Technological Expertise

A portfolio of diversified products

GRANDO processes and markets three complete and separate ranges of polymer-based products (elastomers, cellular materials, thermoplastics) as well as a wide range of composite materials (thermosetting materials, thermoplastics and elastomeric materials), which makes it one of the European leaders in the processing of high-tech materials.

Manufacturing - Ultra-modern and diversified machinery

Thanks to a policy of continuous investment in its machinery and industrial buildings for many years, GRANDO is equipped with numerical control (CNC) machines that are among the best-performing on the market and capable of meeting the most stringent customer requirements.
