1)Resin sand casting is a general designation, in front of the modelling, the core sand on the surface has been covered with a layer of solid resin membrane sand, known as the core sand coated sand, also known as the shell mold (core) sand.

2) It is a kind of thermosetting resin sand, the earliest by the German Dr Cronin (CRONING) was invented in 1944.

3) Resin sand casting is the original sand and resin blend to form the resin sand, resin sand into the mold cavity, by heat or catalyst method makes its forming, after forming the palatial core in the casting mould in the casting.

4)Resin sand casting with a small surface roughness, high dimensional accuracy, good quality characteristics.

5)Resin sand casting between casting and mold block isolation effect, achieve the adhering sand, also can effectively prevent the oxidation of the high temperature liquid metal, make the mold and in the process of the high temperature liquid metal contact no chemical reaction, and can absorb nitrogen, sulfur and carbon gases.
