Casting Processes
Casting Processes are a group of manufacturing techniques where a liquid material (typically metal, plastic, or concrete) is poured into a mold to take the shape of the cavity. After the material solidifies, it is removed from the mold, resulting in a part or product. Here’s a brief explanation of the main casting processes:

- Sand Casting
- One of the most widely used casting methods, it involves creating a mold from a mixture of sand and a binder (like clay or resin). The molten metal is poured into the sand mold, which is then broken away to reveal the cast part. It's ideal for large or low-volume production due to its cost-effectiveness.
- Investment Casting
- Also known as "lost-wax casting," this process involves creating a wax pattern of the desired part, coating it with a ceramic shell, and then heating it to remove the wax. Molten metal is poured into the shell to form the part. This process is used for high-precision, intricate parts, and is common in industries like aerospace and jewelry.
- Die Casting
- In die casting, molten metal is injected into a reusable steel mold (die) under high pressure. This process is ideal for producing small, complex, and high-volume parts with tight tolerances. It's commonly used for parts in the automotive and consumer electronics industries.
- Continuous Casting
- This process is used primarily for metals like steel and aluminum. In continuous casting, molten metal is poured into a water-cooled mold and solidifies as it moves through the mold. The solidified metal is continuously drawn out as a long billet or slab, making it ideal for mass production of long metal sections.
These processes are foundational to the manufacturing of many components, especially when complex shapes, high precision, and cost-efficiency are required.
