Ingot Casting ManufactureManufacturing Process
Ingot manufacture however can produce very large raw form castings and requires much less manufacturing complication than continuous casting. Ingots are commonly round square or rectangular in shape. Each ingot constitutes a certain amount of metal. Numbers of ingots of know mass may be used to quantify material requirements.
