The application of functional PVD allows to improve the surfaces' finish, increase their resistance and prolong their life cycle, avoiding waste and consequent faults. These coatings reduce the article's grip, allowing higher cadence and less time the equipment spends stopped.
In terms of cutting tools it takes place a significant increase in durability and resistance to punctures and matrices. Even in the area of plastic and rubber mouldings and mouldings for injection casting of non-iron metals (aluminium and zamak), this type of coating allows to reduce wear and tear and corrosion, improve de-moulding and facilitate the cleaning process.
PVD coatings can be applied to most metals, ceramic surfaces and some plastic materials.
