Concept Laser


Hot-work steel with heat treatment
For the production of components for tool inserts with conformal cooling. These tool inserts can be used for series injection moulding as well as for die-casting. Furthermore the material can also be used for functional components. Tool inserts with conformal cooling. By using a special heat treatment a higher elongation can be achieved. Homogeneous, dense structure.
