Custom Heat Sink/Thermal Components: manufacturing notes
Every part we ship has to perform in service, not just pass inspection. Below is how this custom heat sink/thermal components is specified and manufactured at WERIX, and which details in the drawing drive cost, lead time and yield.
Why this part is made in copper and brass
Custom Heat Sink/Thermal Components is specified in AL6063-T5 extrusion / AL1050 stamped fins / CU110 copper. Copper and brass are specified when conductivity, shielding performance or a decorative finish is the driver rather than structural strength. Both are soft and ductile, so forming is easy but the parts need careful support during handling and finishing; brass is often left as brushed or plated metal rather than painted.
How the part is formed
The production route for this part is extrusion, stamping, fin stacking, CNC machining. Stamping moves the cost from the labour line to a hardened die, which pays off from a few thousand pieces upward: cycle time stops being a labour cost and becomes machine time, and every subsequent part inherits the die’s tolerances instead of the operator’s. Below that volume the same geometry is normally lasered and formed.
What ±0.1mm actually requires on the shop floor
The drawing calls for ±0.1mm. On a part like this that is a process decision, not an inspection decision: it fixes which machine holds the critical features, how the part is fixtured for each operation, and whether a formed feature can be checked after coating or has to be measured before it. We confirm the first article against the drawing and record the values, so the tolerance is demonstrated rather than assumed. If a dimension in your drawing is tighter than this part needs, it is usually worth relaxing it — over-toleranced features are one of the quietest cost drivers in a sheet metal quote.
Finishing: anodising
anodizing Type II or nickel plating. Anodising converts the aluminium surface into a hard oxide layer instead of adding a film, so it does not chip and flake the way a coating can. It is the reason aluminium parts often ship anodised rather than painted, and the layer thickness is chosen for the service — decorative, wear-resistant or hard-anodised for moving surfaces.
Frequently asked questions
- What is the minimum order quantity for custom heat sink/thermal components?
- The order range for this part is from 100 to 100000+. Below the low end of that range the tooling and setup are spread over too few pieces to be economic, so if you are prototyping we would normally build the first units from the same process route and quote the production quantity separately.
- Can the material be changed to reduce cost or weight?
- Yes, and it is worth asking before the design is frozen. The current specification for this part is AL6063-T5 extrusion / AL1050 stamped fins / CU110 copper; depending on the service environment, a different grade or a lighter gauge with formed stiffening can meet the same requirement. What we would not do is change the material without re-checking the bend radii, the welding process and the coating system, because all three move with the substrate.
- What finishing options are available for this part?
- The current finish specification is anodizing Type II or nickel plating. Powder coating, anodising, zinc or nickel plating, brushing and blasting are all available in-house, so the finish can be changed without changing supplier — and where the part will be seen, we match colour to the RAL or Pantone reference on your drawing.
- How long does production take, and what do you need from us to quote?
- Prototypes are typically 3–7 business days and production runs 7–15 days once the drawing is released and the finish is confirmed. To quote we need the drawing or CAD file (STEP, DXF, DWG, IGES or PDF), the material and finish, the quantity and the destination — and any tolerance or inspection requirement that is not already on the drawing. You get a DFM review with the quotation, not after it.
