This aluminum heat sink is manufactured from 6063 aluminum alloy using precision CNC milling. Its long-strip structure and densely arranged cooling fins provide an enlarged heat-dissipation area, helping transfer heat away from electronic components efficiently.
The cooling fins are integrally machined to maintain consistent dimensions and structural accuracy. With machining tolerance controlled to ±0.05mm, the heat sink is suitable for electronic assemblies where accurate fitting and reliable thermal management are important.
Precisely positioned mounting holes on the end face make installation easier and support stable assembly with other components.
The heat sink can be finished with anodizing or sandblasting according to application requirements. These surface treatments can improve surface hardness, oxidation resistance, and corrosion resistance.
This CNC machined aluminum heat sink is widely used for industrial power supplies, power modules, communication equipment, communication base stations, industrial-control motherboards, and drive units.
As an experienced Aluminum Heat Sink Manufacturer, we also provide non-standard custom manufacturing according to customer drawings or samples.
The cooling performance of a heat sink depends heavily on its fin structure and available heat-dissipation area.
This long-strip heat sink features dense, evenly arranged cooling fins that increase the effective surface area available for heat transfer. The larger contact area allows heat to dissipate more efficiently into the surrounding environment.
The fins are integrally formed through CNC milling, helping maintain consistent spacing and dimensions across the heat sink.
This structure is suitable for electronic devices that generate continuous heat during operation, including:
Power Modules
Industrial Power Supplies
Drive Units
Communication Equipment
Industrial Control Electronics
Electronic Modules
By providing an efficient path for heat transfer, the heat sink can help reduce the operating temperature of electronic components and improve system stability.
Precision machining is important when a heat sink needs to fit accurately into an electronic or mechanical assembly.
This CNC aluminum heat sink is manufactured using CNC milling technology, with the overall machining tolerance controlled to ±0.05mm according to the specified requirements.
The CNC machining process allows important features such as:
Cooling fins
Mounting holes
End-face dimensions
Overall length
Width and height
Component mounting surfaces
to be manufactured according to customer drawings.
Precisely positioned mounting holes on the end face make installation easier and help achieve accurate fitting with the customer's equipment.
For custom projects requiring specific dimensions or mounting configurations, our Custom CNC Machining Service can manufacture non-standard heat sinks based on technical drawings or samples.
The heat sink is manufactured from 6063 aluminum alloy, a lightweight aluminum material commonly used for heat-dissipation components and profiles.
The material provides a combination of thermal performance, low weight, machinability, and surface finishing capability.
The lightweight construction is particularly useful for electronic equipment where reducing component weight is important.
Key advantages include:
Good thermal conductivity
Lightweight construction
Good machinability
Suitable surface finishing performance
Good corrosion resistance after appropriate surface treatment
Suitable for precision heat-dissipation components
The material specification can be confirmed according to the customer's project requirements before production.
Different applications may require different surface finishes.
We provide anodizing and sandblasting options for this aluminum heat sink.
Anodizing can improve the surface hardness and oxidation resistance of aluminum components while providing a more uniform surface appearance.
It is suitable for applications where surface durability and corrosion resistance are important.
Sandblasting creates a uniform matte surface finish and can improve the overall appearance of the machined aluminum component.
The appropriate surface treatment can be selected according to the application environment and customer's requirements.
This long-strip aluminum heat sink is designed for electronic and industrial equipment that requires effective thermal management.
The heat sink can be installed on power modules to help transfer heat generated during operation and maintain a more stable working temperature.
It is suitable for communication equipment and communication base stations where electronic components may generate continuous heat.
The heat sink can be used with industrial-control motherboards, drive units, and other industrial electronic modules.
Power supply components can generate considerable heat during continuous operation. A properly designed aluminum heat sink helps provide an efficient heat-transfer path.
Standard heat sinks may not always match the dimensions or mounting requirements of a customer's equipment.
We provide Custom Aluminum Heat Sink Manufacturer services for non-standard heat-dissipation components based on customer drawings or samples.

Dimensional consistency is important for heat sinks used in precision electronic assemblies.
Each finished component undergoes inspection before shipment. Key dimensions and mounting features are checked against the approved drawing or technical specifications.
The inspection process focuses on:
Overall dimensions
Mounting hole position
Mounting hole size
Cooling fin dimensions
Surface condition
Machining tolerance
Surface treatment
The specified machining tolerance is ±0.05mm, subject to the actual feature and drawing requirements.
Inspection requirements for OEM projects can also be discussed before production.
Aluminum heat sinks with machined or finished surfaces need appropriate protection during transportation to prevent scratches, moisture, and collision damage.
The standard packaging method includes:
Pearl Cotton + Anti-Rust Bag + Export Carton
Individual pearl cotton protection helps separate the machined components and reduce surface-to-surface contact during transportation.
An anti-rust bag provides additional protection against moisture during storage and shipping.
For larger orders or special transportation requirements, customized packaging solutions can also be discussed.
