TPA70S Mechanical axial powder press in high-speed version

Being part of our series of mechanical high-efficiency presses, our TPA70S is a state-of-the-art press of highest reliability and performance. A wide range of accessories and equipment variants enables the customer to configure even a mechanical press according to his individual requirements.

Our TPA70S is compatible with all mechanical DORST tool die sets of the previous models and the earlier machine types TPAn40 and TPA45.

The S version features a specially adapted curve characteristic and reduced travels. The significant increase in output thus achieved but also its high running smoothness and a well-balanced, gentle compression curve make this press a very attractive solution.

When it comes to machine setup and continuous process monitoring, the operator will be assisted by our latest network-capable DORST Press and Quality Controller (PQC) with graphical visualization system. In addition to programming and visualizing the pressing curves, the PQC offers a large range of other functions relating to tool protection, automatic filling height adjustment and production statistics.

In its standard version, our TPA70S is equipped with a servo-motorized filler in conjunction with a latest-generation PQC, the dynamically controlled filler axis being integrated seamlessly into the mechanical constrained pressing sequence. The servo-motorized filler combines the advantages of a freely programmable axis with the benefits of a mechanical press, making adjusting the filler characteristic and optimizing process times as easy as can be, even with a mechanical press. The servo-motorized filler is very wear-resistant and contributes significantly to increasing the performance of the press.
