Rapid sand casting is an advanced version of traditional sand casting, designed to expedite the production of metal parts. The conventional sand casting process involves creating a mold from a mixture of sand and a bonding agent, pouring molten metal into the mold, and allowing it to solidify. In contrast, rapid sand casting leverages advanced technologies such as computer-aided design (CAD), 3D printing, and rapid prototyping techniques to streamline the mold-making process.

The applications of AWJM are extensive. In the aerospace industry, it is used to cut aluminum and titanium components that require high precision without damaging structural integrity. In the automotive sector, AWJM is employed to produce intricate parts and to create window and door glass cuttings.

Moreover, the placement of these pins within the mold is critical. They should be strategically positioned to minimize any potential marks or blemishes on the finished product, often at points where any aesthetic flaws can be least noticeable. The spacing and number of ejector pins utilized also determine how evenly and effectively the casting is released from the mold.
