Our Story

CRT S.r.l. was established in 1988 as the PVD and CVD coating division of TTN Group, already active for a decade in both steel heat and surface treatments. The challenge was to expand the applications of a technology limited to the cutting tools sector, understanding its huge potentials in several  industrial fields.

CRT therefore became  the first Italian job coater dedicated exclusively to thin film deposition.

Since its foundation, the company has been specialized in niche applications, especially concerning die casting sector, polymeric materials and hot & cold working processes.

The exceptional properties of PVD and CVD coatings can increase the long-lasting of the moulds, preserving its surface finishing throughout the life cycle as well.

The continuous technological innovation, combined with the decision to provide customized solutions to the needs of each customer, has allowed CRT to grow, increasing the number of plants and coatings solutions.

The vocation, gained from the head company T.T.N. SpA , is also to offer thin film coatings on large tools (D max: 1000mm and h max 2800mm), a unique reality in the national panorama.
