Casting Aluminum Molds
Die casting is one of Xometrys many production-capable manufacturing processes. Today we’re going to explore a specific method of the process, gravity die casting. It is an old but serviceable and enduring manufacturing technique that holds a prominent place in modern industry and may be the key to making your product cost-effective and profitable. The gravity die casting technique involves making both simple and highly complex metal components by simply pouring molten metal into a reusable, steel cavity mold tool. Gravity die-cast parts can be of great quality and have very low porosity when the process is executed correctly.
Many Xometry customers ought to be considering the appealing simplicity of gravity die casting, so we are here to make it clear how easy and productive this process can be when used right.
Gravity die casting is a manufacturing process you can specify to produce high-quality metal parts with complex shapes and a relatively good surface finish. It's a type of die casting method because it uses a die, but it differs greatly in complexity from the pressurized and squeeze-cast methods. One of its major advantages is the simplicity of the equipment and the potential to use it in traditional and very low-tech foundry conditions.
It is widely viewed as an effective mass-production tool for producing metal components with moderate dimensional accuracy, consistent quality, and relatively short cycle times. This assertion is supported by the extensive use of the process across many moderate and high-volume sectors of manufacturing. The process is well-suited for demand ranging from 250 to 50,000 units per annum. Using cast iron or steel molds provides greater repeatability, lower labor, and improved cost-effectiveness in comparison to other casting methods, such as sand casting.

Gravity casting works by allowing molten metal to flow gently into a permanent mold under the influence of gravity alone. Listed below, you’ll find a detailed breakdown of the steps involved in gravity die casting:
Before starting the gravity die casting process, the die (also known as the mold) is preheated to a certain temperature to suit the charge metal. This prevents cold spots and ensures uniform solidification of the fill. This step helps to reduce thermal shock, improving the longevity of the die. Additionally, a release agent or coating is commonly applied to the inner surfaces of the die cavity. This coating helps facilitate the removal of the solidified part once the casting process is complete, by reducing sticking. Dies erode due to molten metal contact, especially in turbulent flow areas, because some casting metals can be quite abrasive. Die coating reduces this erosion, maintaining surface integrity for more cycles, whereas otherwise, the roughness would increase casting stick and defects.
Once the die is preheated and coated, it is securely clamped together. Molten metal, typically aluminum or other non-ferrous alloys, is then poured into a pouring basin or runner system that leads to the die cavity. The molten metal enters the mold cavity under the force of gravity alone, hence the name "gravity die casting." The carefully controlled pouring process helps minimize turbulence and air entrapment, resulting in better-quality castings. Filling from below allows the smooth upward rise of the charge meniscus and assists in driving out air and maintaining low turbulence.
As the molten metal is introduced into the mold cavity, it cools rapidly. Solidification starts first when the charge contacts the relatively cooler surfaces of the mold and progresses inward toward the center of the casting cross-section. The metal fill cools rapidly in the mold cavity, solidifying first at the cooler mold surfaces and thinner sections, progressing inward. Preheated molds ensure consistent solidification rates, preventing premature solidification in thin sections that could block metal flow. Solidification time varies with metal type and part design. Mold preheating benefits include avoiding thermal shock, maintaining molten metal temperature for proper flow, and reducing thermal stress in solidifying casting. The time required for solidification depends heavily on the type of metal being cast, the mass of the tool and charge, and the design of the part.
After the charge has fully solidified within the die cavity, the clamps holding the die closed can be released. The opened die reveals the solidified casting that will precisely mirror the cavity it fills, with good dimensional accuracy and great repeatability between casts. The application of the release agent during the initial steps should allow the easy removal of the casting from the die.
Once the casting is removed from the die, it may undergo further processing, such as machining, to achieve the desired final shape and surface finish, remove vent, fill and flash attachments, and improve local precision in areas of higher tolerance than the casting method can achieve. The decision to machine the part depends on its intended use and the required level of precision, as well as the quality of the die machining/fit.
The production speed of the gravity die casting process varies widely as a consequence of various factors, including the material being cast, the complexity of the part's design, and the size of the casting. The entire gravity die casting process typically takes anywhere from a few minutes for simpler castings to several hours for larger or more intricate parts that have longer cooling times. Cycle times can be reduced somewhat, although not without the potential for quality risks. Careful design of the casting process parameters, die design, and material selection allow for the balance of production and casting quality.
A number of materials are compatible with gravity die casting. Some of the most common are listed below:
Certain low-alloy steels with relatively lower melting points can be used for gravity die casting applications where specific mechanical properties are required. That being said, steel is rarely used to create die-cast parts. Instead, steel is most often used in the mold making step of the process. Steel's elevated melting point and retention of physical properties when hot make it well-suited for casting molds.
Magnesium and magnesium-aluminum alloys are commonly used with gravity die casting due to their low density, very high strength-to-weight ratio, and excellent machinability. This results in strong components with low mass for weight-critical applications across multiple industries: automotive, sporting goods, aerospace, and more. Magnesium castings offer considerable advantages in market sectors where lightweight components are crucial, providing performance benefits in fuel consumption and acceleration. However, the intense and vigorous flammability hazard that heated magnesium presents is a huge process risk and must be carefully managed using either a flux or a nitrogen atmosphere to exclude oxygen.
At Xometry and across the industry as a whole, aluminum and its broad range of alloys are the most commonly exploited materials for gravity die casting due to their relatively low melting point, good fluidity when molten, relatively low cost, and favorable mechanical properties in the finished product. These make it an ideal choice for a wide range of applications. Aluminum gravity castings are extensively employed in automotive parts, aerospace structural and actuator components, consumer electronics, and industrial components. To learn more about this material, see our guide on Aluminum Alloy.
Cast iron is appreciated for its low raw material cost, toughness, and excellent wear resistance. It also offers good heat resistance and vibration-damping properties. It can be cast using gravity die casting, but because of its high liquefaction temperature and generally more complex casting process, it is now uncommon to die-cast it compared to other materials.
Copper alloys are widely used in gravity die casting, particularly for parts requiring good electrical conductivity or excellent thermal conductivity, such as bus bars, switch gear, and interconnect components in electrical systems. Copper's high melting point and greater thermal conductivity present some challenges during the casting process, requiring careful control of the casting parameters to enable high-quality copper alloy castings to be produced consistently.
Zinc and zinc alloys, such as ZAMAK, are widely used in gravity die casting due to their relatively low melting points, very low viscosity in the melt, and the naturally good surface finish they produce. Zinc castings find applications in a number of industries, including electronics, decorative hardware, and automotive/industrial components. The ability to reproduce the fine details of a mold makes zinc, especially ZAMAK alloys, a popular choice for decorative items. At Xometry, we primarily offer ZAMAK 2 (ZA-2) and ZAMAK 3 (ZA-3) alloys for our zinc die-cast materials.
One major drawback of gravity die casting is that it can be quite costly, given the cost to machine accurate dies and the relatively high labor cost in the process. Providing an exact estimate of what the process will cost is impossible because the price per part will differ on a project-by-project basis by weight of shot, volume of product required, and degree of post-processing. The complexity of the part being cast plays a crucial role. Intricate designs, thin walls, and undercuts will tend to result in higher costs as they’ll need more specialized tooling and slower and more cautious production processing.
The tooling costs for gravity die casting varies hugely, between possibly a few hundred dollars for a part requiring a simple mold to $100,000 and more for complex castings such as engine blocks and gearbox housings, which require much more elaborate tooling setups.
A primary alternative to die casting is sand casting; however, the cost benefit really depends on volume. Sand casting has considerably lower establishment/tooling costs but much higher per-unit production costs compared to gravity die casting, given the extensive use of skilled labor in the sand process. Sand-cast products are typically not as dimensionally accurate as their gravity die-cast equivalents. To learn more, see our guide: What is Sand Casting.
