About the EBNER GROUP
The EBNER GROUP, headquartered in Leonding, Austria, is a family business founded in 1948 and a provider of heat treatment, smelting, and casting systems for the steel, aluminum, and non-ferrous metal industries. The group develops, manufactures, installs, and commissions systems such as HICON® hood furnaces, roll furnace, chamber furnace, and vertical blank annealing lines, as well as continuous casting systems. The portfolio also includes turnkey systems for the light metal industry, twin-belt continuous casting systems, as well as casting services and alloy development in the CRC Casthouse (R)Evolution Center in Ranshofen. A dedicated business unit focuses on crystal growth: sapphire single crystals in McSAP ovens and silicon carbide single crystals using the PVT process for the semiconductor, optoelectronics, and power electronics industries. Material-wise, steel, aluminum, copper, and high-strength copper alloys, stainless steel, brass, as well as zinc and lead are processed. Customers come from the steel, aluminum, automotive, and aerospace industries, the semiconductor sector, and renewable energies. Production takes place at locations in Austria, the USA, China, and Mexico.
