1. Cost-Effectiveness One of the primary advantages of aluminum green sand casting is its affordability. The materials used (sand, clay, and water) are readily available and inexpensive, making it a viable option for both large-scale production and small batch runs. Moreover, the reusable nature of green sand further reduces costs.

1. Mold Preparation First, the die or mold is created from steel or iron, designed to the specifications of the part. The mold is treated to withstand high temperatures and pressures.

2. Versatility Green sand casting can accommodate a wide range of aluminum alloys, which allows manufacturers to tailor their products to meet specific performance and strength requirements. This adaptability makes it suitable for producing various shapes, sizes, and weights, from intricate designs to larger components.

2. Mold Design The design and construction of the mold can affect how the molten metal interacts with the sand. Well-designed molds with appropriate draft angles help reduce friction, contributing to a better surface finish.
