Casting Tips and Nozzles

CastingTipsAndNozzles NecoR3CastingTips


Casting tips, often referred to as casting nozzles or injectors, determine the width of the aluminium sheet during continuous casting. Casting tip sections, in conjunction with spacers, create a cavity allowing for the flow of metal through the casting tips just before solidification of the sheet.
