Advantage of die casting

1. The production efficiency is high, and the production process is easy to realize mechanization and automation. Generally, the cold chamber die-casting machine casts 50~90 times per hour on average, while the hot chamber die-casting machine casts 400~900 times per hour on average, with high production efficiency.

2. Die castings have high dimensional accuracy and surface quality. The general tolerance grade of die castings is it13~it15 in gb/t 1800-2009, and the higher accuracy can reach it10~w 11. The surface roughness is 3.2~1.6um, and locally 0.8um. Because of the high dimensional accuracy and high surface quality of die castings, die castings with low requirements can be used directly, avoiding machining or using less machining, improving the utilization of alloy and saving a lot of machining costs.

3. Die castings have high mechanical properties. The metal melt cools fast in the die casting mold and crystallizes under pressure. Therefore, the layer near the surface of the die casting has fine grains, dense structure, high strength and hardness.

4. It can die cast complex thin-walled parts. Die castings can have complex part shapes, and the wall thickness of parts can be small. The minimum wall thickness of aluminum alloy die castings is 0.5mm, the minimum wall thickness of zinc alloy die castings can reach 0.3mm.

5. Parts of other materials can be embedded in die castings. In this way, valuable materials and processing costs can be saved, parts with complex shapes can be obtained, the performance of parts can be improved, and the assembly workload can be reduced.

6. Compared with sheet metal parts, the shape of die-casting parts can be more complex, and the wall thickness of parts can be changed. One die-casting can replace several sheet metal parts, so as to simplify the product structure.

7. Compared with plastic parts, die castings have advantages in strength, conductivity, thermal conductivity and anti electromagnetic radiation.

8. Compared with machined parts, die castings are light in weight and low in processing cost.

9. Compared with other casting methods, die-casting products have high dimensional accuracy, good surface quality and high production efficiency.

Are there any corrosion-resistant grades of cast aluminium?

Yes, there are corrosion-resistant grades of cast aluminium that are specifically formulated to have enhanced resistance against corrosion. Here’s a detailed explanation:

Cast aluminium alloys are typically composed of aluminium as the primary element and various alloying elements added to enhance specific properties. The choice of alloying elements and their composition can significantly influence the corrosion resistance of cast aluminium. Some commonly used corrosion-resistant grades of cast aluminium include:

  • Aluminium-Silicon Alloys:
  • Aluminium-silicon alloys, such as the popular A356 and A413 grades, are widely used in casting applications due to their excellent corrosion resistance. These alloys contain silicon as the primary alloying element, which forms a protective oxide layer on the surface of the aluminium, enhancing its resistance to corrosion caused by exposure to moisture, salts, and other corrosive elements.

  • Aluminium-Magnesium Alloys:
  • Aluminium-magnesium alloys, such as the 5000 series (e.g., 5052 and 5083), are known for their good corrosion resistance. The addition of magnesium provides a self-healing property to the aluminium, as the magnesium reacts with oxygen to form a protective magnesium oxide layer. This oxide layer helps prevent further corrosion and degradation of the aluminium surface.

  • Aluminium-Zinc Alloys:
  • Aluminium-zinc alloys, such as the 7000 series (e.g., 7075), exhibit high strength and good corrosion resistance. The addition of zinc enhances the corrosion resistance by forming a protective zinc oxide layer on the surface of the aluminium. These alloys are commonly used in applications where both strength and corrosion resistance are critical, such as in aerospace and military industries.

  • Aluminium-Copper Alloys:
  • Aluminium-copper alloys, such as the 2000 series (e.g., 2024), are known for their high strength and moderate corrosion resistance. The addition of copper improves the overall strength and mechanical properties of the aluminium, while also providing some degree of corrosion resistance. However, these alloys may require protective coatings or surface treatments for enhanced corrosion protection in more aggressive environments.

It’s important to note that while these corrosion-resistant grades of cast aluminium offer improved resistance to corrosion, they may still require proper maintenance and care to ensure their long-term performance. Factors such as exposure to harsh environments, temperature variations, and the presence of corrosive agents can still affect the corrosion resistance of cast aluminium, albeit to a lesser extent compared to non-resistant grades.

When selecting a specific grade of cast aluminium for a particular application, it is essential to consider the environmental conditions, intended use, and required level of corrosion resistance. Consulting with material suppliers or experts in the field can provide valuable guidance in choosing the most suitable corrosion-resistant grade of cast aluminium for a given application.

How does cast aluminium differ from wrought aluminium?

Cast aluminium and wrought aluminium are two different forms of aluminum that differ in their manufacturing processes and properties. Here’s a detailed explanation:

Manufacturing Process:

  • Cast Aluminium:
  • Cast aluminium is produced by pouring molten aluminium into a mold or die, allowing it to solidify and take the shape of the mold. This process is called casting. Cast aluminium components are typically created in large batches using specialized casting techniques such as sand casting, die casting, or investment casting.

  • Wrought Aluminium:
  • Wrought aluminium is produced through a series of mechanical processes, typically starting with the casting of ingots or billets. The ingots or billets are then subjected to various shaping processes, such as rolling, extrusion, forging, or drawing. These processes deform the aluminium material and shape it into the desired form, such as sheets, plates, bars, or profiles.

Mechanical Properties:

  • Cast Aluminium:
  • Cast aluminium has a coarse-grained microstructure due to the rapid solidification process during casting. This microstructure can result in lower mechanical strength and reduced ductility compared to wrought aluminium. However, cast aluminium can still exhibit sufficient strength and rigidity for many applications.

  • Wrought Aluminium:
  • Wrought aluminium has a refined and more uniform microstructure due to the mechanical processing it undergoes. This results in improved mechanical properties, including higher strength, better ductility, and enhanced toughness compared to cast aluminium. Wrought aluminium is often preferred for applications that require superior mechanical performance.

<strong.Surface Finish:

  • Cast Aluminium:
  • Cast aluminium surfaces typically have a textured or slightly rough appearance due to the nature of the casting process. The surface finish of cast aluminium can vary depending on the casting method used and the quality of the mold. Additional machining or surface treatments may be required to achieve a smoother or more polished finish.

  • Wrought Aluminium:
  • Wrought aluminium surfaces can achieve a smoother and more refined finish compared to cast aluminium. The mechanical processing involved in the production of wrought aluminium helps create a more uniform surface texture. Wrought aluminium can be further treated or finished to achieve various surface qualities, such as brushed, polished, or anodized finishes.

Application Suitability:

  • Cast Aluminium:
  • Cast aluminium is commonly used for applications that prioritize ease of manufacturing, complex shapes, or cost-efficiency. It is often found in automotive components, household appliances, decorative items, and low-stress structural applications.

  • Wrought Aluminium:
  • Wrought aluminium is preferred for applications that require superior mechanical properties, tight tolerances, or specific surface finishes. It is commonly used in aerospace components, high-strength structures, precision parts, and applications where formability and strength are critical.

It’s important to note that the choice between cast aluminium and wrought aluminium depends on the specific requirements of the application, considering factors such as mechanical performance, surface finish, complexity of the design, and cost considerations.
