In making larger ones, there is a greater weight of sand to cause strain in handling the core,and proportionately greater casting strain. To resist these stresses a systematic network of rods is bedded in the core while being rammed, as shown in the sectional view, Fig. 66. Heavy bars aabb extend the length of the core to give the main stiffness.

A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in die casting and injection moulding.
Principles Of Core Work. Part 2. These conditions are obtained by using a coarse free sand and a binder. To give additional strength when necessary, iron wire or rods, or cast-iron core arbors are bedded in the core. These serve the same purpose in a core that the flask does in green-sand work. Binder. The action of the binder enables the sand to retain its shape when the box is removed, and ...

From the design, provided by a designer, a skilled pattern maker builds a pattern of the object to be produced, using wood, metal, or a plastic such as expanded polystyrene. Sand can be ground, swept or strickled into shape. The metal to be cast will contract during solidification, and this may be non-uniform due to uneven cooling.

The working principle of a sand slinger machine is shown in Fig. 4.11 (c). As can be seen, moulding sand is fed into a housing containing an impeller that rotates rapidly around a horizontal axis. Sand particles are picked up by the rotating blades and thrown at a high speed through an opening onto the pattern, which is positioned in the flask.
