The AWB core binder system is based on sodium silicate binders. The
hardening of the cores is done by dehydration, there is no chemical
reaction. This makes the hardening process reversible and reclamation
simple. Dehydration is done by a combination of heated core box, vacuum
and microwave treatment. The binder system has been widely tested at
the University Duisburg – Essen and at the labs of Hydro Aluminium. A
great number of cylinder heads in aluminium gravity die-casting have been
made to prove suitability for serial production.
