This is Collection 02 for extruded aluminum heat sinks. Every part in this line is made to your drawing. We do not sell off-the-shelf blanks. You send the DWG or STEP file. We machine, deburr, and verify before shipment.
Tolerance: ±0.05 mm on machined features
Lead time: 7–12 days for prototypes, 15–20 days for production
No MOQ: order 1 piece or 10,000 pieces
Surface finish: black anodize, clear anodize, or bare
We are a precision manufacturing factory in Dongguan, China. 20 years of experience. CNC machining, metal stamping, springs, and heat sinks under one roof.
±0.05 mm on machined surfaces, ±0.1 mm on extrusion cross-section
Surface finish
Black anodize (MIL-A-8625 Type II), clear anodize, powder coat, or bare
Flatness
0.1 mm over 100 mm length
Thermal performance
Verified by calculation, not guesswork. We provide thermal resistance data on request.
Batch size
1 to 50,000+ pieces. No MOQ.
Inspection
100% critical dimension check on every batch. Full report included.
Lead time
Prototype: 7–12 days. Production: 15–20 days. Air freight available.
All extrusions are aged to T5 or T6 condition. We control the process from billet to box. No third-party subcontracting for core steps.
Three Reasons Buyers Send Us Their Drawings
1. Batch-traceable quality.
Each batch gets a unique lot number. Material certificates, machining records, and inspection results are tied to that number. If a problem appears in the field, we trace it back to the exact extrusion run and machining shift. You get full visibility.
2. Inspection report per batch.
We do not just check the first piece. Every batch gets a final inspection report with measured values for critical dimensions, surface finish, and flatness. The report is sent with the shipment. You can file it for ISO or customer audits.
3. One factory for CNC + stamping + springs + heatsinks.
Your assembly may need a stamped clip, a compression spring, and a machined heatsink. We make all three in-house. No separate suppliers. No mismatched tolerances. No shipping delays between vendors. You send one drawing package, we handle the rest.
Where These Parts Are Used
Custom heat sinks from this collection go into real products that run hot and need to survive.
Power electronics: IGBT modules, rectifiers, motor drives. Extruded profiles with high fin density for natural convection.
LED lighting: High-bay fixtures, street lights, horticultural lamps. Black anodized for emissivity.
Telecom equipment: Base stations, RF amplifiers, edge routers. Forced-air cooled with precision-machined mounting holes.
Automotive: EV battery coolers, DC-DC converters, onboard chargers. 6061-T6 for vibration resistance.
Medical devices: Laser systems, MRI power supplies. Clean surfaces, no burrs, biocompatible anodize options.
If your part needs to move heat from a junction to the air, this is the collection.
Questions Buyers Ask Before Ordering
Q: What is the MOQ?
A: No MOQ. We make one prototype for $50–$200 depending on size. Production runs start at any quantity. You pay for the extrusion die once, then per-piece pricing drops with volume.
Q: What tolerances can you hold?
A: Machined features hold ±0.05 mm. Extrusion cross-sections hold ±0.1 mm. Flatness is 0.1 mm over 100 mm. If you need tighter, we can grind or lap after machining. Tell us the critical dimensions on your drawing.
Q: How fast can I get parts?
A: Prototypes ship in 7–12 days after drawing approval. Production orders ship in 15–20 days. We use DHL, FedEx, or UPS for air freight. Sea freight is available for large batches.
Q: Do you provide material certificates?
A: Yes. Every batch includes a mill certificate for the aluminum alloy and temper. We also provide RoHS and REACH compliance documents on request.
