Automatic Molding

Automatic Sand Casting for Economical Molding

The Automatic Molding process utilizes one-time-use sand mold. Green Sand is blown into the flasks and tightly packed against both sides of the matchplate. The cope and drag machine flasks are then separated and the matchplate is extracted creating impressions in the sand. The cope and drag flasks are put back together forming a sand mold into which the aluminum is poured. Prior to closing the mold, sand cores can be inserted into the mold to form hollow passageways or to cast intricate geometry that cannot be formed by the matchplate tooling.

Matchplate tooling is a common plate in which the cope pattern is mounted on the upper side, the drag pattern on the underside.
