• 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.
