a compromise with a sustainable ecosystem

SiOres it's our special thermoplastic exclusive design for work with SiOform1.

Raw material: Resin pellets are melted by the machine itself. The material is kept in a viscous state at 230°C until injection. Solidification happens inside the mold in less than 10 sec.
