Abstract
Production of quasi-endless profiles comprises pressing metallic and/or ceramic powder with a binder (mixture) at a temperature and pressure, at which the binder mixture has low viscosity, as flowable mixture with a screw extruder through a nozzle and adjusting the binder amount so that the rod produced from the nozzle is inherently stable. The profiled rod is then sintered. USE - As electronic components, filter tubes, high temperature heat exchanger tubes, saw blades for metal processing, welding electrodes and catalyst carriers. ADVANTAGE - The binder can be easily removed from the rod.
