Types of Aluminum Casting

1. High Pressure Die Casting

High-pressure aluminum die casting is a precision manufacturing process where molten aluminum is injected under high pressure into a steel mold, known as a die, to form products. This method is ideal for producing thin-walled aluminum components in high volumes. High-pressure die casting is known for producing parts with minimal machining and finishing required, making it an efficient choice for precision parts.

2. Low Pressure Die Casting

In low pressure die casting, molten aluminum is transferred from an airtight furnace into a metallic tool through a rising tube under low pressure. This method is often used when a small production volume is required or when heat treatment is needed to enhance the material's mechanical properties. It is typically used for producing thicker aluminum products, offering the same surface finish and tolerances as gravity die casting, but at a higher tooling cost.

3. Gravity Die Casting

Gravity die casting involves the pouring of molten aluminum into molds or cores made from steel or other metals. This method often involves the application of a vacuum, and it produces castings stronger than those made by die casting or sand casting. Gravity die casting is especially useful for parts requiring permanent cores that are difficult to remove. This process is also called aluminum gravity casting, commonly used in China.

4. Sand Casting

Sand casting is the most versatile method for producing aluminum products, often chosen for intricate designs or large castings. It begins with a pattern of the finished part, which is pressed into a fine sand mixture to form the mold. The pattern is slightly larger than the final part to accommodate aluminum shrinkage during solidification and cooling. While sand casting is slower than die or permanent mold casting, it is generally more economical for small quantities or complex, large designs.
