PRESS-CHECK: Quality control for more precision in press hardening

With PRESS-CHECK, you can safely and efficiently monitor both the temperature and the positioning of sheet metal during press hardening. 

Quality control with PRESS-CHECK

  • Automatic sorting of sheets or stopping of the press when limits are exceeded
  • Logging and evaluation of all measured data and disclosure to the master control system via industry-standard interfaces
  • Easy integration of the test system by the flexible structure and variable data customisable interface

Thermography in use in press hardening

Quality Control with PRESS-CHECK from InfraTec

The automated test system PRESS-CHECK works with two powerful high-end thermographic cameras for continuous measurement of two-dimensional temperature distribution. This measurement is carried out before the pressing operation on the surfaces of the boards to be processed and subsequently on the resulting molded parts, ultimately enabling exact compliance with the thermal process parameters.

As a result, you get components with the designed microstructure and a corresponding local resistance distribution. A consistently high production quality is ensured by the thermographic-based, two-dimensional monitoring of process temperatures, 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 recipes. Stampings with different thermal signatures are recognised and can be automatically sorted out, so your wastage rates fall considerably. Furthermore, the software checks whether a sheet is inserted into the press, checks how it is positioned and recognises double sheets. If necessary, the press is stopped automatically. 

PRESS-CHECK evaluation unit

PRESS-CHECK is linked to the higher-level control system of the respective press, and simultaneously transmits data as well as classification of all pressings. With the test software, you can manage the various molds and the associated measurement values automatically, even creating logs. This makes the system 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 systems can be easily integrate in your press processes.
