Gravity Die Casting
Strong Parts, Consistent Quality
The reliable middle ground between sand and high-pressure casting. Magnus Sourcing has access to India's gravity die casting foundries, pouring molten aluminium into reusable steel moulds to produce dense, fine-grained parts with excellent finish and repeatability - delivered reliably to your facility, wherever you operate.
Gravity Die Cast
Process
Mould Preparation
The reusable steel die is cleaned, coated with a refractory wash and preheated - ready to produce consistent parts cycle after cycle.
Core Setting
Sand or metal cores are placed into the die to form internal cavities and hollow sections, enabling complex internal shapes.
Metal Pouring
Molten aluminium is poured into the die under gravity alone - no injection pressure - for a smooth, controlled fill.
Filling & Solidification
The metal fills the cavity and solidifies against the cool steel die, producing a fine grain structure and good mechanical strength.
Die Opening & Ejection
Once solidified, the die opens and the casting is removed cleanly - ready for the next cycle.
Trimming & Finishing
Gates and risers are removed, then parts are fettled, heat-treated where needed and inspected before dispatch.
Why Engineers Choose
Gravity Die Casting?
Stronger Than Sand Castings
Pouring into a metal die gives a finer grain and denser structure than sand casting - better mechanical properties and pressure tightness.
Great Finish & Repeatability
Reusable steel moulds deliver smooth surfaces and consistent dimensions across every part - ideal for medium-to-high volumes.
Cost-Effective Quality
Lower tooling cost than high-pressure die casting, with higher quality than sand - the smart choice for mid-volume aluminium parts.
