Lost foam casting combines the benefits of both investment and traditional sand casting techniques. It utilizes a polystyrene pattern that evaporates upon contact with molten aluminum, leaving an incredibly detailed and smooth finish. This method is gaining traction in various sectors for its simplicity and cost-effectiveness.

Despite its numerous benefits, the production of aluminium stamping parts does not come without challenges. Manufacturers must invest in high-quality dies and precision stamping machines to achieve the desired results. Additionally, working with aluminium necessitates careful handling, as the material can be prone to deformation if not managed correctly during the stamping process.

Green sand is the most commonly used sand in the casting industry. It is a mixture of silica sand, clay, water, and various additives. The term green refers to the state of the sand when it is wet and pliable. Green sand has excellent molding properties, allowing it to hold intricate details and withstand high temperatures during the casting process. Its composition often includes around 10% clay, which helps in binding the sand particles together, providing strength to the mold. This type of sand is primarily used for iron and steel castings and is favored for its cost-effectiveness and availability.
