Why is it called die casting?

Die casting is named so because it involves the use of a metal mold, known as a die, into which molten metal is injected under high pressure. The term "die" refers to the mold or tool that shapes the metal into the desired form during the casting process.

Is high-pressure die casting for plastics?

No, highpressure die casting is primarily used for metals, not plastics. In this process, molten metal is injected into a die under high pressure to produce complex and detailed metal parts with high accuracy and surface finish. Plastics, on the other hand, are commonly processed using injection molding techniques.

What is the difference between low-pressure and high-pressure die casting?

The main difference lies in the pressure used to inject molten metal into the die. In low-pressure die casting, the metal is typically forced into the mold at a lower pressure, allowing for the production of larger and more massive parts. High-pressure die casting, as the name suggests, involves injecting molten metal at significantly higher pressures, resulting in the production of smaller and more intricate parts with finer details.

What is the difference between high-pressure casting and gravity casting?

The key distinction between high-pressure casting and gravity casting lies in the method of metal injection. High-pressure casting involves injecting molten metal into the die under substantial pressure, enabling the production of detailed and high-precision parts. In gravity casting, on the other hand, the molten metal is poured into the mold using the force of gravity, making it a more suitable method for simpler shapes and larger parts that do not require the same level of precision.

What is the alternative to high-pressure casting?

An alternative to high-pressure casting is gravity casting. Gravity casting involves pouring molten metal into a mold without the use of high pressure. While it is less suitable for highly detailed and precision parts, gravity casting is well-suited for larger and simpler shapes. Other alternatives include low-pressure die casting and sand casting, each with its own set of advantages and limitations depending on the specific requirements of the casting project.

How Does High Pressure Die Casting Work？

Prepare the Mold

The first step in High Pressure Die Casting is the preparation of the mold. The mold, also known as the die, is a carefully designed cavity that determines the final shape of the product. It's typically made of two parts, the cover die, and the ejector die, which come together to form the desired shape. The mold is preheated to a specific temperature to ensure proper metal flow and solidification during the casting process.

Inject the Material

Once the mold is ready, the next step is to inject the molten metal into it. This is a crucial stage and can be executed through two main methods: Hot Chamber Injection and Cold Chamber Injection.

Hot Chamber Injection

Hot Chamber Injection is suitable for metals with low melting points, such as zinc, tin, and lead. In this method, the injection system is immersed in a molten metal bath. The plunger, which is part of the injection system, is used to push the molten metal into the die cavity under high pressure. This process ensures a continuous and fast casting cycle, making it efficient for mass production.

Cold Chamber Injection

For metals with higher melting points, like aluminum and copper, Cold Chamber Injection is employed. In this method, the molten metal is poured into a separate chamber, and a plunger is used to transfer the metal into the die cavity. The advantage of this approach is that it prevents the contact between the molten metal and the injection system, reducing wear and prolonging the life of the components.

Part Injection

Once the molten metal has solidified inside the mold and taken the shape of the cavity, the next step is to remove the cast part from the mold. The mold is opened, and the ejector pins push the casting out. This step requires precision and care to avoid any damage to the newly formed part.

Trim the Excess Material

After the part is removed from the mold, it often contains excess material, known as flash, which needs to be trimmed off. Flash occurs at the parting line of the mold, where the two halves meet. Trimming is essential for achieving the final desired shape and ensuring that the part meets the required specifications.
