Shortened cycle times, reduced energy consumption and distortion-free workpieces: We do not just manufacture products, but also provide intelligent solutions with sustainable benefits for our customers.
We accompany you in finding solutions for your challenges, among other things by means of modern FEM simulation methods. Thanks to our long production experience of complex and demanding products, we are able to provide stable and performant operation of your equipment.
Even if not in person in Cologne at the Hardening Congress, we would still like to present the outstanding material properties of our products and services to you virtually here this year and look forward to meeting you in the live chat!
May we introduce? Our HK Highlights!
Discover our product highlights here:
![]() | Manfred Golling, Senior Technical Marketing Manager, presents here our SIGRATHERM® rigid felt insulation cylinder which is suitable for high-pressure sintering furnaces and consists of several layers of C/C and soft felt. |
![]() | Find out from Andreas Halbmeir, Technical Marketing Engineer, why SIGRATHERM® GFA15 graphite soft felt allows you to use fewer layers of material for furnace insulation - while maintaining the same insulation properties. |
HK Live Chat on October 21 and 22
