WASCO water soluble binders for high pressure die casting
WASCO in HPDC process
Innovative WASCO Water-soluble binder systems for HPDC applications
For HPDC applications, Foseco developed a new type of sand core using innovative WASCO water-soluble binder systems and optionally with adaptable coatings to avoid liquid metal penetration into the pores of the sand core. This paper focuses first on some fundamental aspects on the development of such a watersoluble binder system, followed by 2 practical examples, one producing cores for explosionproof instrument housings, and the other manufacturing sand cores for automotive applications.
