1 1.Metal castings are obtained by pouring molten metal into cavities formed in sand or metal molds and allowing the metal to solidify: In the making of sand molds, suitable mixtures of molding sand are rammed around patterns which are removed after the impression has been produced. In order to compensate for the contraction of the metal when it solidifies and cools, the pattern are usually made somewhat larger than the dimensions required on the finished castings.
2.Construction of sand molds. A sand mold is made within a frame of wood or metal known as a flask which may be of any size or shape to accommodate the pattern to be used in it. Each flask has two or more sections, depending upon the design and size of the castings to be produced. The top section of the flask is the cope, the bottom section is the drag, and any intermediate sections are the cheeks. Pins and lugs are attached to the flask to insure positive alignment of all sections when the mold is closed. A bottom board supports the sand in the drag. In order to carry the sand in the cope of a large mold, bars are fastened securely across this section of the flask. The mold cavity contains, in addition to the impression for the casting, one or more openings known as gates through which the molten metal enters the mold. The gate includes the basin into which the metal is poured directly from the ladle and all parts of the passage way leading from the pouring basin to the cavity in which the casting is formed. The gate consists of the pouring basin, the sprue, the runner and the in-gate.
3.The pouring basin receives the molten metal and discharges it into the sprue. The sprue is the vertical portion of the gate which conveys the molten metal from the pouring basin to the runner. The runner is the horizontal portion of the gate which distributes the molten metal to one or more castings in the mold. The in-gate is the opening from the runner to the cavity in which the casting is formed. The location and size of gates are arranged so that the molds can be filled quickly with the minimum amount of cutting of the mold surfaces by the flowing metal. Attention is also given to the placing of gates so as to avoid the development of cracks when the metal cools.

The gate does not consist of the pouring basin
