Metal casting
Expendable mold casting is a generic classification that includes sand, plastic, shell, plaster, and investment (lost-wax technique) moldings. This method of mold casting involves the use of temporary, non-reusable molds. Sand casting is one of the most popular and simplest types of casting, and has been used for centuries. Sand casting allows for smaller batches than permanIn casting, a pattern is a replica of the object to be cast, used to form the sand mould cavity into which molten metal is poured during the casting process.

Everything you need to know about metal casting
Metal casting, a metalworking process involving liquid metal and a mold, has existed for thousands of years. Over its history, metal casting has been used to make everything from swords to wind turbines, and today it is one of the most valuable and versatile methods for making high-quality metal parts. This guide looks at the basics of The “pattern” is essentially a replica of the object about to be cast. Usually made out of wood, metal or model board, patterns are used to create cavities in moulds. It is through pouring molten metal into these moulds that aluminium castings are created. Many factors have to be taken into consideration when designing a pattern to ensureFoundry Pattern Making & Capabilities Harrison Castings Ltd
