High-Efficiency Vacuum Extrusion Presses for all Kinds of Demands on continuous viscous Forming

Particular robustness, durability and wear resistance are the prominent features of our vacuum extrusion presses, which have been specially developed in terms of both machine design and technical engineering for the extrusion of heavy or very abrasive materials. The presses can be used almost universally, being able to be operated both in horizontal and in vertical position depending on the individual application. Key features include a central vacuum chamber for high material density and modern, frequency-controlled electric drives.

Another standard feature is the possibility to temper the material run very precisely in sections on the feed side as well as on the pressing side in order to achieve high-quality production results with high repeating accuracy.

Changeable extrusion worms of various geometric shapes, cylindrical or conical designs and a whole range of useful additional equipment result in a high degree of flexibility and adaptation to the individual demands and requirements.

A modern, network-capable process control system is used for visualization, operation and the evaluation of all process data.
