The World Money Fair: vacuum furnaces for the minting industry

Held between 29-31 January 2020 in Berlin, Germany, the World Money Fair gathered together thousands of coin collecting enthusiasts, metal working businesses, and we were there.

Much more than just a jamboree for hobbyists, the WMF is a major trade event, where deals are done and ideas are shared.
As part of the packed program of guest speakers, we had the chance to explain how vacuum heat treatment works, and how it applies to coin production. And we really made an impression.

In this article, we'll look at the WMF itself, and offer some insights from the TAV VACUUM FURNACES team that should be relevant for anyone in the minting industry.

Learn all about coating the additive manufactured Titanium64 #2

In the previous article we’ve seen how AlTiN thin film deposition process was carried out via reactive Physical Vapor Deposition High-Power Impulse Magnetron Sputtering (PVD HiPIMS) to coat Ti6Al4V substrates, realized via Selective Laser Melting (SLM).
Two different SLM process conditions were employed for modifying the obtained part surface morphology and, later, the samples were heat-treated under high vacuum.

Do not miss this in-depth investigation and the conclusions at the end, we’ll provide you all the information to get the most out of these three technologies.

Learn all about coating the additive manufactured Titanium64 #1

Among the industrial AM technologies, selective laser melting (SLM) is the most widespread, thanks to its process stability and its favorable ratio between costs and part quality. However, selective laser melted products require coatings for functionalizing the surface with extra properties and in this article we’ll see how thin film deposition process can be carried out to coat titanium substrates.

Is it possible to coat the titanium alloy substrates to obtain a good improvement of the mechanical surface features?
What’s the role of vacuum heat treatments on additive manufactured parts?
Can the laser scanning paths affect the resulting adhesion of the coatings?
