Product Description

Product Description

 

Gravity casting is a manufacturing process that involves pouring molten metal into a permanent mold without the use of high pressure. Instead, the earth's gravity is utilized to fill the mold's cavity with the metal. This technique is typically employed for creating intricate parts from various non-ferrous metals, such as aluminum, magnesium, or copper-based alloys.
The product resulting from gravity casting often features excellent dimensional accuracy, a smooth surface finish, and the ability to form complex shapes. It is a cost-effective method suitable for medium to high volume production runs, as the molds used in this process are durable and can be reused multiple times. Gravity casting is widely applied in industries like automotive, aerospace, and industrial equipment manufacturing, where high-quality metal components are essential.

FAQ

1. Q: What types of metals can be used in gravity casting?
A: Gravity casting is suitable for a wide range of metals, especially non-ferrous alloys such as aluminum, magnesium, and various types of brass and bronze. However, ferrous metals like cast iron and steel can also be cast using this method with the appropriate mold materials.

2. Q: How does gravity casting compare to high pressure die casting?
A: Gravity casting typically has lower tooling costs and can produce thicker-walled parts with less porosity. High pressure die casting, on the other hand, can yield higher production rates and tighter dimensional tolerances but often at a higher cost.

3. Q: What are the typical tolerances achievable with gravity casting?
A: While tolerances can vary depending on the material and part design, gravity casting can generally achieve tolerances within ±0.005 inches per inch.

4. Q: Can gravity casting be used for both prototyping and production runs?
A: Yes, gravity casting is versatile enough for both prototyping, due to its relatively low tooling costs, and for medium to high-volume production runs, thanks to the durability of the molds.

5. Q: What is the maximum size or weight for parts produced by gravity casting?
A: The size and weight limitations for gravity cast parts are primarily determined by the capacity of the casting equipment and the ability to handle the mold. Parts can range from a few ounces to several hundred pounds.

6. Q: How does gravity casting handle complex internal geometries?
A: Gravity casting can manage complex internal geometries by using sand cores or other inserts that create the desired internal features as the metal solidifies around them.

7. Q: What kind of surface finish can be expected with gravity cast parts?
A: Gravity casting typically results in a good surface finish, often better than sand casting, due to the smoother mold surfaces. The final finish can vary but is usually suitable for many applications without further treatment.

8. Q: Are there any specific design rules to follow when creating a part for gravity casting?
A: Yes, to ensure a successful gravity casting process, designs should include uniform wall thicknesses where possible, avoid sharp corners and undercuts, and consider draft angles for easy mold release.

9. Q: Can gravity casting molds be used multiple times, and if so, how many cycles can they withstand?
A: Gravity casting molds, made from durable materials like steel, can be used for multiple cycles, often ranging from a few thousand to over a hundred thousand, depending on the complexity of the part and the mold maintenance.

10. Q: How does gravity casting accommodate for metal shrinkage during cooling?
A: Mold design in gravity casting takes into account the shrinkage of metal as it cools. The molds are made slightly oversized relative to the desired final dimensions of the part to compensate for shrinkage. Additionally, risers can be used to supply additional molten metal as the casting solidifies and shrinks.
