Die Casting Guide - Frequently Asked Questions
1.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.
Die casting is used to create complex metal parts with high accuracy, a good surface finish, and dimensional consistency. This process is particularly suitable for producing large volumes of small to medium-sized metal parts, such as automotive parts, electronic components, and household appliances. The dies used in die casting are typically made of high-strength alloys, which are able to withstand the high pressure and temperature of the process. Overall, die casting is a cost-effective and efficient way to produce high-quality metal parts.
2. 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.
3. 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.

- Porosity Concerns: There is a potential for porosity in die cast products, which can trap gases during the casting process.
4. 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.
5. 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.
6. Hot chamber die casting process
Hot chamber die casting is a process of metal casting, where the molten metal is injected into the cavity of the die under pressure. This process is typically used for casting low melting point alloys such as zinc, magnesium, and some copper alloys.
In the hot chamber die casting process, the melting furnace is attached to the die casting machine, and the molten metal is injected directly into the die. The furnace is kept full of molten metal, and whenever the metal in the die is depleted, more molten metal is automatically transferred from the furnace to the die.
The steps involved in the hot chamber die casting process are as follows:
The die casting machine closes the die.
The piston in the machine moves forward, and liquid metal is forced into the die cavity under high pressure.
The metal is then allowed to cool and solidify, and the die is opened, and the casting is removed.
The scrap from the casting is separated from the finished product.
The die is coated with a release agent before the process is repeated.
Unlike cold chamber die casting, the hot chamber die casting process does not require a separate melting furnace, which makes the process more efficient and suitable for smaller and simpler parts that require high production volumes.
Hot chamber die casting is widely used in the automotive, electronics, and appliance industries due to its versatility, efficiency, and precision in producing parts with complex geometries of consistent quality.
Advantages
Disadvantages
7. Cold chamber die casting process
Cold chamber die casting is a metal casting process that involves injecting molten metal into a mold or die cavity under high pressure. It is commonly used for alloys that have a high melting point, such as aluminum, copper, brass, and other non-ferrous alloys.
In the cold chamber die casting process, the molten metal is first melted in a separate furnace, and then ladled into the cold chamber of the die casting machine. The cold chamber is called so because it is not heated by the molten metal, which helps to reduce the risk of damage to the machine from high-temperature metal. The key steps involved in cold chamber die casting process are:
The die casting machine opens the die.
The molten metal is ladled into the cold chamber of the die casting machine.
The machine then closes the die, and the metal is forced into the die cavity under high pressure.
The metal is allowed to cool and solidify, and then the die is opened, and the casting is removed.
The scrap material from the casting is separated from the finished product.
The cold chamber die casting process is preferred for alloys with a high melting point, which would cause the hot chamber die casting machine to wear out quickly. The process is also suitable for making large parts with complex geometries, and it enables the production of high-quality products. The cold chamber die casting process is widely used in the automotive, aerospace, and electronics industries.

Disadvantages
8. What are the tips for die casting design?
By following these design tips, you can help ensure that your die casting project results in high-quality, cost-effective parts that meet the required specifications and quality standards.
Keep the wall thickness uniform: It is critical to maintain uniform wall thickness across the part to avoid any defects such as porosity, flow marks, and shrinkage. An inconsistent wall thickness can also result in a part that is weak and prone to breaking.
Minimize undercuts: Undercuts (indentations or protrusions in the part design) can make it difficult to eject the final part from the die. Minimizing undercuts by adding draft angles or designing an additional slide into the die can help prevent this issue.
Avoid sharp corners: Sharp corners can cause undesirable defects such as cracking, porosity, and other structural weaknesses. It is advisable to round off corners to reduce stress concentration and improve the part’s overall strength.
Consider the material’s shrinkage rate: Die casting materials shrink as they cool, causing the part to contract. It is essential to consider the material’s shrinkage rate during the design phase to avoid any issues with the part’s dimensions or tolerances.
Design for manufacturability: When designing a part for die casting, it is essential to keep in mind the manufacturing process. A design that is complex, difficult to manufacture or requires many post-processing operations can result in a higher manufacturing cost or defects.
Add ribs or gussets for strength: Die cast parts can benefit from added ribs or gussets to improve their strength and stiffness. These features can make the part more resistant to bending, warping, or breaking.
Use fillets: Fillets are rounded edges that can help reduce stress concentrations and improve the strength and durability of the part.
9. How long does die casting take?
The time it takes to complete a die casting project can vary based on several factors, including the size, complexity, and quantity of the parts being produced, as well as the type of material used and the finishing operations required.

Electrical Components: The production of zinc die-cast electrical components, such as connectors or housing, can take 2-6 weeks to design and create the die, with a production cycle time of 20-40 seconds per part.
Consumer Products: The production of magnesium die-cast components for consumer products, such as camera housings or laptop cases, can take 4-8 weeks to design and create the die, with a production cycle time of 20-60 seconds per part.
10. 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.
In general, to avoid issues like porosity, warping, or shrinkage, designers should aim to maintain a uniform wall thickness throughout the part. It is also important to note that the maximum wall thickness may vary based on the complexity and overall size of the casting, as well as the die casting method being used.
11. 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.
Die casting can be more expensive compared to other casting methods like sand casting or investment casting, but its cost-effectiveness lies in the given advantages. Moreover, as the volume of production required increases, the cost per part decreases, making die casting more cost-effective for large quantities of high-quality parts.
12.What are the best metals to use in die casting?
