Stamped
Heat Sink

When unit cost is the constraint. 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.

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. HTC's engineering team will tell you directly — including when stamping isn't the right answer.
