Aluminum Die Casting Manufacturer in China

Q: What about the lifespan of your die casting mold?

50,000 shots before replacement or refurbishment. If the old die-casting mold reaches the end of its service life, we can replicate a new mold for you

Q: What are the differences between cold chamber & hot chamber die casting? (Cold chamber die casting VS hot chamber die casting)

Cold Chamber Die Casting: This method is suitable for materials with higher melting points like aluminum and magnesium. The metal is melted in a separate furnace and then injected into the cold chamber machine. It's ideal for casting durable and lightweight parts but can be a bit slower due to the need for metal transfer. Hot Chamber Die Casting: Designed for materials with lower melting points, such as zinc. In this process, the metal remains in a molten state within an integrated furnace connected to the machine. Hot chamber die casting is faster and more efficient for casting smaller, intricate parts, making it cost-effective for high-volume production.

Aluminum High Pressure Die Casting Process Overview

How does die casting work? Aluminum die casting is a metal manufacturing method that involves heating aluminum alloy to a liquid state and injecting it into custom molds under high pressure. There are six major steps of how a die-cast part&component is made:

Mold design
Casting preparation
Injection
Cooling and solidfication
Demolding / removal
Usinage CNC / traitement de surface

Dive into the aluminum die casting processes below to get a further understanding.

Step 1

Aluminum Die Casting Mold Design

When designing the mold for your aluminum die casting project, we prioritize factors such as manufacturability and cost-efficiency. Our team provides DFM (Conception pour la fabricabilité) support, ensuring that the aluminium die casting mold is not only tailored to your desired part’s shape and dimensions but also optimized for efficient and cost-effective production. The mold is typically composed of two or more halves, facilitating the filling and removal process during casting.

Step 2

Casting Preparation

First, we heat the chosen aluminum alloy to its melting point while readying all necessary materials and equipment. Simultaneously, the injection machine is prepared for the molten aluminum alloy to be injected into the pre-designed mold.

Step 3

Injection

The molten aluminum alloy is then injected into the meticulously crafted mold, accompanied by the application of high pressure to ensure thorough cavity filling. After filling, a certain pressure is maintained to keep the aluminum alloy in a liquid state for a specific duration.

Step 4

Cooling and Solidification

As the aluminum alloy cools down, it solidifies and gradually takes on the desired shape within the mold. The cooling duration depends on both the aluminum alloy type and the part’s thickness.

Step 5

Demolding / Removal

Once the aluminum alloy is completely solidified, the mold is opened, and the finished parts are carefully extracted. Specialized equipment is often employed to facilitate this removal process.

Step 6

Usinage CNC / Surface Treatment

Depending on specific requirements, the finished parts may undergo additional processes (Usinage CNC & finishing services) like cutting, drilling, or coating to meet exacting standards.

Qu'est-ce que le moule de moulage sous pression?

Die casting mold, also known as a die, is a tool used in the die casting process to create metal parts with high precision and accuracy. The mold is a hollow cavity that is used to shape molten metal into a specific form through a process known as die casting. Die casting molds are typically made from steel and have two distinct halves that come together to form the desired shape of the final part. The mold is designed with intricate details and features to ensure that the final part meets the required specifications and tolerances. Die casting molds can be used repeatedly to produce large quantities of identical parts quickly and efficiently.

FAQs on Die Casting

What are the minimum tolerance requirements for certain precision aspects of the product? What is the minimum draft angle, and what about linear and angular tolerances?

The minimum tolerance requirements depend on the size of the product.

For dimensions up to 200mm, tolerances of ±0.1mm or better are required.

For dimensions up to 300mm, tolerances of ±0.2mm or better are necessary;

and for dimensions up to 500mm, tolerances of ±0.3mm or better are expected.

As for draft angles, a minimum of 1 degree is required, but larger angles are preferred for smoother ejection from the mold.
These tolerance specifications are essential to ensure the precision and quality of die-cast products.

What about the lifespan of your die casting mold?

50,000 photos avant remplacement ou remise à neuf. If the old die-casting mold reaches the end of its service life, we can replicate a new mold for you

What are the differences between cold chamber & hot chamber die casting? (Cold chamber die casting VS hot chamber die casting)

Moulage sous pression en chambre froide: This method is suitable for materials with higher melting points like aluminum and magnesium. The metal is melted in a separate furnace and then injected into the cold chamber machine. It’s ideal for casting durable and lightweight parts but can be a bit slower due to the need for metal transfer.

Hot Chamber Die Casting: Designed for materials with lower melting points, such as zinc. In this process, the metal remains in a molten state within an integrated furnace connected to the machine. Hot chamber die casting is faster and more efficient for casting smaller, intricate parts, making it cost-effective for high-volume production.

Why are your mold prices higher than those of most other factories?

Our mold prices are fair and reasonable, and we don’t aim to profit excessively from our customers on mold costs. Moreover, for customers with large order volumes, in the event that a mold becomes unusable, we offer the option of creating a new mold at no additional cost. Additionally, factors contributing to the pricing of molds include the strength and material selection in the mold design.

How do you handle sustainable practices in aluminum die casting?

Sustainability is a key consideration in our operations. We prioritize sustainable practices by minimizing waste, recycling materials, and implementing energy-efficient processes. Here at Bian, for the sake of material purity, our company utilizes a central melting furnace for the concentrated melting and refining of recycled materials before their reuse. We enforce strict control measures throughout the aluminum die casting process, including incoming raw material inspections, periodic testing of material composition every two hours, and regular third-party testing.

What certifications do you hold for quality assurance?

We hold several certifications that attest to our commitment to quality and adherence to industry standards. These certifications include ISO 9001 for quality management, OIN 14001 for environmental management, and IATF 16949, which is specific to the automotive industry. These certifications provide B2B clients with confidence in our processes and our ability to consistently deliver high-quality products.
