Optimal press results
The HERZOG HP-P series pellet press is the basis for the preparation of stable pressed pellets. It offers the properties which are crucial for achieving the desired uniformity and density in each individual pressed pellet. The design of the equipment and variability of the pressing parameters ensure uniform optimal quality of pressed pellets from all ground materials.

Avoidance of contamination
In the standard version of the press, the counter pressure plate of the die is cleaned with a brush which rotates in alternate directions. A second press tool can be built in to prevent cross contamination between two different sample types.

Program-controlled pelletizing for high reproducibility and throughput
All the parameters which are important for the pellet pressing process such as total pressing force, incremental increase of the pressing force and pressure holding time can be preset.
They are controlled directly, reliably and continuously via a program. Errors caused by incorrect handling or adjustment are now a thing of the past. Access to the program parameters is only possible using a password.

Designed for automation
The hardware and software design of the HP-P has been optimized for the seamless integration into automation. The small front face makes the HP-P especially suitable for fitting in robot automation. Even a subsequent integration of the HP-P into an automatic system is possible without any problems.
