Efficiency in Powder Compacting Technology
Nowadays, all PM part manufacturers are subjected to the huge pressure to reduce prices and minimize cost. Apart from the maximum utilization of the machines in multi-shift operation, the manufacturers have to select the optimum machinery in terms of pressing technology. Flat parts, for instance, are produced on mechanical high-speed presses with very high economic efficiency. Here high stroke rates that can be achieved are the focal point. Multi-level complicated components are produced on multiplaten presses providing hydraulic auxiliary movements. Both mechanical automatic presses with modular multiplaten die sets and hydraulic presses with closed-loop controlled movements, equipped with position sensors, are suitable for this application. The geometrical complexity, the requested dimensional tolerances and the density are of decisive influence of the machine to be selected. The sizing is process is carried out on machines providing optical part recognition and automatic part handling. For this wide variety of different applications DORST Technologies can offer customized plants to suit the requirements. To gain maximum economic efficiency, all machines – powder compacting presses or automatic sizing presses – are available with handling systems such as die set change systems, or linkage of the press with the furnace.
