Aluminum Die Casting | NVIDIA GPU Frame Manufacturer

NVIDIA is a prominent player in the graphics card industry, known for its cutting-edge technology and high-performance GPUs. In this blog, we will explore the specific requirements for aluminum die casting in GEFORCE series graphics card brackets, addressing challenges faced in design iteration, die casting material selection, streamlining production, and surface treatment. By understanding these aspects, buyers and part design engineers can make informed decisions when seeking custom aluminum die cast manufacturers or services.

NVIDIA's Position in the Graphics Card Industry:

NVIDIA has established itself as a leading manufacturer of graphics processing units (GPUs), delivering unparalleled performance and advanced features. Their GPUs power various applications, including gaming, artificial intelligence, and data analysis. As demand for high-quality graphics cards continues to rise, the need for reliable and efficient manufacturing processes becomes crucial.

The Functions of Aluminum die cast GPU Frame

Aluminum die castings can be seen everywhere in our life. Aluminum die cast GPU frames serve several important functions in computer systems. Here are some key functions of aluminum GPU frame and aluminum die castings:

Structural Support:

One of the primary functions of an aluminum die cast GPU frame is to provide structural support and rigidity to the graphics processing unit (GPU) and its surrounding components. The frame helps to hold the GPU securely in place, preventing any unnecessary movement or vibrations that could potentially damage the GPU or other components.

Heat Dissipation:

Aluminum is an excellent conductor of heat, and GPU frames made from this material can help dissipate heat generated by the GPU during operation. The frame acts as a heatsink, absorbing and dispersing the heat away from the GPU and into the surrounding air. This helps maintain optimal operating temperatures for the GPU, preventing overheating and potential performance issues.

EMI Shielding:

Aluminum is also known for its electromagnetic interference (EMI) shielding properties. GPU frames made from aluminum can help contain and reduce electromagnetic radiation emitted by the GPU. This shielding function is crucial for maintaining signal integrity and minimizing potential interference with other electronic components within the computer system.

Component Organization and Protection

GPU frames often include various mounting points and brackets that help organize and secure other components such as fans, cooling systems, and cables. This organization ensures proper alignment and installation of these components, reducing the risk of damage and optimizing system performance.

Aesthetic Appeal

In addition to their functional benefits, aluminum die cast GPU frames often have an aesthetically pleasing design. They can add a visually appealing element to the computer system, enhancing its overall look and feel.

Requirements for Aluminum Die Casting manufacturers in manufacturing GPUs Frame

Neway has demonstrated the following strengths in the manufacturing process of aluminum die cast GPUs frames.

Expertise in Aluminum Die Cast Parts

It is essential to have expertise and experience in aluminum die casting processes specifically for manufacturing GPU frames. This includes knowledge of die casting techniques, tooling, mold design, and finishing processes required for producing high-quality GPU frames. And the ability to solve common problems of aluminum die casting products.

Manufacturing Facilities

Aluminum die casting manufacturer would need manufacturing facilities equipped with the necessary machinery and equipment for aluminum die casting. This includes die casting machines, molds, melting furnaces, trimming and finishing tools, and quality control equipment. This will be the basis of all aluminum die casting processes。

Material Selection and Sourcing

Choose suitable aluminum alloys for die casting GPU frames, such as ADC12 or A380, which offer the desired strength, heat dissipation properties, and dimensional stability. Establish reliable supply chains and partnerships with reputable aluminum raw material suppliers to ensure a consistent and high-quality source of materials. This will be a compulsory course for all aluminum die casting manufacturers

Design Capabilities

Collaborate with GPU manufacturers or have in-house design capabilities to understand the specific requirements and dimensions of the GPU frames. Adapt to changes in GPU designs and optimize the frame design for thermal management and compatibility. The design ability and feasibility evaluation of aluminum die casting parts are very important. The aluminum die casting manufacturer should actively communicate with customers and give the most feasible production plan.

Quality Control Systems

Implement robust quality control systems to ensure that the produced GPU frames meet the required specifications and standards. Aluminum die casting manufacturers should conduct inspections and tests throughout the manufacturing process to check for dimensional accuracy, surface finish, strength, and other performance criteria.

Compliance and Certification

Adhere to industry standards, regulations, and certifications. This includes compliance with environmental regulations, such as waste management and recycling, and obtaining certifications like ISO 9001 for quality management systems.

Collaboration and Partnerships

Establish strong relationships and partnerships with GPU manufacturers. Collaborate closely with them to ensure a deep understanding of their requirements and enable efficient production processes.

Capacity and Scalability

Assess your manufacturing capacity and scalability to meet the demands of GPU manufacturers. Consider factors such as production volume, lead times, and the ability to scale up or down production based on market requirements.

By meeting these requirements, you can be a reliable and capable aluminum die casting manufacturer for GPU frames. Continuous improvement, staying updated on industry trends, and investing in research and development can help you remain competitive in the market.

Challenges in Die Casting GPU frames

In the process of cooperating with Nvidia, Neway encountered the following challenges, and solved the heat dissipation problem of aluminum die-casting GPUs frame, the problem of continuous work under thermal conditions, the problem of die-casting thin-wall accuracy, and the high-complexity design drawings multiple iterations that not suit for manufacturing anymore.

Neway Free Manufacturing Drawings Redesign

Nvidia's design team performed multiple design iterations on the GPU frame to meet the maximum mounting requirements. This results in parts that are already highly complex and cannot be mass-produced at all. Neway communicated with Nvidia's designers to redesign the drawings and retain all functional features. This makes the design possible for mass production. You must know that most designers do not understand the manufacturing process, and Neway has demonstrated strong production design capabilities here. Neway's production design engineer communicated with NVIDIA's design team and put forward a design proposal suitable for production. Finally, with the efforts of both parties, the design of the final production drawings was completed.

Die casting material customization

Die-cast aluminum alloy has good heat dissipation performance like other aluminum alloys, but in order to improve the aesthetics and durability, the aluminum die-cast GPU frame needs to be hard anodized. Strictly speaking, die-cast aluminum alloys are generally not suitable for anodizing. Neway, through its strong raw material supply chain, has customized the die-cast aluminum to meet both die-cast conditions and hard anodizing.

Post-machining of die-casting thin walls

Die casting is a method of obtaining final die castings by cooling molten metal in a mold. And this method has a natural defect, that is, thermal expansion and contraction. When the part cools, there will be a small shrinkage. For thicker walls, this shrinkage is not easy to find, but for thin walls, this shrinkage will crack or deform the thin wall.

Neway thickens the thin wall and then performs secondary CNC machining to complete the final thin wall size and precision.
