ALU Die Casting – The Top Heat Sink Manufacturer in China

GC Precision Mould Co., Ltd is one of the known heat sink manufacturers in China. ALU’s method is ideally fit for making complex and detailed aluminum heat sinks. Here, die casting includes injecting molten aluminum into a steel mold (die). It then applies high pressure. After that, it solidifies to form the desired shape. Therefore, this technique plays a significant role in the production of parts. It gives high dimensional accuracy and superior surface finishes. So, it is perfect for intricate heat sink designs.

Step-by-Step Process Heat Sink Manufacturing at ALU Die Casting

So, here is a detailed process of  Heat Sink Manufacturing at AL Die Casting.

1. Design Phase

This process starts with a comprehensive thermal analysis. It helps understand heat dissipation needs. After that modern simulation techniques and calculations help increase the efficiency of heat sinks. So, it can manage thermal loads effectively. Just after that, we select the material, i.e. Aluminum so it can balance high thermal conductivity, lightweight nature, and structural integrity. Additionally, the aluminum alloys further increase the performance and durability of the heat sinks.

The size and shape considerations for heat sink manufacturing are equally important. They help meet the specific form and thermal demands of any project. Besides this, they help optimize the surface area for heat dissipation.

Additionally, this selection helps increase the performance and longevity of the product. So, after this, the raw aluminum is precisely cut. We provide them with shapes using our modern CNC machining and extrusion techniques. So, they can meet the design specifications, effectively.

3. Die Casting Process

This stage plays a very significant role in heat sink manufacturing.

  • Injection of Molten Aluminium: It starts with injecting the molten aluminum into the die under high pressure. This gives heat sinks an optimal surface finish with accurate cross-sectional geometry. So, it can increase heat transfer rates.
  • Cooling and Solidification: The molten metal turns into a solid mass within the die. Here it makes the impressions of the required shape. So, cooling systems make it possible to stabilize and firmly solidify the cast parts. In the end, the molten metal is poured into the metal again.
  • Trimming and Finishing: Excess material is removed and heat sinks are surfaced and finished with secondary operations to the required tolerances.

4. Surface Treatment

At this stage, the heat undergoes the following processes.

  • Anodization: When the heat sink is allowed to go through anodization, its thermal performance and corrosion resistivity increase. Additionally, it also plays an important role in enhancing the aesthetics of the heat sink.
  • Coating: After anodization, heat sinks may undergo a coating process. It helps protect their surface from environmental conditions and mechanical wear as well. Besides this, it also enhances the heat sink’s appearance.

5. Quality Assurance and Testing

Once the ALU die casting is done with all operations. We cater to the quality assurance and testing of the products. Our services include testing the thermal performance testing. It guarantees high standards and meets the required heat dissipation. Additionally, we also deal with thermal resistance and cooling efficiency. So, let’s discuss all these in detail
