Beschreibung
Zusammenfassung:	Process is disclosed wherein plastic material is passed into a mold cavity; pressurizing fluid is injected into the plastic material under controlled pressure and at a controlled rate to cause the plastic material to flow out and assume the contour of the cavity, the gas pressure being maintained until the plastic material is self-supporting. The resulting article has an outer skin and a generally hollow center containing skin-connecting structural "webs".
