A metal caster works in a foundry, which is a place that is specifically designed to handle hot metals. There is a central fire area or forge that allows for the heating of the metal to make it liquid. A caster then takes the molten liquid metal and pours it into casts or molds to form metal shapes that are then sanded, grinded, and polished before being finished. A caster works with all types of metals and different molds. Some casters make their own molds or casts from different materials such as metal, wax, and sand.
The caster must work with different types of metals and understand the different methods of liquefying them. Some metals are softer and melt at a lower temperature and some metals like iron and bronze only melt at very high temperatures. An expert caster knows the differences in metal types and is able to work with them in different fire ovens to get them to the correct temperatures for casting.
A metal caster may work with large pieces for industrial molds or something as small as cast jewelry from gold and silver. A metal caster can work in all types of industries, allowing for different options in career choices.
The caster is responsible for measuring the amount of metal to be heated. They then heat the metal in the fire and regulate the temperature to keep the metal at a certain pouring temperature. Casters are responsible for making sure that the mold is clamped and secure so that the molten metal can be poured into the mold. The caster pours the molten metal into the mold via a ladle or other device. Once the mold has cured, the caster uses different tools to grind down the metal piece and polish it.
A metal caster works with all types of machinery and tools including:
A caster is also responsible for the molds and their maintenance. They must make sure that the molds are clean and smooth so that they can accept the liquid metal.
