• Product Description
  • Lost foam coatings, also known as expendable pattern castings, is a unique process in metal casting where a foam pattern, typically made of polystyrene, is used to create a mold cavity. This pattern is coated with a refractory material, such as sand, to form the mold. When the metal is poured into the mold, the foam pattern burns away, leaving behind a void that is filled with the molten metal.

    The lost foam process offers several advantages, including the ability to cast complex geometries that are difficult or impossible to produce using traditional casting methods. It also allows for the production of lighter, more porous castings with improved heat transfer characteristics. Furthermore, the process is relatively inexpensive and environmentally friendly, as it generates little waste and requires less energy than some other casting processes.

    Lost foam coatings are used in a wide range of applications, including automotive, aerospace, and other industries where lightweight, heat-resistant components are required. The versatility and efficiency of this casting method have made it a popular choice for manufacturers seeking to improve product quality and reduce production costs.
