TPA50/4S Mechanical axial powder press in high-speed version

Developed and refined systematically over decades and adapted consistently to ever new standards of modern-day industrial production, our TPA50/4S 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 4th generation TPA50/4S 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 TPA50/4S 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.
