Quartz sands and resin sands solutions

Casting is a productive process used in the manufacturing of automobile engine blocks, agricultural parts, pipe fittings, mining parts, railway parts, wind power parts, that is, any type of casting.

For this market, Jundu offers solutions in Quartz Sands (base sand) and Resinated Sands (Shell Molding process). The differential elements in its specification are grain purity, low levels of fines, high sphericity and roundness of the grains, and pH close to neutral.


This set of attributes provides stability and advantages in the manufacturing process of the molds and cores used in the casting of the parts:

  • Increased outflow of gases, during the casting of the parts.
  • Better mechanical recovery of molds and cores.
  • Less mold expansion at high temperatures.
  • Versatility during the manufacturing of molds and cores.
  • Reduction of casting costs.
