What is Aluminum Die Casting?

The main raw material of aluminum alloy die-casting is aluminum alloy ingots. The melted aluminum alloy liquid enters the mold cavity through high pressure and forms fixed-shaped aluminum alloy parts after cooling under pressure.

Modern industry is in great need of this kind of metal suitable for mass production. The aluminum die casting production process of the parts, it has relatively mature production technology and post-processing technology.

Able to create perfect and complex metal parts, the aluminium die-casting process involves the use of a furnace, metal, a die-casting machine, and a mold.

During the aluminum die casting process, some parameters need to be set for the die-casting machine, including: “injection force,” “pressure ratio,” “injection speed,” “mold temperature,” “filling time,” and “holding pressure time.” The setting of these parameters affects the final molding quality of the product.

  • Injection force refers to the pressure generated during the die casting process, produced by the pressure pump. The pressure pump transports the molten aluminum alloy solution to the injection piston, which then applies pressure to the metal in the pressure chamber. The pressure applied to the liquid metal is a critical factor in achieving structurally dense and well-defined castings. Therefore, it’s important to understand and control the pressure variations acting on the liquid metal throughout the die casting process.
  • Injection speed refers to the speed of the injection head during the die casting process, which can be categorized as slow or fast injection. Generally, slow injection speeds range from 0.1 to 0.5 meters per second, while fast injection speeds range from 0.1 to 1.1 meters per second. Factors that determine the injection speed include the thickness of the casting wall (thinner walls require faster injection), the complexity of the casting shape (more complex shapes require faster injection), the prominence of the casting’s surface (larger prominences require faster injection), and the length of the gating path (longer gating paths require faster injection).
  • Pouring temperature refers to the average temperature of the mold during the casting process. Typically, the lowest possible temperature that ensures proper molding and the desired surface quality is used. The casting temperature for aluminum alloys ranges from 650°C to 720°C, with the casting temperature being reduced for alloys with good flowability. For thin-walled and complex castings, a higher casting temperature may be used, while for large molds with good heat dissipation, the casting temperature may be slightly higher.
  • Mold temperature refers to the temperature of the mold during the production process. The typical mold temperature for aluminum alloy die casting molds is in the range of 200°C to 280°C. In general, thinner castings and more complex structures require higher mold temperatures.
  • Filling time is the time required for the molten aluminum metal to start filling the mold cavity during the die casting process. It typically ranges from 0.01 to 0.1 seconds. The choice of filling time depends on various factors, including the casting’s pouring temperature, mold temperature, the distance of thick-walled sections from the gate, the alloy’s heat of fusion, and the effectiveness of the venting system.
  • Holding pressure time, also known as holding time, is the time required for the solidification of the metal in the mold under pressure after it has been filled. Holding pressure helps to crystallize the solid metal under pressure, ensuring that the castings have a dense internal structure. Holding pressure times vary depending on factors such as the alloy’s solidification temperature range, casting thickness (thicker walls require longer holding times), and the size of the casting.
  • Cooling time is the duration that the casting remains in the mold. It refers to the time from the start of holding pressure until the casting is ejected from the mold. Adequate cooling time ensures that the casting has fully solidified, cooled, and developed sufficient strength. The goal is to minimize cooling time while preventing deformation and cracking of the casting.

These process parameters are crucial for achieving high-quality aluminum alloy die castings. Companies like Yontone, with their extensive experience, are familiar with these terms and concepts used in die casting and employ them to produce excellent results.
