World Money Fair Technical Forum Review: Part 2

In last month’s issue of Coin & Mint News, we covered five of the presentations made in the first session of the World Money Fair Technical Forum 2023, which took place on 2 February in Berlin and was hosted by Dieter Merkle of Schuler and Thomas Hogenkamp of Spaleck.

In this issue, we cover the five presentations made in the second session, which focused on PVD coating and toolmaking.

The remaining presentations from the third session will be covered in the next issue.

Teer Coatings

Dr Halin Sun, Technical Director of Teer Coatings, introduced his topic by thanking the Royal Canadian Mint for their cooperation in developing PVD coatings for the mint industry from as far back as 2002. He listed the six PVD coatings currently used in the numismatic industry, the latest of which is a carbon, or more specifically, a graphite coating.
