DUMATIC® Coating
DUMATIC® – titanium carbide – Highest levels of hardness and abrasion resistance for forming applications
Coating structure
This coating combines the advantages of Duplex-TiCN and FORMATIC®. The new DUMATIC® coating is always manufactured as a Duplex version, therefore with a plasma diffusion process of the base material. DUMATIC® is a structured multi-layer design with high content of TiC (approx. 4000 HV! ). The uppermost layer is developed as slide-favorable and colored sealing coat.

The dies and punches used in stamping, forming, and blanking operations can greatly benefit from the DUMATIC® coating. This coating provides superior wear resistance and a significant reduction in material adhesion throughout the process. With tools coated with DUMATIC®, customers experience the following benefits:
Benefits of using DUMATIC®:
- Increased tool durability: The DUMATIC® coating improves the wear resistance of dies and punches, extending their lifespan and reducing the need for frequent replacement.
- Reduced downtime: By reducing material adhesion and abrasion, DUMATIC® helps prevent blockages and jams during the stamping and forming process, resulting in less machinery downtime and increased operational efficiency.
- Improved product quality: The reduction in material adhesion provided by DUMATIC® contributes to greater precision and consistency in stamped and formed parts, resulting in higher-quality end products with fewer defects.
Due to its relatively low oxidation stability, DUMATIC® is not suitable for high-temperature applications.
