The use of PVD coatings in these types of applications, both hot and cold, is necessary as they help to combat abrasion and adhesion of the work material on the tools.
The main properties of the coatings, focused on this type of applications, are hardness, without losing toughness, which helps to increase wear resistance and minimum friction coefficients that help the material to flow, delaying the appearance of seizure (adhesion).
In Metal Estalki we not only apply a quality coating, but we also enhance it by adapting it to the productive needs of the user, accompanying it with the following solutions:
Surface preparation service
Tool surface optimization service. Improves tribological properties by reducing friction.
Duplex Process
Ionic nitriding improves adhesion of the coating to the substrate.
Preparation focused on fine cutting tools, improves the surface quality of the substrate without damaging the cutting edges.
Hard coatings finished in DLC
Anti-adhesive layer, made of DLC, which helps to prevent the appearance of adhesions generated by lack of lubrication during the production process or by materials with adhesion tendency.
