Patent application numberDescriptionPublished
20100101454Method and Device for Introducing Additive Materials - The invention relates to a method and a device for introducing and/or adding non-dry-powder additive materials and/or coating materials with a liquid, solid, semi-solid, or paste-like consistency or in suspended or emulsified form, for example, peroxides, fats, waxes, IV improvers, polymers, or similar materials, to an existing lumpy or particulate material which is moved and mixed, and optionally warmed and reduced to small pieces in a receptacle and/or compressor (04-29-2010
20100216902Method for the pretreatment, reprocessing or recycling of thermoplastic material - The invention relates to a method for the pretreatment, reprocessing or recycling of thermoplastic material, wherein the plastic material to be treated is heated in at least one receptacle or reactor while undergoing constant mixing or movement and/or comminution at a temperature below the melting temperature of the plastic material, and as a result is at the same time crystallized, dried and/or purified, wherein at least one rotatable comminuting or mixing tool, with working edges that act on the material with a comminuting and/or mixing effect, is used for the mixing and/or heating of the plastic material, the heating taking place in particular by applying mechanical energy.08-26-2010
20100289175Procedure for Extrusion of Plastic Material and Extruder - The invention relates to a method for extruding plastic material using a screw-type extruder (S), wherein a first pressure (P11-18-2010
20110040011Process for Producing a Filled Polymer Material - The invention relates to a method for producing a thermoplastic polymer material that is filled with at least one filler, preferably calcium carbonate CaCO02-17-2011
20110049763Method and Device for Injection Molding Plastic Material - The present invention relates to a method and to a device for injection molding plastic material, wherein the starting plastic material to be treated is first subjected to a pretreatment, wherein the plastic material is heated in a receiving container at a temperature below the melting temperature while constantly being mixed, and thereby at the same time is crystallized, dried and/or cleaned and/or the intrinsic viscosity thereof is increased. According to the invention, the plastic material pretreated in this way is transferred into a screw injection molding machine (03-03-2011
20110251368Method and apparatus for processing of plastic material - The invention relates to an apparatus and a method for the processing of plastic material, with a receptacle or cutter-compactor (10-13-2011
20110287123Apparatus for granulating hot cut - The invention relates to an apparatus for granulating hot cut, in particular thermoplastic resin material, the material strands melted by an extruder being knocked off into granule pellets in a granulating housing (11-24-2011
20120024999Rotor Disk - The invention relates to a rotor disk (02-02-2012
