Vansim (Dongguan)Hardware Products Co., Ltd.
- The material of heat sink base choosing: Used to be the material of AL6063.
- Heat Pipe Preprocessing: Clean and inspect heat pipes, and perform vacuum charging with working fluid (e.g., water).
- Extrusion Molding: Make a extrusion tooling to produce the extrusion profile,
- Cooling and Demolding: Cool the extruded part to solidify it, then remove it from the mold.
- Post-Processing:
- Cut to size and shape (e.g., fin height, length).
- CNC machining the heat pipes slots,
- Cleaning the heat sink base combined with the pipe slots,
- Stamping the heat pipes into the slots, The key point is to make sure the surface of the pipes be the same with the base.

- CNC machining the structure and surface,
- Surface treatment (e.g., passivating treatment, It has copper tube, So it can't to make the surface treatment of anodizing) to improve heat dissipation and corrosion resistance.
- Quality Inspection: Check for defects (e.g., heat pipe bonding, structural integrity) via visual inspection or thermal testing.
- Assembly (if needed): Attach additional components (e.g., fans, mounting brackets) based on application requirements.
- Final Packaging: Clean, package, and prepare for shipment.
