ABSTRACT:
A process for manufacturing product by using a progressively expanding mold comprises (a) using a stationary piece having a cavity therein and having an opening at one end thereof, (b) assembling a first movable piece in the cavity of the stationary piece, (c) filling a molten material from the opening between the stationary mold and the first movable piece, (d) causing the movable piece to move in an appropriate rate away from the opening for a further increment of the filled molten material between the pieces, (e) solidifying the filled molten material to yield a product, and (f) taking out the product from the stationary and first movable pieces. This invention discloses both a process and an apparatus for positive control of the rate of material solidification of a product and molding a more refined product.
