Powdered high-performance materials are the indispensable starting point for a variety of functional and structural components for new and future-oriented solutions in vehicle technology, drives, communication technology, the generation, distribution and storage of electrical energy, and for the development of network infrastructure and charging technology. Modern lighting systems, sensors, control systems, controls and mobile entertainment electronics are already largely based on components that are manufactured using powder molding methods.
The art lies in shaping a powdery material into an industrial component so that either the special functional properties of the material, e.g. magnetism, ion conductivity, or the structural properties of the component, e.g. temperature resistance, wear resistance, acid resistance, are optimal in later use come into play.
Above all, axial powder pressing in all its variations should be mentioned. The advantages of this production method lie, on the one hand, in the possibilities of near-net-shape shaping and, on the other hand, in the high cost-effectiveness through a targeted use of materials with high possible unit outputs. Where axial powder pressing is not necessarily the most practical, other and related pressing processes such as extrusion of plastic masses, isostatic dry pressing and also pressure casting of water-based suspensions are used. The pressed components usually achieve their maximum strength and final properties through the subsequent heat treatment, known as sintering.
Compared to other metal processing primary forming processes and the commonly used metal-cutting forming processes such as turning, milling and drilling, powder forming occupies a niche in production technology. The ongoing development of increasingly high-performance materials and the question of how to process them for practical applications, especially for applications related to the energy and mobility transition, is increasingly bringing this production technology into focus. Powder shaping is constantly developing into an indispensable key technology for innovative markets and future industries.
DORST TECHNOLOGIES, based in the south of Munich, Germany, is a leading international provider of machines and complete production systems for the ceramic and powder metallurgy industries with local support in all industrialized countries.
