From die engineering to anodized finish — every step in-house, no handoffs.160–180W/m·K AA6063±0.1 mmTolerance2–4 wksDie lead timeAA6063-T5 / AA6061-T6 Die cost from USD $800 Type II / III Anodizing CNC Drilling & Tapping Powder Coating MIL-DTL-5541 Chromate Prototype from 50 pcs ISO 9001 CertifiedAluminum Heat Sink ExtrusionThe default choice for a reason. Here's what actually makes extrusion work.Most sourcing engineers have been down this road before. The tooling budget is tight, the thermal spec has two or three unknowns, and the schedule doesn't allow for a six-week die-cast tool. That's exactly where aluminum heat sink extrusion earns its place.A heated AA6063-T5 billet gets loaded into the press and forced through a precision-machined die. What comes out is a continuous profile — same cross-section, every single piece, across tens of thousands of units. Cut to length, CNC-drill the mounting holes, anodize the surface. Done. The repeatability isn't a talking point; it's baked into the physics of the process."Die tooling from $800. The same geometry, held to ±0.1 mm, for the life of the program."Where engineers get tripped up is treating extrusion as a commodity. Fin pitch selection matters — for natural convection, 6–8 mm spacing prevents boundary layer overlap; forced-air designs can push to 2–3 mm when airflow exceeds 2 m/s. Base thickness affects spreading resistance as much as conductivity does. These aren't decisions to leave to a die house; they're part of the thermal design.HTC handles the full cycle in-house: profile design review, die fabrication, extrusion, CNC secondary operations, and surface treatment — Type II, Type III hard anodizing, powder coating, MIL-DTL-5541 chromate conversion.

Stamping is where volume economics actually kick in.There's a category of thermal application where extrusion tooling is overkill and cold forging is expensive — low-to-mid dissipation loads, high annual volumes, tight BOM targets. That's the space stamped heat sinks were built for.The process is straightforward: sheet metal — typically AL 1XXX or 5XXX series — is fed through a progressive die and formed into the required geometry in a single continuous press cycle. No secondary operations needed for basic profiles. What you get is a thermally functional component at a unit cost that die casting or extrusion can't match once volumes climb past a certain threshold."Progressive die tooling means the same geometry, produced at speed, with consistent dimensional output across millions of cycles."HTC's stamping capability covers the full range: aluminum stamped heat sinks for consumer and industrial electronics, stamped metal components for enclosures and structural brackets, steel stamping parts for higher-load mechanical applications, and stamping die components for customers who need precision tooling manufactured to spec. Surface finish options are handled in-house — as customer requires, with OEM configurations available.The honest trade-off with stamping: fin height is constrained by sheet thickness and formability, so thermal resistance is higher than extruded or forged alternatives at the same footprint. If your junction temperature budget is tight and the dissipation load is above 30–40W sustained, it's worth a conversation about which process actually fits.

Taiwan.5Process types30+Years experience2 daysQuote turnaroundBending Fin Cold Forged Heat Sink Skived Fin Heat Sink Zipper Fin Die Cast Aluminum Parts Aluminum & Copper OEM Custom Profile ISO 9001 CertifiedCustom Heatsink DesignStandard profiles cover 80% of applications. This is for the other 20%.Extrusion handles most jobs. But there's a category of thermal application where the fin aspect ratio is too high for extrusion, the geometry is too complex for stamping, or the dissipation load demands something purpose-built. That's what custom heatsink design is for.HTC's custom heatsink design capability spans five distinct processes — each with a different performance envelope and cost structure. Knowing which one fits your application is part of the engineering conversation, not something to figure out after tooling is cut.Bending Fin Cold Forged Skived Fin Zipper Fin Die Cast Aluminum"Cold forging pushes AL1070 to ~220 W/m·K. Skiving creates fin aspect ratios that extrusion can't reach. Die casting handles 3D geometry in a single shot."Cold forged heat sinks use AL1070 — a purer aluminum alloy with conductivity around 220 W/m·K, versus 160–180 for extruded AA6063. The forging process densifies the grain structure and allows very high, very thin fins. It's the right call when junction temperature budget is tight and mounting footprint is constrained.Skived fin heat sinks are cut directly from a solid block — fins and base are one continuous piece of metal. No bonding interface, no thermal contact resistance between fins and base. For high-frequency power cycling applications, that structural integrity matters more than the conductivity number alone.Die cast aluminum parts handle what neither extrusion nor forging can: true 3D complexity in a single tool. If your thermal component doubles as a structural housing, or has features on multiple faces, die casting is usually the process that makes it possible at production volume.Send us a drawing, a thermal simulation output, or just a component description.

Heatsink plus fan plus hardware, shipped as one assembly.FullAssembly in-houseAL & CuMaterial optionsOEMCustom availableCPU Cooler Heat Sink Fan Cooled Heat Sink Heat Sink with Cooling Fan Copper CPU Heat Sink Fan Thermal Camera Module Fan Mounting & Wiring OEM Assembly ISO 9001 CertifiedThermal ModuleA heatsink alone isn't always the answer. Sometimes the whole thermal system needs to ship as one part.There's a difference between buying a heatsink and buying a thermal module. A heatsink is a component. A thermal module is an assembly — heatsink, fan, mounting hardware, and wiring — integrated, tested, and ready to drop into your system without further sub-assembly on your line.HTC's thermal module offering covers the full range. CPU cooler heat sinks for computing and server applications, where copper base plates or copper heat pipes are often specified because the Tj budget for high-performance processors is unforgiving. Fan cooled heat sinks where the fin design and fan static pressure curve are matched together, not selected independently. And thermal camera modules for imaging and sensing applications that need both thermal dissipation and optical positioning built into the same mechanical package."Matching the fan's static pressure curve to the heatsink's fin resistance — that's engineering. Buying them separately and hoping they work is not."The case for sourcing a complete thermal module from a single supplier isn't just logistics. When HTC assembles the fan to the heatsink in-house, the interface is verified — fan seating, vibration isolation, wiring routing. If there's a thermal performance issue during qualification, there's one contact point, not two suppliers pointing at each other.Copper CPU heat sink fans are available for applications where aluminum conductivity isn't sufficient — particularly high-TDP processors in compact chassis where spreading resistance at the base matters as much as fin surface area. Thermal resistance measurements are available on request for qualified production samples.Describe your thermal load, available airflow, and mechanical envelope.

The first is secondary operations on extruded or forged heatsinks — drilling mounting holes, tapping threads, pocket machining for component recesses, custom length cutting. Fast, repeatable, dimensionally tight.The second is standalone precision CNC machined components — parts where the machining itself is the primary manufacturing step, not a secondary process. Structural brackets, heat spreader plates, custom housings, and aerospace-grade components where the drawing tolerances are in the ±0.01–0.05 mm range and every feature is dimensionally verified before shipment."First-article inspection documentation on every new program. Production sampling on every run. Not optional — standard."HTC's CNC machining for aerospace parts is a specific capability, not a marketing claim. Aerospace applications demand material traceability, process documentation, and dimensional reporting that general commercial machining doesn't require. The quality infrastructure — incoming material inspection, in-process measurement, first-article reports — is in place for customers whose programs require it.Both milling and lathing are handled in-house. Milling covers prismatic parts, pockets, contours, and multi-face features. Lathing handles rotational symmetry — turned shafts, threaded inserts, cylindrical housings. For components that require both operations, they're sequenced on the same production floor without sub-contracting hand-offs.Materials include aluminum alloys (6061, 6063, 7075), copper, and steel. Surface treatment options — anodizing, nickel plating, chromate conversion — are available in-house for machined aluminum components. Send a 2D drawing or 3D STEP file.
