Cope and drag with cores in place on the drag Two sets of castings (bronze and aluminium) from the above sand mold. In foundry work, the terms cope and drag refer respectively to the top and bottom parts of a two-part casting flask, used in sand casting. The flask is a wood or metal frame, which contains the molding sand, providing support to ...
A similar technique called a cope and drag pattern is often used for large castings or large production runs: in this variation, the two sides of the pattern are mounted on separate pattern plates that can be hooked up to horizontal or vertical machines and moulded with the molding material.
The cope and drag (top and bottom halves, respectively) of a sand mold, with cores in place on the drag. Two sets of castings (bronze and aluminium) from the above sand mold. Sand casting , also known as sand molded casting , is a metal casting process characterized by using sand —known as casting sand —as the mold material.
Molding material: The material that is packed around the pattern and then the pattern is removed to leave the cavity where the casting material will be poured. Flask: The rigid wood or metal frame that holds the molding material. Cope: The top half of the pattern, flask, mold, or core. Drag: The bottom half of the pattern, flask, mold, or core.
The shape of a flask may be square, rectangular, round or any convenient shape. A flask can have any size so long as it is larger than the pattern being used to make the sand mold. Flasks are commonly made of steel, aluminum or even wood. A simple flask has two parts: the cope and the drag. More elaborate flasks may have three or even four parts.

Produce wax patterns: Although called wax patterns, pattern materials may also include plastic and frozen mercury. [6] Wax patterns can be produced in one of two ways. In one process, the wax is poured into the mould and swished around until an even coating, usually about 3 mm (0.12 in) thick, covers the inner surface of the mould.
