FAQs for Die Casting
What is Die Casting?
Die casting is a manufacturing process in which molten metal is injected into a mold cavity under high pressure. The mold, or die, is made of two parts, and it has a cavity that is the same shape as the final product. When the molten metal is injected, it fills the cavity and takes on the shape of the mold. The metal is then cooled and solidified, and the finished product is ejected from the mold.
What is the process of die casting?
The die casting process includes clamping the mold, pouring, injecting, opening the mold, core pulling, ejecting, removal, spray coating, reset mechanism, and repeating the process.
- Clamping: The mold is closed, and it is ready for casting.
- Material pouring: A machine operator or robotic arm pours the molten metal into the material cylinder.
- Injection: The molten metal is injected into the mold cavity according to the process parameters.
- Mold opening: The mold is opened, and the core is pulled out using the angled guide pillar and synchronized core pulling.
- Core pulling: The mold is pushed out sideways using the core pulling device so that it can be pushed out easily. If it is front (fixed) mold core pulling, the core needs to be pulled out before opening the mold.
- Ejecting: The casting is pushed out of the mold using the ejection mechanism for easy removal.
- Removal: The casting is manually or automatically removed from the mold. If there are ejector pins, they must be removed carefully to avoid damage.
- Spray coating: The mold cavity is cleaned, and a release agent is applied before each cycle.
- Reset mechanism: If there are ejector pins below the core, a reset mechanism such as a pull rod is used to protect the mold.
- Close mold and repeat the above process.
What are the advantages and disadvantages of die casting?
Advantages：
- Precision of Dimensions: Die casting processes enable the production of parts that are uniform, dimensionally stable, and accurately meet required tolerances with higher precision compared to many other mass production methods.
- Exceptional Properties: Die-cast products boast high durability and heat resistance.
- High-Speed Production: Large quantities of identical castings can be manufactured without the need for additional post-finishing machining, resulting in efficient mass production.
- Cost-Effective: Die casting tooling equipment has a long lifespan, allowing for the production of components at competitive prices in the market.

The resulting components are single parts without separate welding, fastening, or assembly, providing higher strength and stability.
- Multiple Finishing Techniques: Die casting enables products to be manufactured with various finishing techniques such as smooth or textured surfaces. This allows for plating or coating without complex preparations.
- Versatile Geometries: Die casting technologies offer the ability to produce components with various geometries such as fastening elements, bosses, tubes, holes, external threads, and more.
Disadvantages：
- Limited Compatibility with High Melting Point Metals and Alloys: Die casting may not be a suitable manufacturing process for metals and alloys with high melting points, such as steel.
- Limited Size Range: Die casting is not suitable for casting large parts.
- High Tooling Costs: The tooling required for die casting can be expensive, making it less accessible for smaller-scale production runs.
- Lengthy Delivery Time: Due to the complexity and tooling required for die casting, it can lead to longer lead times for production and delivery.
- Porosity Concerns: There is a potential for porosity in die cast products, which can trap gases during the casting process.
What are the types of die casting?
High-Pressure Die Casting: This method involves injecting the molten metal into the mold at high pressures and speeds. It is ideal for producing complex parts with tight tolerances.
Low-Pressure Die Casting: This method is similar to high-pressure die casting, but the molten metal is injected into the mold at a lower pressure. It is typically used for larger, more complex parts.
Gravity Die Casting: This is a casting process where gravity is used to fill the mold with molten metal instead of pressurized injection. It’s primarily used for casting large, heavy parts that can’t be produced through other means like low-pressure or high-pressure die casting.
Why does die casting require high pressure?
Die casting requires high pressure because it involves the injection of molten metal into a mold or die cavity under high pressure. The high pressure is needed to fill the mold completely with the molten metal and to ensure that it solidifies quickly and evenly in order to produce consistent and high-quality parts.
To fill the mold cavity: The high pressure allows the molten metal to flow quickly and uniformly into all parts of the mold cavity, ensuring that there are no voids, porosity, or other defects in the finished product.
To overcome solidification resistance: The high pressure applied also helps to overcome the natural resistance of the liquid metal to solidify, which allows the metal to flow into the smallest crevices of the mold cavity.
To prevent any air pockets or bubbles: The high pressure helps to prevent the formation of any air pockets or bubbles within the molten metal, which can cause defects in the finished product.
To speed up the process: The high pressure allows for the efficient production of high volumes of parts in a short amount of time, making die casting an economical and efficient way to produce complex and intricate shapes.
What is the maximum wall thickness for pressure casting?
The maximum wall thickness for die casting depends on several factors such as the material being used, the size and geometry of the part, and the die casting process being employed.
Aluminum: For aluminum alloys, the maximum wall thickness should not exceed 0.5 inches or 13 mm. Larger wall thicknesses can cause issues like porosity, shrinkage, and warping.
Zinc: For zinc alloys, the maximum wall thickness is around 0.25 inches or 6 mm. Wall thicknesses over this range can result in defects such as sink marks, porosity or voids.
Magnesium: For magnesium alloys, the maximum wall thickness should ideally not exceed 0.125 inches or 3 mm. Any thickness above this range can cause issues like distortion, cracking, and porosity.
Is die casting cost effective?
Yes, die casting is a cost-effective method for producing high-quality metal parts in large quantities.
High production rates: Die casting is a highly efficient process that can produce large quantities of parts quickly and consistently, minimizing manufacturing cycle times and often reducing labor costs.
Low material waste: Die casting generates very little material waste as the metal is melted and then injected into precision-crafted dies. The recycled metal can be used in subsequent casting cycles, further reducing material expenses.
High accuracy and precision: Die casting allows for precise and accurate components with tight tolerances, reducing the need for post-processing and secondary operations, which can add to costs.
Design flexibility: Die casting allows for the production of complex parts in a single operation, eliminating the need for multiple components and assembly operations, which can result in additional manufacturing savings.
Long tool life: Typically, die casting dies can last for hundreds of thousands of cycles or even millions of cycles, which makes it ideal for long-term manufacturing runs.
Repeatability: With the use of modern machinery and technology, die casting is highly automated, and hence, the repeatability of parts is high with minimal human interference.
