Gravity Casting: Reliable Gravity Casting from Huaxiao
Gravity Casting (permanent mold) lets molten metal fill a reusable metal mold by gravity—balancing cost, quality, and volume between sand and high-pressure die casting.
How Gravity Casting Works
Molten metal is poured into a coated steel mold and solidifies under gravity; the mold opens to release a denser, finer-grained casting than sand allows.
Gravity vs. Die Casting
Gravity (permanent mold) costs less in tooling and handles larger parts; high-pressure die casting is faster for very high volume.
Materials
- Aluminum—wheels and housings
- Brass and bronze—plumbing
- Cast iron—select parts
Industries
Automotive, plumbing, and machinery use gravity casting.
How to Spec Your Gravity Casting Job
- Define alloy and grade.
- Give the part and tolerances.
- Note wall and draft.
- Set finish and machining.
- State quantity and cadence.
FAQ
When choose gravity casting?
Mid-volume parts needing density and finish without die-cast tool cost.
Better than sand?
Yes—denser, smoother, more repeatable.
