No false modesty: We at GKN Sinter Metals are at the forefront of trends and innovation. We have a clear vision of what’s to come – and we’d like to share and discuss our points of view, ideas, plans and achievements with you.


Rapid prototyping enabled by Additive Manufacturing, high-density storage of hydrogen in metal hydride tanks: the team at GKN Sinter Metals is bringing game-changing technologies to life. We’ll keep you updated on the latest trends and applications.

Behind the Scenes

People – Products – Processes. We’ll take you behind the scenes of these three main pillars of GKN Sinter Metals and give you insights into our way of creating innovations – always from a very personal perspective.


Dr. Gerd Kotthoff

I want to use this blog as a vehicle to engage the community and drive young engineers’ and decision-makers’ interest in GKN’s technical differentiation of sintered gears. Sharing latest news on our “Design for PM” approaches in an easy and understandable way will help us realize our vision of pushing the envelope for sintered and highly loaded gears.

I’m Gerd Kotthoff, I joined GKN in 2003 and am Director Advanced Gear Technology & Site Director Innovationcenter Radevormwald. My responsibilities include the global development of advanced and innovative gear technologies and products. I am a member of the advisory board of the RWTH Aachen University Laboratory for Machine Tools and Production Engineering (WZL) “Gear Research Circle” and I hold a PhD in mechanical engineering from the University of Aachen as well as seven patents on surface densification and gear rolling, with others currently under review.

I can’t wait to share the exciting potential we have in so many areas – there’s lots to look forward to!

GKN to join Drivetrain discussions at VDI Congress in July

During July 5-6, the international automotive drivetrain community will come together in Bonn, Germany and discuss the latest trends and innovations at the VDI Congress “Drivetrain for Vehicles.”

Are gear wheels becoming obsolete?

I admit that it does sting when colleagues from the digital world call us “traditional machine manufacturers” with well-intentioned regard or “archaic metal smelters” with blatant mockery.
