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. This page is about stamped aluminum heat sinks and cooling fin collections.
We do not sell off-the-shelf parts. We make your design. You send the 2D or 3D file. We build it, measure it, and ship it with proof.
At a glance: Stamping tolerance ±0.05 mm. Lead time 7–15 days for standard batches. No MOQ. Material certs included. 100% dimension check before packing.

1. Batch-traceable quality. Every heat sink gets a unique lot number. We record the material heat number, die number, and operator. If a problem appears in your field, we trace it to the exact shift and coil. No guesswork.
2. Inspection report per batch. You get a hard copy and PDF. It lists dimensions, surface finish, flatness, and material hardness. We use a CMM for critical holes and an optical comparator for fin profile. We do not skip checks. If a batch fails, you know before it ships.
3. One factory for CNC, stamping, springs, and heat sinks. Your assembly may need a stamped base, a CNC-machined mounting block, and a compression spring for a clip. We make all three under one roof. Fewer suppliers, fewer handoffs, fewer excuses. You get one invoice, one quality standard, one shipping date.
Our stamped aluminum heat sinks go into real products that run hot and run long.
If your part moves air or conducts heat, we can stamp it.

Q: What is your MOQ? A: No MOQ. We make one prototype for your test. Production pricing starts at 100 pieces. For high-volume runs, we build a dedicated progressive die to lower your unit cost.
Q: How do you guarantee tolerance and quality? A: We quote your drawing, not a guess. First article is measured and sent to you for approval. Production batches are checked at the start, middle, and end of the run. Critical dimensions go on a CMM. You receive the inspection report with the shipment.
Q: What is your lead time for custom heat sinks? A: Prototype: 7 days after drawing approval. Production: 15 days for standard batches. For urgent orders, we can split the die and run two shifts. Air freight is on you, but we pack so nothing bends.
Q: Do you provide material certificates? A: Yes. Every coil of aluminum comes with a mill certificate. We also provide RoHS and REACH declarations. If you need a specific alloy or temper, we buy it to your spec and show you the paper.
Stop guessing. Send us your heat sink drawing and get a firm quote in 12 hours.
We are a precision manufacturing factory in Dongguan, China. Custom heat sinks are our core line. Made in China does not mean low quality—it means fast, flexible, and honest. No MOQ, no hidden tooling fees, no surprise delays.
