Coatings for hot forging and die-casting


Molds and tools used in the hot forming of metal parts are subjected to heavy stress during their use.
Our solutions are designed to respond to the critical issues in your industry, namely adhesive wear, abrasive wear, thermal fatigue and chemical aggression.

We provide you with advanced technologies, with which you can obtain decisive results:

Increased resistance to abrasive and adhesive wear

generated by cast alloys such as aluminum, zamak, bronze and brass. The anti-adhesive capacity of our treatments avoids or significantly delays the metallization of the molding parts and protects the most critical and fragile or most exposed areas of the mold.

Increased resistance to thermal fatigue

generated by the alternation of low and high temperatures (thermal shocks). Our coatings limit thermal phenomena in under-pouring areas and delay the development of cracking and adhesion of the casting to the surface of the mold, reducing significantly the risk of breakage.

Increased resistance to corrosion

produced by oxygen at high temperatures and catalysed by release agents. The chemical stability of our coatings offers tremendous corrosion protection.

Increased resistance to compression

generated by the high pressures involved thanks to the high hardness layer.

Lower friction coefficient (COF)

which favors the filling of the mold.

Improvement of the alloy distribution

Our solutions improve the distribution of the alloy within the mold, reducing filling times and postponing the usual cleaning operations of the mold.

Increase of mold lifecycle and reduction of maintenance costs

The use of the suitable coating contributes to a considerable increase in the service life of the molds as well as to a reduction in machine downtime and a containment of cleaning and maintenance costs.

Green technology

Our coatings are deposited using a vacuum technique. Reagents and waste products have no environmental impact. As a result, our PVD technology is truly green.

Maximum performance and productivity are achieved through the optimization of the entire processing cycle.

Nitriding and polishing are two accessory processes that can further improve the abrasion resistance and adhesion characteristics of the system.

Ion nitriding

Nitriding, by means of nitrogen diffusion, generates enriched layers that increase wear resistance, surface hardness (700HV) and resistance to thermal fatigue.

Polishing

Pre-treatment polishing or lapping is often essential to further reduce the adhesive phenomena of metallization, favor the distribution of the alloy in the presence of deep cavities, improve the most stressed areas or restore a glossy finish on the mold by improving the aesthetics of the detail. By relying on our specialized department, you can count on high quality standardized processes to obtain optimal surface roughness values ​​(Ra).
