Functional PVD coatings for tools: drills, mills, threading tools and others
The low coefficient of friction typical of PVD processes support the sliding between the mechanical parts while the high chemical inertia offers a partial resistance to corrosion thus allowing to delay the phenomena of surface damage. This means less downtime due to maintenance, higher productivity and consequently lower production costs. Greater durability of precision components.

PVD treatments for molds and tools
We can manage even small and targeted productions with wear and technical/functional coatings.
Management of even small quantities
We offer solutions for molds, equipment and multiple types of tools with different prerogatives depending on the sector of application of the object, from traditional TiN - CrN - AlTiN - DLC to innovative tribological coatings ideal for HD tools that work in critical conditions such as absence of lubrication, high cutting speeds and surface hardness over 50 HRC.
We have the experience to analyse the typical problems of mechanical or thermal stresses of the various cases using mono-layer or multi-layer coatings with thicknesses from a few hundreds nanometers up to 5µm.
- We can manage even small quantities, small batches of screws and accessories for cutters / cnc, following the processing phases with meticulous care and without omitting the slightest aspect;
- Ad Hoc Customisations made according to your needs.
Corrosion resistance and low friction coefficient
The low coefficient of friction typical of PVD processes support the sliding between the mechanical parts while the high chemical inertia offers a partial resistance to corrosion thus allowing to delay the phenomena of surface damage. This means greater durability of precision components, less downtime due to maintenance, higher productivity and consequently lower production costs.
At high coating temperatures is there a risk of reducing the surface hardness previously obtained with appropriate heat treatments?
Does pre-treatment surface roughness affect the final result?
