Chemical And Structural Features Of Cast Iron For The Making Of Moulds For Hollow Glass

Ever-increasing production rates of glass containers create high stresses on moulds. Cast iron still remains the basic material for mould makers. This article illustrates the various types of cast iron available which enable an equilibrium between thermal conductivity on the one hand, and thermal fatigue resistance as well as wear resistance on the other. During the casting process, strict checks are carried out on the chemical composition as well as on the effects of thermal treatment.
