Sand casting uses disposable sand molds, not permanent molds.
Made of materials like clay sand, the molds must be broken down after a single casting to remove the casting and cannot be reused.
Mold Characteristics
Sand casting molds are consumable and must be remade after each casting. This is fundamentally different from the permanent molds used in metal casting (made of materials such as steel or cast iron, which are reusable).
Applications
Sand casting is suitable for single-piece/small-batch production, and is particularly well-suited for casting complex structural parts (such as engine blocks) or special alloys (such as cast iron and cast steel).
What is the typical lifespan of a sand casting mold?
Sand casting molds are disposable and consumable, and their lifespan is generally defined by the number of times they can be used in a single casting. Unlike the permanent molds used in metal casting, sand casting molds (such as clay sand or water glass sand) must be broken down after a single pour to remove the casting and cannot be reused. This characteristic makes it particularly suitable for single-piece/small-batch production, especially for casting complex structural parts (such as engine blocks) or special alloys.
Specific Representations of Mold Life:
Single-Use Life: A sand mold’s life spans the entire production process from its creation to the completion of a single casting, typically a single use. For example, green sand molds and water glass sand molds collapse after pouring and require remaking. Therefore, sand casting molds require remaking after each casting.
