Continuous Casting
Self-lubricating graphite dies and mould tubes for continuous casting of copper, brass and bronze alloys.
Graphite solutions for Continuous Casting
Continuous casting of copper, brass, bronze, and aluminium alloys relies on graphite dies and crystallizers to deliver precise cross-sectional profiles with excellent surface quality at high casting speeds. Graphite's self-lubricating properties eliminate the need for external lubricant, while its thermal conductivity and dimensional stability ensure consistent heat extraction and minimal die wear.
Expo supplies horizontal and vertical continuous casting dies, dummy bars, and crystallizer components — machined from premium extruded and isostatic graphite in round, rectangular, hexagonal, and custom profiles — to copper rod mills, brass foundries, and semi-fabricators across India and internationally.
