The Sand Casting Process
Casting bells in bronze offers many advantages. The metal is durable and is highly resistant to corrosion. A wide range of forms and sizes is possible, and, most importantly, the bells ring with a strong, pure tone that is unique to bronze. The drawing below illustrates the essentials of sand casting. First a pattern is made that resembles the finished piece. Sand is packed around the pattern to form a mold impression. This is much like making footprints on wet beach sand. In fact a passable casting of one's footprint could be made by pouring plaster or molten bronze, for that matter, directly into the impression in the beach sand. After the mold is packed, the pattern is removed and bronze can be poured into the finished mold to form the casting. If you click on the different areas of the drawing, you can read more detail about our casting process. |
