Abstract
An apparatus and method for the forming of a shaped article includes a means for plasticizing a feed material; a die chamber; a means for delivering a plasticized feed material from the plasticizing means and into the die chamber, the delivery means in flow communication with the plasticizing means and the die chamber; and means for applying a pressure to a material in the die chamber. In operation, a feed material is introduced into a plasticizing source; the plasticized feed material is delivered to a die chamber connectable in flow communication with the plasticizing source; and supplemental pressure is applied to the plasticized feed material within the die chamber.
