Stamping bracelet is a single-stroke formed SPCC steel 1.0 mm part with fins and a flat base, rated at ΔT = 60 K for solar tracker builds. Standard zinc plating is 8-12 µm, applied after forming to protect fin roots. Low fin gauge and high fin density give more surface per cubic millimetre than machined or extruded profiles, and monthly output scales from one press family.

A single stroke forms the whole stamping bracelet, so part cost stops scaling with complexity. Tooling runs , and the cycle feeds a line.
Low fin gauge is where stamping wins: fins at pitch give more surface per cubic millimetre than a machined or extruded profile of the same envelope.
One supplier now covers to fin gauges from the same press family, so a thermal redesign is a tooling change rather than a new vendor.
Pressing SPCC steel 1.0 mm keeps the stamping bracelet light, from depending on envelope, without sacrificing fin density, which matters where airflow path length is already fixed by the enclosure.
The zinc plating 8-12 µm 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 SPCC steel 1.0 mm, supplied with zinc plating 8-12 µm. For applications where solar tracker 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 , 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.

Flatness is checked on a against a limit, and fin pitch is verified optically at . Reports go out with each lot.
Sampling is AQL 0.65 for critical dimensions and 1.5 for general, with on every first article. Deviations beyond trigger a full-lot sort.

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.

In solar tracker, the rating determines how much airflow the enclosure still needs. At solar tracker junction temperatures, fins at pitch keep the delta-T inside the sensor budget.
In solar tracker, the base usually doubles as the mounting interface. with flat gives a stable surface for the solar tracker thermal pad.
Designers working on solar tracker ask for flatness before they ask for thermal data, because solar tracker assembly is automated and a non-flat base stops the line.
For solar tracker prototypes, covers drawing review and first article. Production lots move to 18 working days once the capability is signed off.

measured on . This is the number that matters for solar tracker, because the thermal pad needs even contact. If your assembly needs better, say so and we can add a skim operation.
Standard packing is . We quote . Export cartons are labelled with lot, quantity and inspection status, and full documentation including the inspection report travels with the goods.
We supply a 2D drawing with the CMM report, and 3D STEP on request. Both show flatness callouts and tooling split lines, which matters if you are checking in your own assembly.
The plant is ISO9001 certified, and parts ship with RoHS and REACH declarations on request. Third-party SGS inspection can be arranged before the container is sealed, which is what most solar tracker buyers specify.

The key is avoiding a second metal at the wet contact area. We recommend zinc plating 8-12 µm and, where the part touches an aluminium chassis, an isolating washer. Tell us the mating material and we will specify the coating accordingly.

Source-direct from Dongguan: coil stock, forming, surface treatment and inspection happen in one building, so flatness is verified before the part is packed.
Production runs on cycles with in-line vision on . That is what keeps a commitment credible in peak season.
Quality staff sit beside the press, not in a separate room. Deviations on or stop the run at the tool rather than at final inspection.

Yes. Tolerance classes you can specify are covered in the article section Tolerance Classes You Can Specify. Because a single stroke forms the whole part, part cost stops scaling with complexity. Provide your drawing with required tolerance class, and inspection before every shipment verifies the specified dimensions.
Tooling runs and the cycle feeds a line, supporting monthly output for solar tracker builds. Lead time depends on tooling and order schedule. One supplier now covers fin gauges from the same press family, so a thermal redesign is a tooling change rather than a new vendor.

Yes, we can adjust fin pitch, fin height, and base flat dimensions. Low fin gauge and high fin density are achievable from the same press family. A thermal redesign is a tooling change rather than a new vendor. Provide your envelope and ΔT requirement for a quote.
Tooling lead time is 4-6 weeks. Production lead time is 2-4 weeks after tooling approval. For repeat orders, lead time is 2-4 weeks. Monthly output scales from one press family, so larger volumes can be scheduled without new tooling.
Yes, zinc plating 8-12 µm applied after forming protects fin roots and provides standard corrosion resistance for outdoor solar tracker builds. For harsher environments, additional coating or thicker plating may be specified. We apply plating after forming to ensure full coverage.
MOQ is 5,000 pcs per variant. This covers setup and tooling amortization. For larger monthly output, we can scale from one press family. Contact us for volumes above 500,000 pcs/month.
We inspect incoming SPCC steel 1.0 mm, monitor fin pitch and base flatness during stamping, measure zinc thickness 8-12 µm after plating, and verify ΔT = 60 K via thermal test or simulation. Records are kept for each stage. Final inspection ensures fins are undamaged.
SPCC steel 1.0 mm is used because it balances formability, strength, and cost. It allows low fin gauge and high fin density, giving more surface per cubic millimetre than machined or extruded profiles. It is light and suitable for solar tracker builds rated at ΔT = 60 K.
