Key Differences Between Sand Casting and Die Casting

Both sand casting and die casting shape molten metal — but they serve very different applications. Choosing the right method depends on volume, precision, and part complexity.

⚙ Sand Casting:

• Uses a disposable sand mold for each part

• Suitable for low to medium volume production

• Flexible for large or complex shapes

• Typically rougher surface finish (Ra ~6–25 µm)

• Looser tolerances (unless machined afterward)

• Lower tooling cost, but slower cycle times

  
  

⚙ Die Casting:

• Uses a permanent steel die that can produce thousands of parts

• Ideal for high volume, consistent production

• Produces fine detail and thinner walls

• Smoother as-cast finish (Ra ~1–3 µm)

• Tighter tolerances

• Higher tooling cost, but faster cycle times

  
  

💡 Where LVIO adds value:

LVIO Precision focuses on managing die cast parts where consistency, fine detail, and secondary machining are required.

We assist customers who may be shifting from sand to die casting for better repeatability or part consolidation — managing the casting vendor, machining, finishing, and assembly all under one roof.
