Quality Control Of Mould Coatings

Cast irons and copper-nickel alloys are the materials commonly used in the production of moulds and accessories for the glass industry, owing to their excellent thermal conductivity and relatively low cost. However, they are subjected in service to very severe conditions of abrasion and fatigue at high temperature, causing premature wear, deformation or failure of parts, compromising product quality and increasing maintenance costs. In this article the author explains how the correct coating parameters achieved at Intermold can increase the durability of moulds and accessories in glass production.
