Abstract:
Article made of thermoplastic material, which article is rigid and at least partly heat insulating. The article includes a laminate in at least parts of the article. The laminate includes a first and a second layer of solid thermoplastic material (A) and an intermediate layer of expanded thermoplastic material (B) with an average density of 50 - 800 kg/m . The thermoplastic materials (A) and (B) are the same or compatible materials. The article is manufactured according to a process comprising the steps a) forming of a solid outer layer, b) manufacturing of an intermediate expanded layer and c) the appendage of functional parts such as reinforcing profiles, guiding profiles, stacking profiles, hinge parts, pockets, label holders, profiles or holes for automatic handling, locking devices or the like.

Abstract:
Die Erfindung geht aus von einem Anbau- oder Zusatzteil für Haushaltsgeräte, das mit einem Innendruck-Spritzgussverfahren aus Kunststoff gefertigt ist, wobei das Anbau- oder Zusatzteil einen Hohlraum aufweist. Erfindungsgemäß ist der Hohlraum mit einem Stoff gefüllt, dessen spezifisches Gewicht höher als das spezifische Gewicht von Luft ist.
Abstract:
The present invention involves a unitary composite article (10) and method of making same. The unitary composite article (10) comprises a one-piece, plastic body (14) and a stiffening material (26). The one-piece plastic body (14) includes a collapsible first portion having an inner cavity defined by an outer wall formed by an injection molding process. The plastic of the outer wall has a thickness which makes the outer wall susceptible to collapse into the inner cavity during normal usage of the article. The stiffening material (26) substantially fills the inner cavity by an injection process. The stiffening material (26) provides rigidity to the article (10) to prevent collapse of the outer wall into the inner cavity when the plastic body (14) experiences substantial external forces at the first portion during normal usage.
