Sand casting foundries é uma fábricas muito específicas e fazem uma espécie de magia em metal. Those pieces can be large or small, simple or complex, but they all begin with sand. The sand is first placed in a box and compressed into a mold. Finally, hot metal is poured into the mold, and it sits and cools. After the metal has set, the sand is removed to reveal the completed piece. It’s kind of like building a sandcastle, only using metal instead of sand!
Designs, in simplest form, are plans showing how a metal part should be. These designs are used by sand casting foundries to produce molds that form the metal. Molds are formed by packing sand around a pattern that mirrors the part design. The pattern is shaped like the cavity that will be shaped inside of the hot metal that will be poured in. At a sand casting foundry, this is what it looks like when designs come to life — when drawings become actual parts used in things like machines, cars and other ‘big deal’ things.
Sand casting foundries use a special process for the manufacturing of metal parts. The process begins with creating a pattern of the part which is used to construct a mold in the sand. Hot, melted metal is poured into the mold and allowed to cool. After the metal solidifies, the sand is disassembled to reveal the completed piece. It requires caution and skill during the process to ensure the metal part is created correctly. When making sand casting parts, foundries must adhere to every sartorial step to ensure they deliver high quality components that are fit for purpose.
This method can produce metal components and parts in virtually any size or shape, so sand casting foundries are ideal for applications requiring anything from small mechanical gears to larger machine components. The process allows them to add finer details to the parts, so they function properly when used. They can also utilize various types of metals such as aluminum, bronze, and iron. This flexibility enables them to produce parts for so many industries — airplanes, cars.
However, sand casting foundries remain common today, even with new technology available. This is because sand casting represents an efficient and economical method for the fabrication of metal components. The process is fairly simple and requires little hardware, which make it easy for most companies to implement. In addition, sand casting can produce one-off parts that may be challenging or expensive with other processes. So, foundries using the sand casting process remain a key part of the manufacturing process for metal parts across many industries worldwide.
