Abstract

A manufacturing process for refractory molds for precision casting, characterized in that a wax model or cluster of models is covered with a so-called contact layer, then with a so-called primary layer and, finally, with several so-called reinforcement layers, being each layer consisting of an unclear mass comprising a silicon binder and a refractory product flour, the masses from the contact layer to the reinforcing layers thickening, and a grain refractory product being sprinkled on each layer before it is Dry, increasing the size of the grains from the contact layer to the reinforcement layers, leaving the grains anchored in two successive layers.
