Types of Die Casting Processes
Fioria offers complete die casting solutions, employing both Hot Chamber and Cold Chamber methods to accommodate various materials and meet specific project needs.
Hot Chamber Die Casting
This method is highly efficient for metals with lower melting points like zinc and magnesium. Featuring a furnace integrated with the casting machine, it enables rapid and continuous production cycles. Molten metal is injected directly from the heated chamber into the mold, making it ideal for parts that demand precise dimensional accuracy and improved mechanical properties.
Cold Chamber Die Casting
This method is ideal for metals with higher melting points, such as aluminum and copper alloys. In this process, molten metal is manually poured into the cold chamber before each injection, which helps shield the equipment from extreme heat, increasing its longevity and efficiency. It is especially well-suited for producing large, robust components with intricate designs and excellent strength.
Applications of Die Casting

Post-Processing Needs: Although typically minimal, some parts may require additional machining or finishing to achieve precise tolerances or desired surface quality.
FAQs
Die casting is a manufacturing process that involves injecting molten metal into a mold cavity under high pressure. The mold, referred to as a “die,” consists of two precisely machined, hardened steel components that function similarly to an injection mold. The process unfolds as follows:
Mold Preparation: The die is coated with a lubricant to ease part removal and help regulate temperature during casting.
Molten Metal Injection: Molten metal is forced into the die at high pressures—typically between 10 and 175 megapascals (1,500 to 25,000 psi)—and maintained until solidification.
Cooling and Solidification: The metal rapidly cools and hardens within the mold, forming the final shape.
Ejection: After the part has solidified, the die halves open, and the finished casting is ejected.
Trimming: Excess material, such as gates, runners, and flash, is removed to refine the part.
This process ensures precise, high-quality metal components suitable for mass production.
When designing components for die casting, several critical factors should be taken into account to optimize both functionality and manufacturability:
Wall Thickness: Aim for uniform wall thickness throughout the part to ensure consistent cooling and solidification. This helps reduce the likelihood of defects such as warping or internal stresses. While thinner walls are advantageous for faster cooling and material efficiency, their viability depends on the chosen metal and part complexity.
Draft Angles: Integrate appropriate draft angles into the design to facilitate the smooth ejection of the part from the die. A typical draft angle ranges from 1 to 2 degrees, adjusted according to the part’s depth and geometry.
Fillets and Radii: Avoid sharp edges by incorporating fillets and rounded corners. This minimizes stress concentrations and improves the molten metal flow, reducing the risk of cracks and enhancing part integrity.
Gating System: Create an effective gating layout to guide the molten metal into the die efficiently. Well-positioned gates help minimize turbulence and reduce air entrapment, directly impacting the casting’s quality.
Venting: Ensure adequate venting is included in the mold design to allow trapped air and gases to escape during the injection phase. This prevents porosity and ensures complete cavity filling.
Simplified Geometry: Streamline the part design by avoiding unnecessary undercuts and overly complex features. Simplification reduces tooling costs, shortens lead times, and improves overall process efficiency.
By addressing these elements early in the design phase, you can enhance both the quality and cost-effectiveness of die cast parts.
In die casting, vibrations refer to mechanical oscillations occurring within the machines and molds during the process.
Vacuum Pressure Casting: This technique creates a vacuum inside the mold cavity to reduce air entrapment and porosity. Vibrations can disrupt the vacuum environment, causing defects in the finished part.
Low Pressure Casting: Molten metal is introduced into the mold under low pressure. Vibrations in this process can disturb the steady flow of metal, negatively affecting the uniformity and quality of the casting.
Semi-Solid Die Casting: Semi-solid metal is injected into the mold in this method. Vibrations can impact the thixotropic behavior of the metal, altering the fill pattern and the final part’s characteristics.
Squeeze Die Casting: After the mold is initially filled, additional pressure is applied to improve density and mechanical strength. Vibrations during this stage may cause uneven pressure distribution, leading to inconsistencies in the casting.
The lead time for producing die cast tooling typically ranges from 2 to 12 weeks. This period begins with the initial design phase, where the part concept is developed and specifications are defined, and continues until the mold is fully completed. Factors such as the part’s design complexity, the selected casting metal, and the required precision for the final product greatly affect the tooling timeline. After machining, the mold undergoes thorough testing to verify quality standards. Any necessary adjustments or modifications to address defects or enhance performance can extend the overall lead time. Clear and ongoing communication between the manufacturing team and the client is crucial to streamline the process and ensure production deadlines are met.
Die casting is a precision manufacturing method capable of achieving very tight tolerances, making it well-suited for complex, high-volume parts. Typically, tolerances depend on the part’s size, the metal used, and the specific casting technique. For standard sizes, tolerances generally range from ±0.1 mm for smaller dimensions under 25 mm, up to ±0.5 mm for dimensions as large as 250 mm. Even tighter tolerances, down to ±0.02 mm, can be attained through additional post-machining processes.
Material selection also significantly impacts tolerance, as metals like aluminum and zinc alloys exhibit different shrinkage rates and mechanical properties that affect final dimensional accuracy. Advanced die casting methods such as vacuum casting or squeeze casting can further improve tolerance control by reducing porosity and enhancing the metal’s structural integrity.
Yes, post-machining of die cast parts is not only feasible but often essential to achieve the required precision and surface quality that die casting alone may not deliver. Post-machining enables tighter tolerances and smoother finishes, which are vital for both high-performance and aesthetic demands. Common post-machining techniques include drilling, milling, and CNC machining, which refine the die cast part’s features to meet exact specifications.
Moreover, post-machining can address minor defects from the casting process, such as porosity or surface flaws. It also allows for the addition of intricate features and fine details that casting alone cannot produce. By combining die casting with post-machining, manufacturers benefit from the speed and cost-effectiveness of die casting for creating the basic shape, while achieving the precision and finish quality of CNC machining for critical dimensions.
