ABSTRACT:
A shaped mass of particulate material such as foundry sand, admixed with a polymerizable binder, is instantly completely hardened by contact of gas catalyst therewith. The preferred method and apparatus in accordance with the present invention involves first inducing a vacuum within the shaping space of the shaping element and includes employing means for catalyst gassing of the space within the shaping element rather than of the space within the chamber in which the shaping element resides. In addition, a relatively small "aftervoid" chamber is provided and is connected to the shaping cavity at some location therein which is approximately opposite the location of the gas catalyst inlet. The latter eliminates uncured pockets which tended to result from prior methods and apparatus.
