IPM40 Isostatic Powder Press for Battery Tubes

Fully automatic isostatic powder press for the production of thin-walled tubes made of technical ceramics up to a pressing pressure of 2000 bar.

The press is especially suited to the production of ceramic solid-state electrolyte substrates for sodium-sulfur or sodium-nickel-chloride batteries (ZEBRA batteries).

For increasing its output by adding pressing modules of an identical type, a basic IPM40 pressing module equipped with a robot can be expanded to flexible production cells of up to four units.

The centralized robot, charged with removing the compacts, deals with all pressing modules in alternating sequence while the centralized hydraulic unit and electrical switch cabinet of the production cell open up space-saving layout possibilities best suited to the flow of the material.

Still, each pressing module has its own independent control and visualization system for individual settings and maximum flexibility.

The modular IPM press system is also perfectly suited to thin-walled tubular bodies and long thin rods.
