Why Choose Custom Heat Sinks?

A heat sink is a passive cooling device that absorbs and dissipates heat from electronic or mechanical systems, preventing overheating and extending component life. Custom heat sinks offer tailored designs optimized for your specific thermal profile, outperforming standard solutions by improving efficiency, minimizing size and weight, and addressing unique environmental challenges.
Key Benefits of Customization:
Enhanced Thermal Performance: Achieve up to 25-35% lower operating temperatures with optimized fin geometry and material selection.
Compact Designs: Tailored shapes fit constrained spaces without sacrificing cooling capacity.
Cost Efficiency: Streamlined production reduces material waste and overall costs.
Application-Specific Solutions: Meet stringent requirements for industries like aerospace, automotive, and high-performance computing.
Our Custom Heat Sink Types
XTJ Precision Mfg offers a wide range of custom heat sink types, each crafted with precision to suit your application’s needs:

Custom Vapor Chamber Heat Sink
A planar heat pipe that spreads heat uniformly across its surface, creating an isothermal base. Perfect for applications with concentrated heat sources, such as high-performance computing or LED systems.

Machined Custom Heat Sink
Utilizing our advanced CNC machining capabilities, we produce heat sinks with complex features, contours, cut-outs, and through-holes. Low setup costs make this ideal for low to medium volumes, with tolerances as tight as ±0.005mm.

Custom Extruded Heat Sink
Aluminum extrusions provide a cost-effective solution for high-volume production. Uniform fin profiles ensure efficient airflow, suitable for electronics and automotive applications.

Custom Casted Heat Sink
Using investment casting, we create complex heat sink designs quickly and affordably. This process is perfect for prototypes and short to medium production runs, delivering intricate shapes with high precision.

Custom Die-Cast Heat Sink
Our proprietary high-thermal-conductivity aluminum alloy (~160 W/mK) enables cost-effective die-casting for medium to large production volumes. Ideal for rugged applications requiring consistent performance.

Custom Skived Heat Sink
A controlled shaving technique creates high-density, thin-fin heat sinks from a single block of aluminum or copper. This method ensures uniform fins and excellent thermal performance in compact spaces.

Custom Stamped Fin Heat Sink
Stamped from sheets of aluminum or copper, these heat sinks offer flexible fin geometries and thicknesses. Perfect for medium to high-volume production with customized designs for specific airflow needs.

Custom Heat Pipe Heat Sink
A vacuum-sealed copper tube filled with a working fluid (e.g., water) rapidly transfers heat to cooler regions with minimal temperature rise. Ideal for high-heat-flux applications like CPUs, GPUs, and power electronics.
Complex 3D Geometries
Fully bespoke designs with integrated features like mounting holes or embedded heat pipes.
Best Material Options for Custom Heat Sinks
Lightweight (2.7 g/cm³), high thermal conductivity (205-250 W/mK), and cost-effective. Ideal for electronics, automotive, and consumer devices.

Exceptional conductivity (385-401 W/mK) for high-heat applications, such as data centers and industrial equipment.

Aluminum-silicon or copper-tungsten composites for enhanced strength, thermal expansion matching, or corrosion resistance.
