Our Products
Our manufacturing capabilities include aluminum extrusion, skiving, stamping, die casting, CNC machining, and assembly, allowing us to produce a wide range of standard and custom heat sinks for different thermal applications.
Extruded Heat Sink
Skived Heat Sink
Skiving from a solid metal block creates a one-piece, high-density fin array ideal for high-power or space-constrained cooling.Bonded Fin Heat Sink
Brazed or epoxied fins on a grooved base allow taller, denser fin structures, delivering superior cooling for high-power electronics.Die Cast Heat Sink
Complex aluminum heat sinks with integrated fins, housings, and mounting features. Ideal for cost-effective, consistent medium- to high-volume production.Forged Heat Sink
High-pressure forging yields a robust one-piece heat sink with dense pin fins for optimal cooling in compact, high-vibration applications.Liquid Cold Plate
Integrated liquid channels in a metal plate deliver superior heat removal for high-power applications beyond the capabilities of air cooling.Materials We Use
At XINXIANG, we manufacture heat sinks using both aluminum and copper to meet different thermal, structural, and budget requirements.
Aluminum is lightweight, corrosion-resistant, and cost-effective, making it ideal for most general-purpose cooling needs. Copper offers superior thermal conductivity and is preferred in high-performance or space-constrained applications.
We select the right material based on your project’s performance, environment, and cost priorities — ensuring optimal thermal management every time.
Copper for Peak Thermal Performance
Copper heat sink offers the highest thermal conductivity, ideal for compact, high-power applications where heat transfer efficiency is critical.
Aluminum for Lightweight Efficiency
Aluminum heat sink provides a perfect balance of conductivity, weight, and cost — widely used in extrusion and large-scale production.
Material Flexibility for Custom Solutions
Copper or aluminum — we choose the right metal for your budget, design needs, and thermal requirements.
Sustainable Metals. Greener Cooling.
Both aluminum and copper are fully recyclable, supporting eco-friendly production and reducing environmental impact in thermal management solutions.
Multiple Manufacturing Capabilities to Deliver Thermal Products
Within our 64,000 square foot production facility, our in-house processes include extruding aluminum profiles, skiving, metal stamping, die casting, CNC machining, and mechanical assembly.
Our manufacturing facility, together with an established network of qualified subcontractors and raw material suppliers, enables us to support a wide range of heat sink manufacturing processes.
Whether you require lightweight extruded heat sinks, high-density skived fins, precision-stamped bases, or fully assembled liquid cold plates, we have the technology and expertise to deliver.

What Our Clients Say
Common Questions from Our Clients
How long does it take to get a quote?
Usually within 24 hours. Send us your drawing or requirements — the more info you share, the faster we can quote accurately.
Do you have standard heat sink sizes, or are they all custom?
We offer both existing extrusion profiles and custom heat sinks made using different manufacturing processes.
If you’re looking for an extruded heat sink, browse our Heat Sink Extrusion Profiles to check available sizes and existing tooling.
What materials do you use for heat sinks?
Mostly aluminum and copper. We’ll help you pick the right one based on performance, weight, and cost.
Can you help with thermal design or selection?
Yes. Our team can review your specifications and suggest suitable materials, fin structures, or cooling methods based on your application.
Do you support small volume orders or prototypes?
We do. Whether you need 10 pieces or 10,000, we’re flexible. We also support prototyping for new designs. Send us your design and required quantity, and we will prepare a quotation.
What is your production lead time?
We maintain a large inventory of existing extrusion tooling, which can reduce tooling time and speed up production for suitable projects. That means we can sometimes skip the tooling stage and jump straight into production.
Production lead time is typically 1–4 weeks with existing tooling, depending on the product, quantity, machining, and finishing requirements.
For orders requiring a custom heat sink mold, tooling development and sample approval are usually required. We can also work on that quickly.
How do you pack the heat sinks?
We select suitable packaging according to the part size, fin density, quantity, and shipping method. Options may include protective trays, cartons, pallets, or wooden crates.
We can also follow your specified packaging requirements.
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.
