  • Product Description
  • Lost foam special sand, also known as expendable pattern sand, is a unique material widely used in the casting industry. This sand, composed primarily of special refractory grains, is specifically designed to replicate the shape and structure of a desired casting. Its application process involves packing the sand around a foam pattern, which is then melted away, leaving an impression in the sand that corresponds to the pattern's shape. This impression is then filled with molten metal, resulting in the formation of a cast part that is identical to the original foam pattern.

    The lost foam process offers several advantages over traditional casting methods. One significant benefit is the ability to create intricate and complex geometries that would be difficult or impossible to achieve with other techniques. Additionally, the process results in a cast part with a smooth surface finish, minimal porosity, and excellent dimensional accuracy.

    Lost foam special sand is also noted for its ability to withstand high temperatures without losing structural integrity. This allows for the production of castings in a wide range of materials, including ferrous and non-ferrous metals. As a result, lost foam casting has become a popular choice for manufacturing a diverse array of parts, including those used in the automotive, aerospace, and heavy machinery industries.
