Casting in lost moulds

There are two types of ladle generally used in pouring liquid metal lip and teapot ladles. A third type (i. e. the bottom ladle) is more specific to steel. 

Big moulds are not moved during eooling. The eooling time can be up to several days.

On the moulding side, a basic distinction is made between permanent and lost moulds. Foundries casting in permanent moulds, buy these metal moulds (dies) externally, but typically operate an in-house mould repair and maintenance shop. Foundries casting in lost moulds, often buy wooden, metal or plastic patterns (for their mould design) and operate an in-house pattern maintenance and repair shop. Moulds, cores and lost models are generally produced as part of the foundry process.
