Alloy casting process
Alloy casting transforms raw metal into usable parts. Workers use heat, molds, and delicate steps to shape the metal. Metal casting is crucial for manufacturing products such as automobiles, electronics, and medical devices. The process involves multiple steps that ultimately transform solid metal into finished parts.
Melting and Shaping
The first step is melting. Workers heat the metal alloy to a liquid state. Each alloy has a different melting point. For example, pure aluminum has a melting point of 660.3°C. Zinc-aluminum alloys have melting points between 426°C and 482°C. Magnesium-aluminum alloys have melting points between 621°C and 704°C. The appropriate temperature is key to achieving good casting results.
After melting, workers remove gases and improve the melt, which helps the casting maintain strength and high quality. Next, they pour the hot metal into a mold. The mold shapes the metal as it cools. The metal solidifies rapidly within the mold. As it cools, crystals form, and the metal gradually hardens. Finally, the worker removes the solidified casting from the mold.
The main steps of the alloy casting process are as follows:
- Melting: Heating the metal alloy until it melts.
- Degassing and Modification: Removing gases and improving the melt.
- Pouring: Pouring the molten metal into a mold.
- Solidification: Allowing the metal to cool rapidly within the mold.
- Solidification: As the metal hardens, crystals form.
- Casting: Removing the solidified casting from the mold.
Sometimes, problems arise during melting and shaping. These problems, known as defects, reduce the strength of the casting. The table below lists common defects, their causes, and solutions.
| Defect Type | Description | Causes | Prevention Methods |
|---|---|---|---|
| Porosity | Small holes or air pockets in the metal, weakening it. | Trapped gases, poor venting, contamination. | Ensure good venting, control pouring speed, and keep the environment clean. |
| Shrinkage | Decrease in metal volume as it cools, causing empty spaces. | Thick areas or uneven cooling. | Use risers, control cooling rate, and add insulation. |
| Cold Shuts | Weak seams where molten metal streams do not fuse. | Slow pouring or low temperature. | Ensure high pouring temperature and smooth metal flow. |
| Misruns | Incomplete castings where the mold is not fully filled. | Low pouring temperature or speed. | Increase pouring temperature and preheat the mold. |
| Inclusions | Impurities or particles trapped inside the casting. | Contamination or improper filtering. | Clean the mold, filter molten metal, and avoid contamination. |
| Hot Tears | Cracks formed due to uneven cooling. | Stress from uneven cooling. | Use flexible mold materials and control cooling rate. |
MORELUX employs specialized casting processes to reduce defect rates. The company rigorously inspects parts at every stage of production, utilizing X-rays and other detection methods to identify problems early. Their team meticulously controls temperatures and uses pure alloy materials to ensure the superior quality of every casting.
High-Pressure Die Casting
High-pressure die casting is a specialized metal casting process. This process injects high-temperature metal into a steel mold at extremely high speed and pressure. The metal fills every space in the mold, perfectly filling even the smallest corners and sharp edges. This method can create shapes that are impossible to achieve with other casting processes.
High-pressure die casting offers numerous advantages:
- It can produce dimensionally precise, smooth-surfaced parts.
- This process enables the rapid production of robust and highly detailed parts.
- Die casting molds can withstand high pressure, which is especially important for metals such as aluminum, zinc, and magnesium.
- Rapid filling results in a more refined and robust metal structure.
- This process reduces porosity and increases the strength of castings.
The table below shows the dimensional accuracy of different casting processes:
| Casting Process | Tolerances Achievable |
|---|---|
| High-Pressure Die Casting | ±0.05–0.3% (±0.05–0.3 mm per 100 mm) |
| Investment Casting | ±0.1–0.5% (±0.1–0.5 mm per 100 mm) |
| Sand Casting | ±0.5–2.0% (±0.5–2.0 mm per 100 mm) |
MORELUX uses high-pressure die casting technology to manufacture precision parts for a wide range of applications. Its process utilizes advanced equipment and rigorous quality control to ensure the accuracy and strength of each part.

Types of Alloy Casting
Alloy casting uses different methods to form metal parts. These methods are widely used in various industries. Each method has its own steps and advantages. The main types include sand casting, die casting, and investment casting. These methods are used to manufacture parts made of aluminum, zinc, and magnesium alloys. The choice of casting method depends on the size, shape, and application of the part.
Sand casting
Sand casting is a long-established and widely used alloy casting method. Workers use templates to create molds in sand, then pour hot alloy into the sand mold. After the alloy cools, the sand is removed. This is the finished part. Sand casting is ideal for large or complex-shaped parts. It is commonly used to manufacture engine blocks, gearbox housings, pump bodies, and mechanical parts. Sand casting is also used to manufacture parts for bridges, gears, flywheels, fuel tanks, and electronic components.
