CNC 5axis for Electronics Thermal
Electronics-thermal hubs cover heatsinks, cold plates, spreader lids, and EMI-ish mechanical shields where conductivity, flatness, and fin or channel geometry dominate. Aluminum leads, with copper-like aspirations sometimes met by plating notes — but Batch1 children stay on listed materials. Speak thermal path and surface flatness here; leave alloy anodize deep-dives to material hubs.
Batch1 industry electronics-thermal.
Process
CNC 5-axis (simultaneous or 3+2) for multi-face and undercut geometry in this industry — applications and material mix are in the industry overlay; keep process essays off industry hub bodies.
When electronics-thermal uses this route
- Machined heatsink bases with pocketed fin precursors
- Liquid cold plates with sealed cover interfaces
- Module lids needing flatness for TIM compression
- Sensor thermal straps and spreader brackets
- Prototype thermal solutions before extrusion dies exist
Typical parts
- Heatsink bases and skived-fin blanks (machined)
- Cold-plate bodies with O-ring grooves
- IC module lids and bolster plates
- Power electronics busbar supports (mechanical)
- Thermally conductive polymer standoffs where listed
Industry DFM
- Flatness on TIM faces often matters more than tight XY hole positions
- Deep cooling channels need chip evacuation plans on 3-axis
- Anodize can add thermal resistance — confirm finish vs thermal goals on the material leaf
- Thin fin walls chatter; leave finishing stock strategy
- Do not invent CFD-certified performance numbers in hub prose
Material mix
DFM on industry hubs is application-framed (environment, sealing, weight, cleanability, thermal path). Do not paste the full process capability essay or the material-hub alloy DFM list verbatim.
Industry hub bands aggregate across child materials. Qty10 mid often sits between soft aluminum floors and higher titanium/stainless/PEEK leaves — explain the span as a material mix, not as a fake “industry surcharge.” Never invent dollar deltas beyond hub_price_ranges.json.
One-liner only: multi-axis reach. Defer collision/tilt essays to material hubs.
Public price range
Aggregated from Batch1 child leaves for this hub (5 pages). USD, rates v1.1, public ±12% on the 50×50×20 mm sample. Compare qty 10 $83.52 ($70.4–$211.27); qty 100 $367.77 ($168.57–$1196.76).
| Qty | Low | Mid | High | Status | Leaves priced | Lead days |
|---|---|---|---|---|---|---|
| 1 | $70.4 | $80 | $89.6 | priced | 5 | 7–12 (mid 10) |
| 10 | $70.4 | $83.52 | $211.27 | priced | 5 | 7–12 (mid 10) |
| 100 | $168.57 | $367.77 | $1196.76 | priced | 5 | 7–12 (mid 10) |
| 500 | $768.93 | $1531.3 | $3249.71 | mixed | 4 | 7–12 (mid 10) |
Thermal children skew aluminum but still mix polymers/steels when present; mid span is aggregate from hub_price_ranges. Industry hub bands aggregate across child materials. Qty10 mid often sits between soft aluminum floors and higher titanium/stainless/PEEK leaves — explain the span as a material mix, not as a fake “industry surcharge.” Never invent dollar deltas beyond hub_price_ranges.json. Some child leaves are mixed, so a band uses only children that published a number. Not a confirmed order price.
Process comparison
Qty 10 public mid is the median of process×material hub mids, with the span of those mids in parentheses. Tolerance labels and finish names come from the hubs-enrich pack. The machine-rate column is the rates card, not a part price.
| Process | Qty 10 price band | Tolerance | Finishes | DFM | Machine rate |
|---|---|---|---|---|---|
| CNC 3-axis (CNC 三轴) | $117.92 median ($80–$290.74) | ISO 2768-m; ±0.05 mm; ±0.025 mm; tighter needs manual | 8: Bead Blast, Powder Coat, Polish, Nickel/Zinc Plate, Anodize, Hard Anodize, Black Oxide, Passivate | On 3-axis mills, walls thinner than 0.8 mm (2V/A proxy) chatter and deflect under end-mill load — thicken or add ribs before quoting as production. | $25/h, setup $30 |
| CNC 5-axis (CNC 五轴) | $117.92 median ($80–$290.74) | ISO 2768-m; ±0.05 mm; ±0.025 mm; tighter needs manual | 8: Bead Blast, Powder Coat, Polish, Nickel/Zinc Plate, Anodize, Hard Anodize, Black Oxide, Passivate | 5-axis simultaneous moves need clearance for spindle/holder; long stick-out past thin walls under 0.8 mm risks collision and chatter — shorten tools or thicken local stock. | $55/h, setup $60 |
| CNC Turning (CNC 车削) | $117.92 median ($80–$290.74) | ISO 2768-m; ±0.05 mm; ±0.025 mm; tighter needs manual | 8: Bead Blast, Powder Coat, Polish, Nickel/Zinc Plate, Anodize, Hard Anodize, Black Oxide, Passivate | Turned bars with length/diameter above ~3–4× without a tailstock or steady rest chatter; thin tubular walls under 0.8 mm amplify ovality under chuck pressure. | $22/h, setup $20 |
| SLM / DMLS (SLM / DMLS) | $4022.82 median ($2800.17–$4177.43) | ISO 2768-m; tighter needs manual | 8: Bead Blast, Powder Coat, Polish, Nickel/Zinc Plate, Black Oxide, Passivate, Anodize, Hard Anodize | SLM thin-wall proxy under 0.8 mm (same threshold family as CNC) risks incomplete melt tracks and warp — thicken or orient flat to plate. | $45/h, support removal min $15/part |

Questions
What price does CNC 5axis for Electronics Thermal show?
Thermal children skew aluminum but still mix polymers/steels when present; mid span is aggregate from hub_price_ranges. Aggregate across 5 Batch1 materials: qty 10 mid $83.52 ($70.4–$211.27); qty 100 mid $367.77 ($168.57–$1196.76) (USD, public ±12%, rates v1.1). Open a material child for one alloy. Nothing is invented. This hub is authorized for index, follow (not a ranking claim).
Are typical Electronics Thermal parts listed?
Named production parts are not in the hubs-enrich pack. The page lists DFM one-liners and Batch1 material children for this industry. Empty means not loaded.
When can this page be indexed?
Not from this pack. SPEC §15.1 keeps process hubs index, follow, and out of the sitemap even when indexable_hint is props_ready. Indexing stays a quality-gate decision on combination pages.
