An Overview of Permanent Mold Casting

Permanent Mold Casting, also known as gravity die casting, is a metal casting process widely used in the manufacturing industry. It involves pouring molten metal into a permanent mold, typically made from steel or iron, which is designed to be reusable. This process’s reusability gives it a key advantage over other casting processes, such as sand casting, where the mold is destroyed after each use.

Aluminum Permanent Mold Casting

Despite the name, permanent molds do have a limited lifespan. They eventually wear out and need to be replaced. However, they still offer a significant cost advantage for large volume production since the cost per piece decreases with increasing volume.

Why Permanent Mold Casting for Aluminum Castings?

Permanent mold casting is particularly well-suited for aluminum due to the metal’s unique properties. Aluminum’s relatively low melting point (660 ℃) is kind to the mold, extending its lifespan and reducing production costs. Moreover, aluminum’s excellent flow characteristics make it suitable for casting complex shapes and thin walls.

In addition, aluminum castings produced through permanent mold casting have improved mechanical properties compared to those made with sand casting. The cooling rate in a permanent mold is faster, leading to a finer grain structure, which in turn provides superior strength and hardness, as well as improved dimensional stability and accuracy.

Aluminum Permanent Mold Casting Processes

At CFS Foundry, we have mastered the aluminum permanent mold casting process. The first step is designing and producing a mold based on the customer’s requirements. Our experienced engineering team uses advanced CAD software to ensure the design is optimized for the casting process and the final product meets the desired specifications.

After the mold design is finalized, it is machined from high-strength steel or iron. The mold is then preheated to a specific temperature before molten aluminum is poured into it. The high thermal conductivity of aluminum helps it fill the mold cavity completely, achieving even the finest details.

Once the aluminum has solidified, the mold is opened, and the cast piece is removed. Depending on the complexity of the design, cores may be used to form internal cavities. The castings are then heat-treated for stress relief and to enhance mechanical properties.
