Leghe di zama | Le leghe

We are able, throughthe great expertise gained, to operate in refining and processing materials containing a significant contribution of zinc: all zamak bars in line with the European standards EN 1774.
We make use of a spectrometer, checking all different and various production stages, to provide all our products with top quality standards.

The advantages

Advantages of Zamak die-casting processing:

+ Enhancement of materials

+ The trust of die-casting companies on the use of a top quality product only

+ Competitive prices compared to competitors

+ Manufacturing and product delivery speed

+ Zamak alloys quality
