A380 fills a die that carries fin fields on all four outer walls, with the front panel openings formed by die blocks. The four walls are fed from a runner along the base, so the fins fill upward and vent at the top edge. After casting the base and the panel face are fly-cut, the connector holes are drilled, and the part is coated black with the base face masked so it still sits flat on its mounting. It is the tallest of the vertical boxes in the die casting heat sink range. At what annual volume the die pays for itself is worked out in the die cast cost breakeven guide.
Every exposed face cools.
Full height, no break in the run.
Warm air leaves the top of each channel.
Four connector cutouts, cast.
No separate lid-mounted sink.

Note: values above are KingKa build options and verified capability; final geometry, holes and finish are confirmed against your drawing.
Four fin fields on one casting compete for metal. If one wall fills before the others, the last field shorts and the part looks fine until it is measured, so the runner is balanced across the base rather than fed from one corner.
Design & CFD. 3D layout with CFD review sizes the fin field, pipe route and base thickness to the load and airflow.
Base machining. Plate, pockets and pipe channels are milled on 50+ CNC centers to +/-0.005 mm.
Fin and pipe joining. Fins skived, stacked or extruded; pipes pressed and soldered; the stack joined to the base by the process the design calls for.
Face fly-cutting. Contact face machined flat after joining so the part sits true on the device.
Final inspection. Hexagon CMM (+/-0.001 mm) and 2.5D projector check critical features; 4-stage IQC / IPQC / FQC.
Fin pitch and height - measured against the drawing before packing.
Base flatness - fly-cut face checked on the contact side.
CMM report - critical dimensions to +/-0.001 mm.
Joint inspection - solder or weld fillet checked along the stack feet.
Visual and batch audit - IQC / IPQC / FQC on every run.
All-round finned enclosures are used where the box stands free in still air:
Rack-side amplifiers
Power converters
Outdoor radio units
Industrial drives
Charging equipment
Send the box envelope, the internal board stack, the connector list and the mounting orientation. KingKa checks whether the fins should run vertically for buoyancy or horizontally for a fan, then sets the wall thickness so the four fields fill evenly from one runner. A flatter body that keeps the same cast ears is the flat housing with cast ears.
KingKa is a direct manufacturer with 16+ years in thermal production, 50+ CNC centers, in-house skiving, FSW and vacuum brazing, certified to ISO 9001:2015 and IATF 16949:2016.
Tell us the mounting orientation before the fins are drawn. Vertical channels and horizontal channels are not interchangeable, and re-cutting the die after the fact costs more than the tool did.
One supplier for the whole assembly. Base, fins, pipes and hardware under one quality system.
CFD before tooling. Design review catches a bad layout before metal is cut.
Prototype to volume. Samples in 7-15 days, production scheduled to forecast.
