摘要： The invention relates to a method for producing a molding by means of the following steps: producing a molding compound, plasticizing the molding compound in an extruder and removing it via a slotted nozzle, feeding the green product into a planishing mill, smoothing the green product by at least one planishing process, chemical and/or thermal debindering and sintering. The continuously operating method enables a cost-efficient production of preferably flat products having a high surface quality.

摘要： The invention relates to a method for producing highly porous sintered parts, according to which free-flowing thermoplastic moulding materials are expanded at a temperature ranging between 80 and 130 °C. Said method is essentially characterised by the use of expandable polystyrene as the expanding agent, in addition to corresponding binding agents. During the expansion process, encapsulated cellular polystyrene foam particles are formed, allowing the production of mechanically solid sintered bodies with a percentage volume of pores of 85 % and a uniform pore diameter. The method is used to produce open- or closed-pore ceramic and/or metallic sintered bodies.

摘要： The invention relates to a method for producing highly porous powder-molded bodies made of ceramic and/or metallic matrix material by post-foaming swellable polystyrol particles that are provided with a layer of essentially matrix powder and polyamide as an organic binder component. Porous molded bodies having a honeycomb-type cellular structure and densely sintered, highly supportive cell walls are obtained by controlling post-foaming in the inventive manner in a closed molding device.
