摘要

Starting with the shell molding process introduced in the '50's, some of heat cured sand core and molding binder systems which can be applicable to high production foundries were developed. In late '60's, after the first cold box system, the amine cured phenolic urethane binder was developed, number of cold box systems were developed and introduced to the foundry industry. Each system was developed based on different chemistries. Motivations of the development were sand core and mold productivity, reduction of casting defects and environmental pressure. For their different chemistries and concepts of invention, it is important to benchmark the binder systems. In this paper, benchmarking the high production sand core and mold binder systems are conducted in terms of core and sand making property, productivity, casting quality, the cost-in-use and emissions. Furthermore, future visions of high production sand binder systems including both organic and inorganic systems are discussed.
