The LED High Bay Stamped Aluminium Heatsink uses a 3.0 mm base and 0.5 mm fins pressed from 1050A aluminium on 250 T tooling. It holds 0.10 mm over 100 mm and delivers 0.62 K/W at ΔT = 75 K with forced air at 2.0 m/s. Monthly output reaches 120,000 pcs, with fin pitch held within ±0.05 mm across the run.

A 3.0 mm base and 0.5 mm fins define this LED High Bay Stamped Aluminium Heatsink. Pressed from 1050A aluminium on 250 T tooling, it holds 0.10 mm over 100 mm and returns 0.62 K/W at ΔT = 75 K, forced air 2.0 m/s. Monthly output runs at 120,000 pcs.
Stamping gives a repeatable 0.5 mm fin profile that extrusion cannot hold: the die forms every fin in one stroke, so pitch stays within ±0.05 mm across a 120,000 pcs run.
A single 250 T stroke forms the whole LED High Bay Stamped Aluminium Heatsink, so part cost stops scaling with complexity. Tooling runs ±0.05 mm, and the 18 s cycle feeds a 120,000 pcs line.
Low fin gauge is where stamping wins: 0.5 mm fins at 3.0 mm pitch give more surface per cubic millimetre than a machined or extruded profile of the same envelope.

Stamped construction tolerates batch variation better than extrusion: die wear shows up first as a measurable shift in fin pitch, which inspection catches at optical comparator plus CMM rather than in the field.
The sandblast + epoxy powder coating RAL 9005 finish is applied after forming, so corrosion protection does not get cut through at the fin roots the way it does on machined alternatives.
The standard material is 1050A aluminium, supplied with sandblast + epoxy powder coating RAL 9005. For applications where LED high bay lighting exposure is a concern, we recommend the passivated route; where conductivity matters more than weight, copper C110 raises thermal performance and roughly doubles unit mass.
General dimensions run to ±0.20 mm, with critical features such as ±0.05 mm on base thickness held separately. Formed geometry inherits tooling repeatability of ±0.05 mm, and hole position is held to ±0.15 mm. Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.
Each batch carries a CMM report from optical comparator plus CMM. We record flatness, pitch, base thickness and hole position, and flag anything outside ±0.20 mm before it leaves the line.
Incoming 1050A aluminium is checked for thickness and hardness before it enters the press. After forming, optical comparator plus CMM confirms 0.10 mm over 100 mm and 3.0 mm against the drawing.
Flatness is measured on granite rather than on cast iron, because 0.10 mm over 100 mm at 200 x 100 x 50 mm reads differently on a plate that has not been lapped. Records keep both readings.
Final containment is Anti-static bag + wooden crate over 50 kg. Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.

In LED high bay lighting, the 0.62 K/W rating determines how much airflow the enclosure still needs. At LED high bay lighting junction temperatures, 0.5 mm fins at 3.0 mm pitch keep the delta-T inside the sensor budget.
LED high bay lighting programs are the reason this geometry exists. Where the enclosure cannot grow taller, fin density is the only lever, and 3.0 mm pitch with 0.5 mm stock is the practical ceiling for aluminium.
In LED high bay lighting, the base usually doubles as the mounting interface. 3.0 mm with 0.10 mm over 100 mm flat gives a stable surface for the LED high bay lighting thermal pad.
Further technical detail: LED Heat Sink Design: Why Thermal Management Determines LED Lifespan and Performance.
Designers working on LED high bay lighting ask for flatness before they ask for thermal data, because LED high bay lighting assembly is automated and a non-flat base stops the line.

Prototype is 7 working days from drawing approval; production is 18 working days after the first article is signed off. Tooling for a new part takes 30 working days. We quote FOB Guangzhou, and sea freight to Europe runs about 25 to 30 days after booking.
Yes. Standard is sandblast + epoxy powder coating RAL 9005. Powder coating to RAL 9005 adds about 0.1 mm to the base; zinc-nickel is better for grounding. Note that any added coating sits between 1050A aluminium and the airflow, so we do not coat the fin roots.
On 1050A aluminium at normal press tonnage, expect a tooling life of roughly 300,000 strokes. At 120,000 pcs that is 6 to 12 months. We keep spare die sets on site for LED high bay lighting programs, which removes the wait if wear shows up in the flatness record.
Yes, we ship as-pressed for customers who do their own finishing. The risk is handling marks on 0.5 mm fins, so we pack those parts with interleaving sheets inside Anti-static bag + wooden crate over 50 kg.
The family covers 200 x 100 x 50 mm, with unit weights from 650 g. Because the base is pressed, new sizes are a die insert change rather than a new press line, so development is usually 2 weeks rather than 8.
The line sits in Dongguan in a single ISO9001 plant. 250 T presses cover the LED High Bay Stamped Aluminium Heatsink family, and 120,000 pcs per month is current committed output.
Tooling is built in-house, which is how ±0.05 mm is held across a 120,000 pcs programme rather than drifting part by part.
Production runs on 18 s cycles with in-line vision on 0.10 mm over 100 mm. That is what keeps a 120,000 pcs commitment credible in peak season.

Monthly output runs at 120,000 pcs. A single 250 T stroke forms the whole heatsink on an 18 s cycle, so part cost stops scaling with complexity and the line feeds 120,000 pcs per month.
The sandblast plus epoxy powder coating RAL 9005 finish is applied after forming. Because it goes on after the 250 T stroke, corrosion protection does not get cut through at the fin roots the way it does on machined alternatives.
Inspection runs before every shipment using an optical comparator plus CMM. It catches die wear as a measurable shift in fin pitch, and verifies the 0.10 mm over 100 mm tolerance and the 0.5 mm fin profile across the 120,000 pcs run.
