3-axis and 4-axis mills; positional accuracy ±0.02 mm, repeatability ±0.01 mm
Stamping
Progressive dies up to 250 tons; thickness 0.5–6.0 mm; burr height < 0.05 mm
Surface finish
As-machined Ra 1.6 µm; anodized (clear, black, or custom color) up to 25 µm thickness
Tolerances
Hole positions ±0.05 mm; flatness 0.1 mm per 100 mm; mounting surfaces ground to 0.05 mm
Batch size
1 to 100,000+ pieces; no MOQ for standard alloys
Inspection
CMM reports, surface profilometer readings, and material certs per batch
We cut, mill, drill, tap, and deburr in-house. For stamped fins, we build the die and run it on our own presses. That keeps tolerances tight and lead times short.
Three reasons buyers send us their drawings
1. Batch-traceable quality.
Every heat sink gets a job number. That number follows the material from incoming billet to final inspection. If you need to know which batch a part came from, we can tell you in minutes.
2. Inspection report per batch.
You do not have to ask. Each shipment includes a dimensional report, surface finish readings, and material certificates. Our QC team measures critical features on a CMM and records them. You get the data, not promises.
3. One factory for CNC, stamping, springs, and heat sinks.
Many buyers need a bracket, a spring clip, and a heat sink for the same assembly. We make all of them under one roof. That means one purchase order, one quality standard, one shipping point. Fewer vendors, fewer headaches.
Where these parts are used
Our custom heat sinks go into equipment that runs hot and runs long.
Power electronics: IGBT modules, rectifiers, and motor drives in industrial cabinets.
Telecom infrastructure: Base station amplifiers and RF modules that dissipate 50–500 W continuously.
LED lighting: High-bay fixtures and stadium lights where thermal management determines lifespan.
Medical devices: MRI gradient coils and laser power supplies that need stable thermal performance.
Energy storage: Battery pack cooling plates and inverter heat sinks for solar and UPS systems.
If your application involves forced air, natural convection, or liquid cooling, we can machine the channels, fins, or mounting pockets to match your thermal model.
Q: What is your MOQ?
A: No MOQ. We prototype one piece and scale to 100,000. Tooling costs are quoted separately for stamped parts, but CNC-machined heat sinks have no setup minimum.
Q: How do you control tolerance and quality?
A: Every part is measured against your drawing. Critical dimensions go on a CMM. Surface finish is checked with a profilometer. We send the report with the shipment. If a dimension is out of spec, we rework or remake at no cost.
Q: What is your lead time?
A: Prototypes in 10–15 working days. Production runs in 20–25 working days, depending on quantity and finish. We can expedite for an additional fee.
Q: Do you provide material certificates?
A: Yes. Every batch includes a mill certificate for the aluminum or copper. For medical or aerospace applications, we can provide full traceability documentation.
