What we make for France buyers
Aluminium heat sinks are made to your drawing, not to a catalogue. Typical processes are extrusion, machining, skiving, bonding and anodising. The scope starts with a DFM review so the drawing, the process and the inspection method agree before tooling or a first batch.
Common applications include inverters, EV chargers, data centres and LED lighting. A programme can start with a prototype or a small engineering batch and move to repeat production without changing the drawing basis.
Why source from India for France
India offers a deep base for heat sinks, English-speaking engineering support and a cost structure that can make a landed-cost comparison worthwhile. For France, the route usually runs through Le Havre and Marseille, with typically 18 to 30 days by sea.
The commercial case is not the piece price alone. Metal, conversion, tooling, finish, packing and freight belong in the same model. We quote the material basis and the conversion separately so you can see what moves when the metal price changes.
Materials and finishes
Typical materials are 6063 and 6061 aluminium, with copper for high-density duties. The grade and temper must match the process and the duty. A material substitution that looks equivalent on paper can change springback, conductivity, tool wear or the minimum bend radius.
Finishes include clear or black anodising and chromate conversion coating. State the standard, the thickness and any masked areas. A finish note without a thickness leaves the supplier to choose, which is where plating arguments usually start.
Quality evidence and compliance
Inspection covers profile, flatness, fin geometry and thermal resistance. The first article includes the drawing revision, material certificate, measured characteristics and any functional test. Production batches follow the agreed inspection plan.
For France, the programme can include CE marking and the applicable EU directives. Declarations and customs information can cover EU RoHS, REACH and CBAM data where relevant. The exact requirement depends on the part, the assembly and the importer, so confirm it at RFQ stage.
Shipping and Incoterms to France
We ship through Le Havre and Marseille, by sea or air depending on the batch and the date. typically 18 to 30 days by sea. The Incoterm can be FOB, CIF, DAP or DDP, but the right choice depends on who controls the freight and how the customs entry is handled.
Ask for the freight basis, the transit estimate and the documents before comparing prices. Do not treat a DDP price as automatically cheaper. It may include freight and duty, or it may simply hide them.
What to send for a useful quote
Send the current drawing, native CAD if available, material grade, finish, annual volume, release size, destination and required quality documents. Add the application and the mating part if the fit matters.
A complete RFQ removes the assumptions that make two quotes look different. If the design is still moving, say which features are fixed so the supplier can price the range and flag the cost drivers.
| Requirement | What to send | Why it matters |
|---|---|---|
| Material | 6063 and 6061 aluminium, with copper for high-density duties | Conductivity, formability and tool life |
| Finish | clear or black anodising and chromate conversion coating | Corrosion, contact resistance and lead time |
| Inspection | profile, flatness, fin geometry and thermal resistance | First article and production release |
| Delivery | FOB, CIF, DAP or DDP to France | Freight, duty and customs responsibility |
Questions buyers ask
Can Qumek supply heat sinks to France?
Yes. We manufacture through partners in India and ship to France through Le Havre and Marseille. The route and Incoterm are agreed at quotation.
What is the lead time for heat sinks?
It depends on tooling, material, finish and batch size. A first article is usually the long pole. The quote should state the tooling, sample and production lead times separately.
Which Incoterm should we use for France?
That depends on who controls freight and customs. FOB, CIF, DAP or DDP are common. Ask for the freight basis and the documents before comparing a DDP price with an FOB price.
What quality documents are included?
Typically the drawing revision, material certificate, first article report and inspection record. Additional requirements such as PPAP or a declaration can be added at RFQ stage.
