Cold Forging Heat Sink Parts

KAINGKA Tech Industrial Limited is a trusted manufacturer of Cold Forging Heat Sink Parts, providing custom solutions for thermal management in EVs, LEDs, industrial equipment, telecom, and energy storage systems. Using advanced cold forging technology, we deliver heat sink parts with high precision, excellent thermal performance, and mechanical durability.

1. What Are Cold Forging Heat Sink Parts?

Cold forging heat sink parts are made through a high-pressure forging process at room temperature. Unlike die casting or extrusion, cold forging compresses aluminum to form dense, high-conductivity structures that enhance heat dissipation efficiency. The result is a precision aluminum heat sink with robust strength and optimal thermal conductivity, suitable for high-demand applications.

2. How Are Cold Forging Heat Sink Parts Made?

• Material selection: High-conductivity aluminum (e.g., AL 1070, 6063, 6061)

• Cold forging process: Aluminum billet is compressed in a custom mold using a hydraulic press

• Post-processing: CNC machining, anodizing, sandblasting, surface coating

• Inspection: Precision measurements, thermal simulation, and surface quality control

KAINGKA Tech uses advanced machinery and in-house die design to ensure precise production and stable performance.

3. Applications of Cold Forging Heat Sink Parts

Our cold forged heat sinks are widely used in:

• LED lighting systems

• 5G communication devices

• Electric vehicle power modules

• Battery energy storage systems (ESS)

• Solar inverter systems
