Advantages of Magnesium Die Casting

01/

Extremely lightweight
Magnesium’s specific gravity is only 1.74. Whereas aluminum has about 2.55 and iron has about 7.5. Therefore, magnesium is almost 35% lighter than aluminum and 75% lighter than iron. Consequently, it is considered one of the most lightweight structural metals.

02/

Excellent shielding properties
Magnesium parts have exceptional emi/rfi shielding properties. So, magnesium enclosures can protect electrical components from electromagnetic radiation. Thus, this makes it very important for certain applications.

03/

Good castability
Magnesium alloys are known for their castability. The high fluidity of magnesium alloys makes them easy to cast. So, intricate features and thin walls are easier to implement with magnesium alloy casting.

04/

Easy to machine
Magnesium die cast parts are easy to machine. So, they require less time and cost. It could be a good choice when dealing with a die casting project that requires too much secondary machining.

Application of Magnesium Die Casting

Automotive industry

Magnesium die casting is widely used in the automotive industry for parts where weight reduction is crucial without compromising strength.Common components include instrument panels, transmission cases, steering columns, and seat frames.

Aerospace applications

In the aerospace sector, magnesium die-cast parts provide an excellent balance of weight and strength.They’re often used in non-structural areas and, in some cases, for critical components that demand both rigidity and minimal weight.

Electronics and consumer goods

The electronics industry benefits from magnesium’s lightweight and emi/rfi shielding properties, making it ideal for protective housings in devices like laptops, cameras, and smartphones.

Power tools

For power tools used in construction and heavy-duty environments, magnesium die casting offers the perfect combination of durability and lightness.Tools with magnesium components are easier to handle over long periods, reducing operator fatigue while withstanding the rigors of job sites.

Process of Magnesium Die Casting

Step 1: Preparation of magnesium alloy
The first step is to make the magnesium alloy. Magnesium and specified alloying metals are melted in specific quantities. They are heated together until a molten liquid is formed. This controlled melting step takes place within a furnace. The furnace temperatures can go as high as 400-500 degrees celsius.

Step 2: High-pressure injection
The molten magnesium alloy is then pumped into a mold under high pressure. This is the key step in the process, known as high-pressure die casting. The pressure can reach up to 100 mpa in this step.

This guarantees that the mold is filled completely and consistently, with no empty spots. High pressure helps to forge all of the mold’s minute intricacies. The mold is manufactured from a tough and durable material, like steel, which can withstand the conditions of this process.

Step 3: Rapid cooling and solidification
Once the molten magnesium alloy is inside the mold, it quickly cools and solidifies. This is an important phase in the die-casting process. This is because high-speed cooling ensures that all of the mold’s fine details are retained.

Following that, the mold is opened to release the cast. This requires care because finer elements of the design May be ruined. The magnesium cast is further processed after extraction, like trimming and surface finishing.

FAQ

Q: Why is magnesium used in die casting?

A: Its unique features such as castability, ease of machining, and recyclability make it an excellent material option for die-casting strong but lightweight components. Magnesium alloys are 33% lighter than aluminum and 75% lighter than steel with excellent strength-to-weight ratio.

Q: How strong is cast magnesium?

A: Magnesium casting proof stress is typically 75–200 mpa, tensile strength 135–285 mpa and elongation 2–10%.

Q: What should we do if we receive defective products?

A: If you receive defective product, please send us the photos, we will feedback to our engineers and qc departments, and solve the problems asap.

Q: How to pack the moulds and products?

A: For moulds, we will be coated one-layer anti-rust oil first, and then also will be covered thin films on the mould.Finally pack into fumigation wooden case.And as to products, we will pack into standard export cartons or as per customer's request to pack.

Q: How to avoid mass order quality problems?

A: Strengthen the prevention and inspection in advance of the process of production and processing, set important processes as the key point of quality control, follow up the inspection and defense throughout the process.
