dummy bar

Metal is poured into the mould and withdrawn with the dummy bar once it solidifies.

Starting a continuous casting machine involves placing a dummy bar (essentially a curved metal beam) up through the spray chamber to close off the base of the mould.

Cotton overbraids are commonly used for Concaster Dummy Bar seals where the overbraid is sacrificial and burns off in use to release the core without leaving a deposit.

The starter bar, also called a dummy bar, has a free end portion which is flexible for storage and a substantially rigid portion at the end which plugs the mold.
