Abstract

Moulding takes place in a mould and core having a fluidified mould material and a core of an elastomeric, plastic type material. The liquid sand mould material consists of 78-85 wt.% sand, 8-12 wt.% aluminous cement, 7-10 wt.% water, 0.03-0.2% of a wetting agent/setting accelerator which comprises 0.05-0.35 wt.% of the aluminous cement and consists of a lithium salt, pref. lithium chloride.
