Abstract

The moulding material is formed into a bed of constant thickness on the upper surface of a conveyor and preferably passes between breadth confining plates. At a stamping station the conveyor is intermittently stopped and a pattern is brought down into the moulding material bed to punch an impression. Blades at the front and rear of the pattern may separate the punched - out moulding from the bed. The binder which is preferably less than 10% by weight of sand may comprise an isocyanate resin or a hydroxyl containing core - oil such as an oil - modified alkyd resin. These may be used with a primary polymer binder. A alkali - metal silicate binder may be employed e.g. with a hardening catalyst. The binder may be heat or gas - hardened but should harden progressively so that the moulding mixture can be brought to a condition in which it may be deformed by pressing but is hard enough to maintain the pressed shape on standing.
