Advantages and Disadvantages of Lost Foam Casting

CategoryItemDescription
AdvantageComplex Structural CastingsLost foam casting is suitable for complex-shaped structures and single prototype development.
AdvantageHigh PrecisionOffers more accurate dimensions than traditional wood casting. Lost foam tolerance: ±1MM; wood casting: ±10MM (CNS4021).
AdvantageImproved ProductivityPost-processing allows grinding of 10 castings per day—5× more than traditional methods.
DisadvantageBatch Size SensitivityEconomic efficiency improves with larger batch sizes; not ideal for small-scale production.
DisadvantageCasting Material LimitationSuitability declines from gray iron → non-ferrous alloys → carbon steel → ductile iron → low-carbon/alloy steels. Requires preparation to avoid long tuning.
DisadvantageSize LimitationCasting size depends on the capacity of equipment like vibration tables and sandboxes.
