KAINGKA Tech Industrial Limited is a professional forged heat sink manufacturer specializing in cold forged heat sink solutions for demanding thermal management applications. With over 15 years of manufacturing experience, we provide custom forged Heat Sink design and production for global customers in electronics, EV, telecom, LED lighting, and energy industries.
Our aluminum cold forged Heat Sink products deliver superior thermal conductivity, precision structure, and long-term reliability compared with traditional extrusion or die casting solutions.
A cold forged heat sink is a thermal management component produced through a high-pressure forging process performed at room temperature.
Unlike extrusion or casting, cold forging compresses aluminum material under extreme pressure, creating:
Higher material density
Improved thermal conductivity
Enhanced mechanical strength
Complex fin structures with tight tolerances
Because the aluminum grain structure remains continuous and compact, a high conductivity forged heat sink achieves more efficient heat transfer and longer service life.
Cold forging is widely used for applications requiring high performance passive cooling.
As an experienced forged heat sink supplier, KAINGKA Tech follows strict manufacturing procedures:
We use premium aluminum alloys including:
AL1070 – Maximum thermal conductivity
AL6063 – Balanced thermal and mechanical performance
AL6061 – High strength structural applications
Aluminum billets are compressed using precision hydraulic presses and custom molds, forming dense and accurate heat sink structures.
CNC milling & drilling
Surface finishing
Tight tolerance machining
Anodizing (black, silver, colored)
Sandblasting
Chemical conversion coating
Custom industrial coatings
Each precision forged heat sink undergoes dimensional inspection, thermal validation, and surface quality control to ensure stable performance.
High Thermal Conductivity
Dense aluminum structure improves heat transfer efficiency.
Complex Fin Geometry
Cold forging enables thin fins and optimized airflow design.
