OEM Aluminum Heat Sink Production

Aluminum heat sinks are important components in thermal management systems and are widely used in industries such as electronics, communications, automobiles, and industrial machinery. The main function of a heat sink is to dissipate the heat generated by electronic components such as processors, LED lights, or power supplies, thereby improving the efficiency and service life of these devices.

KingKa specializes in OEM production of high-quality aluminum heat sinks. Through advanced CNC equipment and strict quality control, KingKa is able to provide customized high-precision aluminum heat sinks to meet specific heat dissipation needs.

CNC Equipment and Manufacturing Process

The production of aluminum heat sinks requires the use of dedicated CNC machining equipment to achieve the required high-precision performance. KingKa is equipped with the following advanced equipment:

CNC milling machine: used for the preliminary processing of the heat sink to ensure the accuracy of aluminum cutting and meet dimensional requirements.

CNC lathe: used to produce heat sinks with cylindrical or circular geometries.

CNC drilling machine: used to process holes and notches on the heat sink to improve heat dissipation efficiency and ensure compatibility with other components.

CNC machining center: capable of completing complex machining operations such as precision debugging, engraving, and surface treatment on the same equipment.

Wire EDM: For machining fine details and high-precision cutting, especially for thicker aluminum sections.

Materials

The aluminum used in the production of aluminum heat sinks is usually high-quality alloys such as 6063, 6061 or 1050. These alloys have the following characteristics:

High thermal conductivity: Aluminum can absorb and dissipate heat efficiently, effectively improving the thermal performance of the heat sink.

Lightweight: Aluminum is lightweight and suitable for weight-critical applications such as aerospace or automotive.

Corrosion resistance: Aluminum naturally forms a protective oxide layer, which enhances corrosion resistance and prolongs service life.

Different aluminum alloys are selected based on the thermal conductivity, strength and weight requirements required for the heat sink. For example, 6063 alloy is often used in extrusion processes due to its good surface effect and strength, while 6061 alloy is used in applications with higher requirements for strength and corrosion resistance.

Precision and tolerances

KingKa produces aluminum heat sinks with a high degree of precision to ensure their good fit and performance. The standard tolerance of CNC machined aluminum parts is usually between ±0.1mm and ±0.01mm, depending on the complexity of the design.

To ensure accuracy, KingKa strictly adheres to the following standards:

Dimensional tolerance: Ensure that the physical dimensions (length, width, height) of the part meet the specified tolerance requirements.

Surface roughness: The surface roughness is strictly controlled during the machining process, usually ranging from 0.8μm to 3.2μm, depending on the desired surface effect.

Surface treatment

Surface treatment is essential to improve the performance and appearance of the heat sink. KingKa offers a variety of surface treatment options, including:

Anodizing: This process forms a hard protective oxide layer on the surface of the aluminum, which not only improves the corrosion resistance of the aluminum, but also gives the heat sink a matte or shiny surface effect. Anodizing can also improve heat dissipation performance.

Powder coating: Powder coating provides a durable coloring effect that resists fading, scratching and peeling, while also enhancing corrosion protection.

Brushed or polished surface: This treatment makes the aluminum heat sink surface smooth and flat, suitable for applications that require high appearance quality, such as consumer electronics.

Optimized applications and features

Aluminum heat sinks have multiple advantages in electronics and other industries, and are widely used in various heat dissipation needs:

Effective heat dissipation: By increasing the surface area of the heat sink and the thermal conductivity of aluminum, aluminum heat sinks can quickly absorb and effectively disperse heat.

Lightweight: Compared with copper, aluminum is lighter and suitable for applications that require lightness.

Customized design: With the help of CNC technology, heat sinks can be customized according to specific size, shape and configuration requirements to meet the heat dissipation needs of different devices.

High cost performance: The cost of aluminum is relatively low, especially compared to copper, and it can still provide excellent heat dissipation.
