Certain components don’t necessarily have the casting mold to reproduce them properly. Companies that need effective fabrications of these complex parts can count on Fountain Foundry to produce them using our cope and drag services.
Defining Cope and Drag
Cope and drag are the top and bottom parts of a cast that is instrumental in sand casting. The cast is usually wooden or metal, supporting the sand in the casting process.
The drag is placed on a board around the pattern to be cast. Sand is shifted to the pattern until it is covered with a few inches of sand. A board is placed on top of the drag and flipped over before the cope is placed on top of it. Dowels are put in the sand for the sprue and risers. Sand is refilled to the pattern and made to fill the cope.
The pattern is pulled from the sand as a cavity is left behind. A passageway for the metal to enter the mold is made into the sand. Then the flask is put back together, and metal is poured into the mold.
Cope and Drag Applications in Sand Casting
Cope and drag are instrumental in the sand casting process, as it would be impossible to get a workable mold without either of the two parts. They provide the necessary support so the sand can adequately work on the molten metal.
The process is relatively inexpensive and is usually done for bigger components.
