Cast is a fundamental manufacturing process and design technique that involves pouring molten material, typically metal, into a mold or cavity to create three-dimensional objects with specific shapes and properties. This ancient yet enduring method, dating back to approximately 3700 BCE, has evolved significantly through technological advancements while maintaining its core principles of transforming liquid materials into solid forms. The process begins with the creation of a pattern, traditionally made from wood, wax, or other materials, which serves as the template for the final object. This pattern is used to form a mold, usually made from sand, plaster, or other heat-resistant materials, into which the molten material is poured. The complexity of cast designs can range from simple geometric shapes to intricate architectural elements and sculptural pieces, making it a versatile technique in industrial design, art, and architecture. The casting process requires careful consideration of material properties, including melting points, cooling rates, and shrinkage factors, all of which influence the final product's quality and structural integrity. Modern casting techniques have incorporated digital technologies, such as computer-aided design (CAD) and 3D printing for pattern making, enabling more precise and complex designs. The process has become particularly significant in sustainable design practices, as it allows for the efficient use of materials and the ability to recycle metal scraps. Cast products and designs are regularly featured in design competitions, including the A' Design Award's Product Design Category, where innovative applications of casting techniques are recognized for their contribution to industrial design excellence.

Cast is a manufacturing process where liquid material, typically molten metal, plastic, or other substances, is poured into a mold cavity that contains a hollow shape of the desired product and allowed to solidify under controlled conditions. This fundamental production technique, dating back to ancient civilizations, has evolved significantly through technological advancements and continues to be a cornerstone of modern manufacturing. The process begins with pattern making, where a replica of the final product is created using materials like wood, metal, or wax, followed by the creation of a mold using materials such as sand, plaster, or metal, depending on the application requirements and production volume. The casting process encompasses various specialized methods, including sand casting, investment casting, die casting, and centrifugal casting, each offering distinct advantages in terms of surface finish, dimensional accuracy, and production efficiency. The versatility of casting enables the creation of complex geometries and internal cavities that would be difficult or impossible to achieve through other manufacturing methods, making it particularly valuable in industries ranging from automotive and aerospace to artistic sculpture and architectural elements. The quality of cast products is influenced by numerous factors, including material properties, mold design, pouring temperature, cooling rate, and post-casting treatments, requiring careful control and expertise to achieve optimal results. This manufacturing method has been recognized in various design competitions, including the A' Design Award's Production and Manufacturing Design Category, where innovative casting techniques and products are evaluated for their technical excellence and creative implementation. The process continues to evolve with the integration of computer-aided design, simulation software, and advanced materials science, enabling more precise control over material properties and final product characteristics.
