Your drawing. Our machines. A heat sink that fits the first time.
We are BQUQ, a precision manufacturing factory in Dongguan, China. We have run CNC machining, metal stamping, spring, and heat sink lines for 20 years. Every custom heat sink we ship is verified against your drawing before it leaves the floor. No guesswork. No surprises.
Tolerance: ±0.05 mm on critical fins, ±0.1 mm on overall dimensions.
Lead time: 7–12 days for CNC prototypes, 15–20 days for stamped production runs.
No MOQ. Send one drawing or ten thousand pieces. Same process control.
Material certs and full inspection report included with every batch.
Specifications
We build heat sinks the way your thermal engineer drew them. Not a generic extrusion with holes drilled in the wrong place.
7 days for CNC sample, 15 days for stamped production
All material certs are mill-issued. We keep a sample from every batch for 12 months. If you need to trace a problem, we can pull the actual metal.
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality.
Every heat sink gets a batch number. That number ties to the material cert, the machine operator, the inspection report, and the CMM data. If your customer rejects a part, we can tell you exactly which melt of aluminum it came from. That is rare for a made-in-China supplier. We do it on every order.
2. Inspection report per batch.
You do not have to trust us. We send you the numbers. Dimensional checks, flatness readings, surface finish, and thread gauge results. For critical parts, we include photos of the CMM probe points. You can verify against your drawing before we even ship.
3. One factory for CNC + stamping + springs + heat sinks.
Your power supply assembly probably needs more than just a heat sink. It needs a stamped bracket, a spring clip for the MOSFET, maybe a CNC-machined base plate. We do all of it under one roof. One purchase order. One quality system. No juggling three suppliers across time zones.
Where These Parts Are Used
Custom heat sinks from BQUQ go into equipment that runs hot and runs long.
Power supply units – AC-DC converters, server PSUs, telecom rectifiers. We machine the base to match your IGBT or MOSFET footprint exactly.
EV charging modules – High-current chargers need aluminum-copper hybrid sinks to spread heat fast. We bond the copper insert into the aluminum base with full coverage.
Industrial inverters – Variable frequency drives and servo amplifiers. Stamped fin packs with pressed-in bases for high-volume production.
LED drivers – Constant-current drivers for street lighting and horticulture. Black anodized for maximum emissivity.
Battery management systems – Liquid-cooled and air-cooled plates for energy storage racks.
Medical power supplies – Low-noise, high-reliability sinks with nickel plating for corrosion resistance.
If your part moves heat from a semiconductor to air or liquid, we can make it.
Q: What is your MOQ?
A: No MOQ. We run one prototype for $150 plus shipping. Production runs start at any quantity. We quote the same unit price for 50 pieces as for 5,000 pieces, with only a small setup fee for small batches.
Q: How do you guarantee tolerance and quality?
A: We inspect every critical dimension on a CMM. For stamped parts, we check the first article and then every 50th piece during the run. You get the inspection report with the shipment. If a part is out of spec, we remake it at our cost. No arguments.
Q: What is your lead time?
A: CNC prototype: 7 days. Stamped sample: 10 days. Production: 15–20 days depending on quantity and surface treatment. Anodizing adds 3–4 days. We ship via DHL, FedEx, or air freight from Shenzhen. Door-to-door in 3–5 days to the US or Europe.
Q: Do you provide material certificates?
A: Yes. Every batch ships with a mill certificate for the aluminum or copper. We also provide RoHS and REACH declarations on request. For medical or automotive work, we can provide full PPAP documentation.
Send Your Drawing
Stop guessing. Get a firm quote in 12 hours.
Email your 2D or 3D file to sc@bquq.com. Include the material, quantity, and surface finish if you know them. If you do not know, we will recommend based on your thermal load.
Our engineers will review the drawing for manufacturability. We will flag any tight tolerances or thin fins that will drive up cost. Then we send you a fixed quote with a lead time.
No MOQ. No hidden tooling fees. No runaround.
