1. Pattern Creation The process begins with creating a precise wax or thermoplastic pattern of the desired part. This pattern replicates the exact dimensions and features of the final product. The wax pattern can be made using traditional methods or advanced 3D printing technologies.

Casting sand, also known as foundry sand, serves as a mold material where molten metal is poured. The most commonly used type is silica sand, but variations such as olivine sand and zircon sand are also utilized depending on the requirements of the casting project. The effectiveness of foundry sand is evaluated based on its grain size, shape, and thermal stability, which impact the outcome of the casting. Thus, sourcing high-quality sand becomes imperative.

One of the significant advantages of sand casting is its ability to produce large, one-off components as well as small to medium-sized production runs. It is especially favored in industries like automotive, aerospace, and art, where custom parts and prototypes are frequently needed. This adaptability makes sand casting a go-to method for manufacturers looking to streamline the production of complex geometries without the need for expensive tooling.

The current stainless steel precision casting technology has been practically applied in industrial production. At that time, the development of aviation jet engines required the manufacture of heat-resistant alloy parts with complex shapes such as impellers, blades, and nozzles, precise product dimensions, and smooth surfaces.

Green sand iron casting is a widely used method in the metalworking industry, renowned for its efficiency, cost-effectiveness, and versatility. This form of casting involves the use of a mixture of sand, clay, and water, which is called green sand, to create molds for molten iron. The term green refers to the fact that the sand is damp and not yet baked or hardened, distinguishing it from other types of casting processes. This article will explore the various aspects of green sand iron casting, including its composition, advantages, applications, and environmental considerations.
