摘要： A steam chest mold includes two mold sections defining a mold cavity and a plurality of steam tubes having steam ports positioned within the mold cavity. The mold cavity is closable to contain and compress a plurality of beads such as expanded polyolefin beads. The steam tubes pass through the beads such that steam is injected through the steam ports into the beads to facilitate localized melting and bonding o the bead interfaces to produce a water-impervious panel or billet form. The steam tubes permit bonding of interior beads in thick section billets and panels that cannot be accessed by perimeter steam sources.

摘要： Mutually overlying runs of two endless belts form therebetween a mold channel open at both ends. The mold forming runs move continuously in the same direction at the same rate of speed thereby to draw a sheet of material from a roll thereof downstream into and through the mold channel. The sheet material enters the mold channel in the form of a sleeve charged with only partially expanded granules of a synthetic thermoplastic material containing a heat expanding agent. As the charged sleeve moves downstream through the mold channel steam under pressure is introduced directly into the mold cavity thereby to fully expand the granules and covert the mass thereof into a coherent foamed agglutinated body which takes the shape of the mold cavity.
