Forged Heat Sink Manufacturer
Single-piece aluminum and copper forged heat sinks with dense pin fins, compact geometry, flexible airflow, and reliable production.
High-Density Single-Piece Forged Heat Sinks
Forged heat sinks are formed by applying high pressure to an aluminum or copper billet, forcing the material into a precision tool that creates the base and fins as one continuous component.
Cold forging is particularly suited to pin-fin, elliptical-fin, radial, and other compact three-dimensional fin structures. Because the base and fins are formed from a single piece of metal, there is no adhesive or solder joint between them.
The process can produce dense pin arrays with good dimensional repeatability, mechanical strength, and thermal continuity. Forged pin-fin designs are also useful where airflow direction may vary or where air enters from above rather than moving through a single straight channel.
Advantages of Forged Heat Sinks
One-Piece Construction
The fins and base are integral, reducing thermal interfaces and providing a strong, durable structure.
Compact Pin-Fin Geometry
Round, square, elliptical, or custom pins provide substantial surface area within a compact footprint.
Flexible Airflow Direction
Pin-fin arrays allow air to travel through the heat sink from several directions, which can be useful in compact or variable-airflow systems.
Aluminum and Copper Options
Aluminum provides a practical balance of weight, conductivity, and cost. Copper can be considered when improved heat spreading is more important than weight.
Repeatable Production
After tooling approval, forging supports stable production with consistent fin geometry and limited assembly work.

Our Custom Forging and Machining Capabilities
At XINXIANG, we manufacture custom forged heat sinks from your drawings, thermal requirements, or existing product samples.
Custom Pin and Fin Design
We can evaluate round pins, square pins, elliptical pins, radial fins, and other forged structures according to the cooling method and available space. Elliptical pin structures can be useful where lower pressure drop is required in a defined airflow direction, while round pins are suitable for more multidirectional airflow.
CNC Secondary Operations
After forging, heat sinks can be machined with component pockets, mounting holes, threads, slots, flat contact surfaces, fan mounts, and assembly features.
Surface Treatment
Aluminum forged heat sinks can be supplied with clear or black anodizing and other project-specific finishes. Copper parts can receive anti-oxidation treatment or nickel plating.
Fan and Hardware Assembly
Fans, brackets, push pins, spring screws, clips, thermal interface materials, and mounting plates can be supplied as a complete assembly.
We help you every step of the way, from drawings to production.
Application Review
Send us your drawing, material preference, quantity, and finish requirement.
Design and DFM
We review fin density, airflow resistance, base spreading, mounting, tolerances, and machining access.
Prototype & Production
Produce samples for dimensional, assembly, and thermal evaluation. Then complete volume production under controlled work instructions once we receive your confirmation.
Inspection and Delivery
Inspect the parts, protect the fins from damage, pack for export, and ship worldwide.
With more than 20 years of heat sink manufacturing experience, XINXIANG supports international OEMs and industrial buyers from early design review through repeat production. Our 6,000 m² facility combines multiple thermal manufacturing processes with CNC machining, finishing, inspection, assembly, and export packaging.

Common Questions from Our Clients
What is the difference between forged and skived heat sinks?
Forged heat sinks commonly use pin-fin, radial, or three-dimensional structures formed under pressure. Skived heat sinks use thin plate fins cut and lifted from a solid block. Skiving usually offers very thin, closely spaced straight fins, while forging is especially useful for compact pin arrays and multidirectional airflow.
Are forged heat sinks suitable for natural convection?
Yes. Pin-fin and radial designs are frequently used in natural-convection applications, but the final geometry must be matched to orientation, available space, heat load, and ambient conditions.
Can you forge copper heat sinks?
Copper forging can be evaluated for projects requiring improved heat spreading. Copper parts are heavier and generally more expensive than aluminum parts.
Is custom tooling required?
Yes, custom forged geometries normally require dedicated tooling. Tooling cost is most easily justified for repeat or volume production.
Can forged heat sinks be CNC machined?
Yes. Mounting surfaces, holes, threads, pockets, and assembly features can be machined after forging.
Can you do door-to-door shipping?
Yes, we can. We work with several reliable freight forwarders and can arrange door-to-door shipping to most countries — just let us know your delivery address.
We can also use your freight forwarder if you have one.
