Green sand is primarily composed of silica (sand), clay, water, and other additives. The silica provides strength and resistance to high temperatures, while the clay serves as a binding agent, helping to retain the shape of the mold. Water is added to increase the cohesiveness of the mixture, allowing it to easily form around the desired pattern.

5. Sustainability Practices With increasing emphasis on sustainability, consider manufacturers that implement environmentally friendly practices in their production processes.

4. Guide Pins and Bushings To maintain alignment between the punch and die, guide pins and bushings are employed. They ensure that the punching action is precise and that the components remain aligned during operation. This alignment is critical for achieving high-quality finished products.
