Abstract

Water-soluble core for compression moulding Al (alloys) Mg, Zn, Pb, Sn alloys, and also plastics, to produce hollow articles, contains anhydrous MgCl2 opt. mixed with Al2O3, Na2CO3, NaCl, MgO, SiO2 and/or Na silicate. Pref. core contains anhydrous MgCl2, 35% Al2O3 30% Na2CO3 40% NaCl 30% MgO and 20% Na silicate all % ages being by weight/weight core. Spec. core contains anhydrous MgCl2, 5-30% Al2O3 and 2-30% Na2CO3 (high strength and smooth surface) or pref. anhydrous MgCl2, 2-35% Al2O3 and 2-20% NaCl.
