The appropriate draft angle can vary depending on several factors, including the type of metal being cast, the complexity of the part, and the design specifications. However, as a general guideline, draft angles typically range from 1° to 5°. For deeper features or more intricate designs, draft angles of up to 7° or more may be considered.

1. Cost-Effectiveness One of the most significant advantages of sand casting is its lower cost compared to other casting methods, especially for small production runs. The materials used are inexpensive, and the process can be carried out with minimal equipment.

The addition of water requires careful monitoring, as ideal moisture content usually falls between 2-4%. The mixture is combined using a mechanically controlled mixer to ensure an even distribution of the components. After mixing, the green sand should have a ‘moist’ feel yet be cohesive enough to hold its shape when squeezed in hand. The consistency can be tested by forming small balls; they should hold together without crumbling or falling apart.

As industries move towards more sustainable practices, the environmental impact of sand mining has come under scrutiny. The demand for casting sand can lead to ecological damage, making recycling foundry sands an increasingly important consideration. Reusing sand can mitigate environmental damage while also reducing costs in the casting process.
