The invention refers to moulding systems used e.g. in moulding preexpanded plastic foam particles which are welded or sintered to a homogeneous mass by introduction of heating media and then cooled for removal. The walsl of the mould are arranged in such a manner that e.g. steam reaches into the mould throu wall perforations but the cooling water is contained by another wall. The chambers are formed by flat panels and suitable spacers and inlet nozzles are provided. |
