Abstract:

In addition to clay minerals, which have been used for decades as binders for the compaction moulding process (with bentonite moulding materials), there are also inorganic chemically curing binder systems of long-standing tradition in the foundry.

Since the 1940s, cement has been used for mould and core production. The core production was then revolutionized in the 1950s by the water glass CO2 process. Since that time, the classical inorganic systems have superseded the organic binder systems, with notable increase around the 1970s and 80s.

Due to a constantly increasing environmental awareness in the foundry industry, the almost forgotten inorganic binder systems have had a renaissance at the turn of this century. While there seems to be some conflicting information surrounding the current state of the application, as well as its achievable property level, the aim of Inorganic Binders for Mould and Core Production in the Foundry is to provide answers to the question of what can afford inorganic binder systems at the present. On the other hand, this book should open questions or problems to be solved in order to increase the proportions of mould and core production in the coming years.
