| High-Density Fin Heat Sinks | Straight-fin structures for forced-air cooling in server, power, and communication equipment. |
| Integrated Cooling Modules | Heat sinks made around fans, brackets, housings, and equipment interfaces. |
| Custom Machined Heat Sinks | Drawing-based mounting faces, holes, component pockets, and connection features. |
For suitable quantities and geometry, extrusion forms the main thermal profile with consistent fins and efficient material use. CNC machining completes the contact surfaces and assembly features.
Machined prototypes can support initial fit and thermal validation before extrusion tooling or larger production quantities are confirmed.
| Fin & Base Geometry | Custom fin layout, base thickness, and overall envelope. |
| Contact & Mounting Features | Flat contact surfaces, machined mounting faces, and component pockets. |
| Holes, Threads & Cutouts | Drilling, tapping, steps, and slots for installation and assembly. |
| Equipment Interfaces | Connector, fan, and housing interfaces reviewed with the available space and airflow direction. |
| 01 | Drawing Review | Confirm material, dimensions, tolerances, finish, and quantity. |
| 02 | Prototype | Produce samples for customer installation, appearance, and thermal validation. |
| 03 | Production | Extrusion, cutting, and precision CNC secondary machining. |
| 04 | Inspection | In-process and final checks of critical features, fin and surface quality, and shipment requirements. |
| 6063 Aluminum Commonly selected for extruded heat sink profiles where extrusion performance, fin geometry, thermal conductivity, and surface quality are important. | 6061 Aluminum Used for machined bases and structural heat sink components with strength and mechanical feature requirements. |
Final alloy selection considers heat dissipation, strength, size, finishing, and cost requirements.
| CNC Tolerances | Tolerances as tight as ±0.01 mm may be achievable on selected machined features, subject to drawing, geometry, and material review. |
| Typical CNC Samples | 5–10 days, with the schedule confirmed according to material, machining, finish, and quantity. |
| OEM / ODM Support | Drawing-based manufacturing, with CNC prototypes from one piece and support for repeat production. Extrusion tooling and quantities are reviewed per project. |
We can supply heat sinks together with brackets, panels, housings, frames, and other metal parts used in server and data center equipment.
| Aluminum Extrusion | Custom thermal profiles, housings, and structural sections. |
| 3/4/5-Axis CNC | Milling, drilling, tapping, turning, and precision secondary machining. |
| Sheet Metal Fabrication | Laser cutting, bending, server enclosures, and panels. |
| Metal Stamping | Custom brackets, covers, contacts, and production metal parts. |
| Welding & Assembly | TIG, MIG, and robotic welding for frames and assemblies. |
| Surface Finishing | Anodizing, powder coating, electroplating, and specified finishes. |
| AI servers | GPU systems |
| Data centers | HPC equipment |
| Server power supplies | Telecommunications |
| Power electronics | Energy storage |
| Industrial automation | Semiconductor equipment |
