HOT-CHAMBER DIECASTING

Diecasting is a common process in the engineering industry. It used to produce many machine components. For some metals with a low melting points, such as zinc alloy. a process called hot-chamber diecasting is used. For example, a carburettor body is produced by this method. There are three main stages in the process. In the first stage the dies are closed. Then the injection plunger is forced downwards and the molten metal is forced in to the dies. Finally, in the third stage, the dies are opened in order to remove the carburettor body
