Thermography in Use in Press Hardening and Hot Forming

Quality Control with PRESS-CHECK from InfraTec

The automated test system PRESS-CHECK works with two or more powerful high-resolution infrared cameras for continuous measurement of the two-dimensional temperature distribution on the parts before and after the hot forming or hot press stamping process, ultimately enabling full compliance with the specified thermal process parameters.

As a result, you manufacture parts with the designed microstructure and a corresponding local hardness distribution. The thermographic-based, two-dimensional monitoring of process temperatures during the hot forming or hot press stamping process ensures a consistently high production quality, with distinct advantages over merely selective temperature measurements on reference points offered by pyrometers, for example.

The process-specific temperature limits for the differently shaped metal parts can be managed in special parameter sets, also called recipes. Stampings with different thermal signatures during the hot forming process are recognised and can be automatically sorted out, so your wastage rates fall considerably. Furthermore, the system checks whether the sheets are placed into the press in the expected number and correct position. In doing so, it can also detect blanks that are incorrectly placed on top of each other (double sheets). If necessary, the press can be stopped automatically, e.g. to avoid expensive damage to the tools.

PRESS-CHECK is linked to the supervisory control system of the respective press, and transmits data as well as the classification of all pressings in real time, thus avoiding slowing down of the hot forming process. With InfraTec´s PRESS-CHECK you can manage the various molds and associated parameter sets automatically, even creating logs. This makes InfraTec PRESS-CHECK universally usable for all applications running on the press without the need for additional equipment and setup time. With highly reliable components, special protective housings, a flexible design and industry-standard data interfaces, the PRESS-CHECK test system can be easily integrated in your press processes.

Why Monitor the Process of Press Hardening?

Automotive low weight components demand a precise microstructure and corresponding local strength distribution. Good reasons to monitor the process of press hardening by the use of infrared cameras.

Thermography in Use in Press Hardening

The automated test system PRESS-CHECK from InfraTec serves to control the production process during press hardening. It is equipped with several infrared cameras, which monitor the furnace exit, the moment before and after pressing as well as the cooling of the pressed parts. Thus, a complete temperature measurement and position monitoring is easily possible - high-level quality control due to thermography.
