In-process temperature monitoring of the press hardening process offered by AP&T

In-line process monitoring for press hardening is now offered by AP&T offering higher and more consistent quality of formed vehicle parts, shorter cycle times and better control over the entire manufacturing process.

To ensure that the finished vehicle part delivers the desired material properties, it is crucial that the blank is heated up, formed and cooled down at exactly the right temperatures.

AP&T’s solution sees Pyrometers and infrared cameras used to measure the material’s temperature both before and after pressing. The pyrometer registers the absolute temperature at a certain point, while the infrared cameras are used to read the heat distribution on the part’s surface. All of this takes place without any of the equipment coming into physical contact with the material.

“Our monitoring equipment enables our customers to achieve an optimised and well-controlled process that gives the end product a higher level of quality,” says AP&T project leader, technology development Jörgen Theander.
