation of resin-sand mixture for shell molding, namely, mixing resin and sand according to conventional dry mixing techniques, and coating the sand with resin. Shaping of shell molds and cores from resin sand mixtures is accomplished in machines.
The preparation of the sand molds (cores) should be avoided as much as possible in the "inverted trapezoid" structure. In view of the above, the complicated sand molds (cores) are very difficult to prepare via SLS, and it is impossible to prepare the complicated sand molds (cores) like hydraulic valves using the previous research results. ...
When the sand molds (cores) are prepared in the conventional method, the sand molds are often divided into several pieces to be prepared separately, and the sand cores are, respectively, pulled out to be assembled, so it is necessary to consider the problems of assembly positioning and accuracy.
In practice, cores and molds produced using organic heat- and amine-cured resins were dipped or immersed in the ethanol solution, dried, and subsequently fired in a kiln to convert the organic-bonded …
