22 Years of Expertise as a Custom Heat Sink Manufacturer
Leveraging 22 years of engineering and manufacturing expertise, we specialize in solving complex heat dissipation challenges through customized thermal solutions. Our core competency lies in serving high-demand sectors, including Aerospace, Military, Marine, Rail Transit, Power Electronics, AI Data Centers, and IGBT/Inverters.
Whether your project requires our engineering team to provide rapid thermal simulation (CFD) and design optimization for a bespoke cooling module, or you need accurate build-to-print manufacturing strictly based on your technical drawings, we deliver reliable execution from prototyping to mass production.
Technologies for Custom Heat Sinks
Liquid Cold Plate
Engineered for extreme heat flux and high-power applications (e.g., AI servers, EV batteries). We provide multiple fabrication processes, including Friction Stir Welding (FSW) for large-scale robust sealing, Vacuum Brazing for complex micro-channels, and cost-effective Tube Embedding, ensuring reliable, leak-free performance.Skived Heat Sinks
Machined from a single block of copper or aluminum, providing zero interface thermal resistance and ultra-high fin density. We are capable of producing large-format skived fins up to 900mm × 3000mm.Vapor Chamber Heat Sink
Utilizes phase-change technology (including 2D and 3D VC structures) for rapid and uniform heat spreading, effectively eliminating concentrated hot spots in compact, high-power electronics.Heatpipe Cooling Module
Integrates sintered copper heat pipes with aluminum or copper fin stacks via precise reflow soldering, delivering rapid directional thermal transfer for high-TDP components.Cold Forging Heat Sink
Manufactured via high-pressure cold forging using high-purity aluminum (e.g., AL1070) or copper. It creates dense pin-fin structures with superior thermal conductivity compared to standard die casting.Zippered Fin Heat Sink
Features a lightweight, interlocking fin structure that maximizes the surface area-to-weight ratio. Commonly assembled with heat pipes or vapor chambers for forced convection cooling systems.Custom Folded Fin
Formed by folding continuous metal sheets to maximize cooling surface area within strictly constrained volumetric limits, ideal for restricted airflow channels.Extrusion Heat Sink
A highly cost-effective and reliable manufacturing method for producing continuous linear fin profiles, widely adopted in standard industrial thermal management.Stamping Parts
Precision stamped metal components, brackets, and base plates manufactured with tight CNC tolerances, suitable for high-volume structural mounting and assembly.
From Custom Heat Sink Design to Mass Production
Whether you have mature CAD drawings or just a thermal concept, our engineering team provides end-to-end support. Your intellectual property is our priority; we are fully prepared to sign a Non-Disclosure Agreement (NDA) before proceeding.
Step 1: Thermal Requirements & Custom Heat Sink Design Input
To engineer the optimal custom cooling solution, our thermal experts need your system’s critical parameters:
Dimensional Constraints: Max Length, Width, and Height for the custom heatsink profile.
Heat Source Data: Physical size of the chip and Thermal Design Power (TDP / Watts).
Thermal Limits: Ambient temperature and Maximum allowable junction temperature (
Tj).Cooling Method: Natural convection, forced air, or custom liquid cold plate requirements.
Step 2: CFD Thermal Simulation & Design Optimization
Using advanced software like Flotherm and ANSYS Icepak, we validate your custom heat sink design. We run rigorous thermal simulations to ensure the theoretical performance of your tailored heat sink meets the exact specifications before any metal is cut.
Step 3: DFM Analysis & Rapid Prototyping
A flawless custom heat sink design must also be cost-effective to produce.Once approved, we move to rapid prototyping using CNC machining or skiving, delivering functional samples for your physical testing.
Step 4:Mass Production & Quality Control
Once the custom heatsink prototype is validated, we scale up to mass production. Every batch undergoes strict CMM dimensional checks and thermal performance testing to guarantee that the final custom thermal solution perfectly matches the approved design.
Frequently Asked Questions for Your Custom Heat Sink Project
Are you a trading company or a direct custom heatsink manufacturer?
We are a direct, ISO-certified custom heatsink manufacturer with our own production facility. By controlling the entire process from CNC machining and skiving to soldering and leak testing in-house, we guarantee strict quality control and competitive factory-direct pricing for your custom heat sink orders.
What is your Minimum Order Quantity (MOQ) for a custom heat sink?
We understand the engineering development cycle. Whether you need a single prototype to validate a custom heatsink design or 10,000 units for mass production, we support Low-Volume, High-Mix orders without rigid MOQ restrictions.
How fast can you prototype a custom heat sink design?
For processes that do not require hard tooling, such as CNC machining or skived fins, our engineers can transform your custom heatsink design into a functional, thermal-tested prototype in as fast as 3 to 7 working days after DFM approval.
Do you provide thermal simulation before manufacturing?
Yes. As a professional custom heatsink manufacturer, our engineering team uses advanced CFD software (like Flotherm) to analyze your custom heat sink concept. We optimize the fin pitch, base thickness, and material choice before cutting any metal, ensuring zero thermal failure.
