FAQ - Foire aux questions

Sand casting is a traditional metal casting process in which molten metal is poured into a sand mold cavity. It is widely used for producing large, complex, or low-volume metal components.
Sand casting is compatible with a wide range of metals, including gray iron, ductile iron, acier au carbone, aluminum alloyset brass. The choice depends on the application and required properties.
  • Cost-effective for small to medium production runs
  • Handles large and complex shapes
  • Wide range of metal options
  • Short lead time for prototype or custom parts
Common sand casting methods include:
  • Coulée de sable vert
  • Moulage au sable de la résine
  • Sodium Silicate Casting
  • Moulage en coquille
Each has specific advantages depending on precision, surface finish, and production scale.
Yes. Sand castings are often machined to achieve tighter tolerances. Common surface treatments include:
  • Shot blasting or sand blasting
  • Anti-rust coating or painting
  • Galvanizing or heat treatment
Quality is ensured by:
  • Optimizing mold design and gating system
  • Controlling sand quality and compaction
  • Monitoring pouring temperature and speed
  • Applying visual and non-destructive testing (e.g. UT, X-ray)
