    AMR Graphite Rings 


    AMR graphite rings are made of high purity graphite materials and manufactured by precision CNC equipments to ensure excellent fit. AMR graphite rings are very important parts of the billet casting process. A thin film of oil is distributed through the graphite ring to obtain a smooth surface.
