A compression spring assortment kit is stamped in one stroke so every fin pitch holds within tolerance across a run, with flatness held directly from the tool and ΔT = 60 K performance applied as standard. The one-piece base-and-fin geometry eliminates brazed joints and adhesive layers, cutting the thermal path. Tooling runs repeatably and the cycle feeds a line, so part cost stops scaling with complexity.

Stamping gives a repeatable fin profile that extrusion cannot hold: the die forms every fin in one stroke, so pitch stays within across a run.
Because the base and fins are pressed as one piece, there is no brazed joint to fail. flatness on the mounting face is held directly from the tool, which keeps thermal interface contact uniform.

A single stroke forms the whole compression spring assortment kit, so part cost stops scaling with complexity. Tooling runs , and the cycle feeds a line.
The one-piece geometry removes the adhesive layer found in two-part coolers, cutting the thermal path. Nothing sits between and the airflow except the stamped surface itself.

The 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 , supplied with . For applications where vibration isolator 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 ±0.5 mm, with critical features such as held separately. Formed geometry inherits tooling repeatability of , and hole position is held to . Tighter classes need an extra press operation, so it is worth deciding before tooling rather than after.

Each batch carries a CMM report from . We record flatness, pitch, base thickness and hole position, and flag anything outside ±0.5 mm before it leaves the line.

Lot traceability runs from coil to carton: heat number, press stroke range and inspection record stay attached, so a field issue can be tied back to a specific run.
Flatness is measured on granite rather than on cast iron, because at reads differently on a plate that has not been lapped. Records keep both readings.
Final containment is . Every carton is labelled with lot, quantity and inspection status, and the record is kept for 10 years against the ISO9001 file.
For vibration isolator builds, the mounting face matters as much as the thermal rating: it decides whether thermal interface material spreads evenly or pools at one end.

vibration isolator customers typically specify for corrosion reasons and then hold the drawing to ±0.5 mm. The line absorbs the volume without a second source.
Where a compression spring assortment kit runs at vibration isolator volumes, part-to-part consistency decides field returns. on a run keeps the thermal curve inside one band.

MOQ is 500 pcs for a prototype run and 5000 pcs for production. Below the prototype quantity the tooling amortisation dominates the unit cost, so we quote the sample route instead: .
Yes. Send a drawing or a sample and we return a DFM note within 3 working days. Most vibration isolator customisations change , or the hole pattern, and all three are tooling changes on the existing press rather than a new machine.
Prototype is 10 working days from drawing approval; production is 20 working days after the first article is signed off. Tooling for a new part takes . We quote , and sea freight to Europe runs about 25 to 30 days after booking.
General dimensions run to ±0.5 mm; critical ones such as are held separately. Formed features inherit tooling repeatability of . If your drawing needs tighter, tell us before tooling so we can plan the extra press operation.
measured on . This is the number that matters for vibration isolator, because the thermal pad needs even contact. If your assembly needs better, say so and we can add a skim operation.
Source-direct from Dongguan: coil stock, forming, surface treatment and inspection happen in one building, so flatness is verified before the part is packed.
Our vibration isolator experience runs back to the first tooling programme in 2015. That history is why the standard and ±0.5 mm are conservative rather than optimistic.
Production runs on cycles with in-line vision on . That is what keeps a commitment credible in peak season.

A compression spring assortment kit is a stamped one-piece base-and-fin assembly. Every fin pitch holds within tolerance across a run, flatness is held directly from the tool, and ΔT = 60 K performance is applied as standard. The one-piece geometry eliminates brazed joints and adhesive layers, cutting the thermal path.
Stamping forms every fin in one stroke, so pitch stays within tolerance across a run. Extrusion cannot hold that repeatable fin profile. Because the die forms all fins simultaneously, the compression spring assortment kit maintains consistent pitch without secondary operations, and flatness on the mounting face is held directly from the tool.
A one-piece base-and-fin geometry has no brazed joint to fail. It also removes the adhesive layer found in two-part coolers, cutting the thermal path. The compression spring assortment kit is pressed as one piece, so thermal interface contact stays uniform and ΔT = 60 K performance is applied as standard.
