Challenge & Goal

Embossing dies in tablet production not only have to cope with high quantities, but also transfer the finest engravings, logos or break notches with absolute precision and reproducibility. Typical problems are

  • Abrasion and wear that lead to blurred contours
  • Frequent reworking or replacement of the embossing dies, resulting in costs and downtime.

Our solution

Our DLC coatings (2.0) reliably protect embossing dies against abrasion and adhesion. At the same time, they permanently preserve the microstructures of the engravings, from logos to fine fracture grooves. This achieves consistent tableting tool quality without having to reprocess the punches in between.

Advantages for the customer

  • Consistent quality: engravings, logos and notches remain precise and clean over long service lives
  • Cost reduction: increased service life of the embossing dies significantly reduces tool and process costs
  • Reliable reproducibility: tableting tools comply with regulatory requirements & brand standards
  • Protection of rough, smooth & textured surfaces

  • No limitation of coating thickness for maximum wear protection

  • Avoidance of layer spalling at high pressures

  • Good layer adhesion & biocompatibility
