The raw material choice for precision casting depends on the final product's properties and the casting process, making it versatile, cost-effective, and widely used in various industries.

Precision casting is a manufacturing process that involves the production of metal parts through the casting of molten metal into precision molds. The raw materials used for precision casting primarily consist of metal alloys and other materials that can be melted and cast into shape.

The most commonly used raw materials for precision casting are metal alloys, which are combinations of two or more metals that have been mixed together to create a new material with specific physical and mechanical properties. Metals used for precision casting include ferrous alloys such as iron, steel, and stainless steel, as well as non-ferrous alloys such as aluminum, copper, zinc, and titanium.

For precision casting, the metal alloys are usually melted into a liquid form and then poured into a precision mold where they solidify and take on the shape of the mold cavity. The precision mold is typically made using a wax pattern or a ceramic shell and is designed to replicate the desired geometry and surface finish of the metal part.

In addition to metal alloys, other materials can also be used as raw materials for precision casting. One such material is pure molten glass, which is poured into a mold and solidifies to create a precise replica of the mold geometry. This technique is known as glass molding or glass casting.

Another material used for precision casting is liquid silicone rubber (LSR), which is a rubber-like material that can be poured into a mold and cured to create a solid silicone rubber part. LSR is often used for low-volume production runs or prototypes, as it is relatively expensive compared to traditional metal casting processes.

For precision casting, the selection of the raw materials depends on the desired physical and mechanical properties of the final product, as well as the casting process used. For example, certain alloys may be more suitable for high-temperature applications, while others may be more suitable for low-temperature applications. Similarly, different casting processes may require specific raw materials to achieve optimal results.

Precision casting is a manufacturing process that uses metal alloys and other materials as raw materials to create high-precision metal parts. The selection of raw materials depends on the desired physical and mechanical properties of the final product, as well as the casting process used. Precision casting is a highly versatile and cost-effective manufacturing method that is widely used across various industries to create complex metal parts with consistent quality and performance characteristics.
