Repeatable Production
Permanent moulds support consistent geometry and stable production quality across repeated batches.
Gravity Die Casting for Durable Non-Ferrous Industrial Components
EDS supports gravity die casting projects for aluminium, bronze and other non-ferrous components where dimensional repeatability, surface quality, tooling strategy and reliable supplier coordination matter.
Process Overview
A permanent mould casting route for repeatable non-ferrous components
Gravity die casting uses a reusable metal mould, normally made from steel or cast iron, to produce non-ferrous metal components. Molten metal is poured into the die cavity under gravity, where it solidifies into a controlled and repeatable component shape.
Compared with conventional sand casting, gravity die casting can provide improved dimensional stability, better surface finish and more repeatable production quality. It is often used when the project volume justifies permanent tooling and the component requires consistent geometry over time.
EDS helps customers evaluate gravity die casting feasibility by reviewing alloy selection, part geometry, tooling investment, wall thickness, cores, machining allowance, inspection requirements and supplier capability.
Good Surface Quality
Gravity die casting can provide cleaner surfaces than many conventional sand casting routes.
Tooling Efficiency
Reusable dies can support cost-effective production when volumes justify the tooling investment.
Process Advantages
Why gravity die casting is selected for stable industrial production
Gravity die casting is often selected when a component requires better repeatability than sand casting and does not require the speed or pressure-driven filling of high-pressure die casting. It provides a strong balance between tooling life, dimensional control, mechanical performance and production stability.
Dimensional repeatability
A permanent metal die provides a stable mould cavity, helping maintain consistent component geometry across production runs.
Improved mechanical properties
Controlled solidification in a metal mould can support better density and mechanical behavior compared with some sand casting alternatives.
Reduced finishing effort
Better as-cast surface quality and dimensional control can reduce downstream finishing and machining effort in suitable applications.
Industrial Applications
Gravity die cast components for mechanical, hydraulic and industrial assemblies
Gravity die casting is widely used for non-ferrous parts where strength, dimensional stability and repeatability are important. Typical applications include housings, covers, pump bodies, valve parts, hydraulic and pneumatic components, brackets, gear casings, machine parts and marine hardware.
The process can be especially useful for aluminium and bronze components that require controlled production, reliable surface quality and additional machining or finishing operations before final use.
Technical Review
Key decisions before starting a gravity die casting project
Gravity die casting requires a careful balance between component design, material behavior, die design, expected production volume and final machining requirements. EDS supports this review before quotation, supplier selection and production follow-up.
| Alloy selection | Review of aluminium, bronze or other non-ferrous alloy requirements according to strength, wear, corrosion and operating conditions. |
|---|---|
| Die design and tooling | Evaluation of mould design, parting line, ejector strategy, expected die life and tooling cost against production volume. |
| Wall thickness and feeding | Assessment of wall transitions, solidification behavior, feeding strategy and risks related to shrinkage or porosity. |
| Cores and internal features | Review of sand or metal core requirements for internal cavities, passages and functional features. |
| Machining and inspection | Definition of machining allowance, critical dimensions, dimensional reports and inspection documentation requirements. |

Supplier communication
Follow-up with production partners during tooling, casting, machining, finishing and delivery.
Process Comparison
When gravity die casting may be preferred over other casting routes
Gravity die casting is often chosen when repeatability and surface quality are important, but the part does not require high-pressure die casting or the project material, geometry or volume makes other routes less suitable.
Compared with sand casting
Gravity die casting can offer better surface finish, dimensional repeatability and production stability, while sand casting may remain more flexible for very large or lower-volume components.
Compared with high-pressure die casting
Gravity die casting can be more suitable for thicker sections and selected non-ferrous parts, while high-pressure die casting is often used for high-volume thin-walled components.
Compared with investment casting
Gravity die casting can be efficient for repeatable non-ferrous components, while investment casting is often preferred for finer detail, thinner walls and broader steel alloy options.
