Quality you can ask for documents on
Anyone can say the parts are good. Ask for the paperwork and the argument ends. Every batch we ship leaves with a material test report, a RoHS report and dimensional records — so your own inspection has something to check against.
Where defects are stopped
Four checkpoints, in order
Most quality problems in stamped brass parts come from two places: the wrong alloy going in, or the die drifting over a long run. The checkpoints are arranged to catch both.
Incoming material
Brass strip is checked against the grade specified on the drawing — H62, H65 or phosphor bronze — with the mill’s material certificate kept on file and the strip batch recorded. If the material is not what the drawing calls for, it does not go on the press. This is the single cheapest place to prevent a quality failure, and the single most common thing a low-cost supplier skips.
First article before the run
Before mass production, the first pieces off the die are measured against the drawing and approved. The approved first article becomes the reference sample for the rest of the order — so “the same as last time” has a physical definition instead of a memory.
In-process and final inspection
Dimensions are checked during the run — which is where you catch the die wearing before the whole batch is affected — and again at the end:
- Dimensional check with calipers, micrometers and gauges on the agreed critical features
- Visual check for burrs, bent edges, incomplete forming and die marks
- Plating check — coverage, colour and adhesion — where the part is plated
- Quantity and packing check before dispatch
Documents and traceability
Each shipment leaves with the material test report, the RoHS report, the dimensional record and a batch reference that lets us trace the goods back to the strip they were made from. Packed goods are photographed before dispatch — so you know what left us, not just what arrived.
Paperwork
What ships with your goods
| Document | What it covers |
|---|---|
| Material test report | Alloy identity and composition of the brass actually used in the batch |
| RoHS report | Restricted substance compliance for the part as supplied |
| Dimensional record | Measured values on the critical dimensions agreed at quotation |
| First-article report | The approved reference sample for a new or changed part |
| Packing list | Quantity, packaging, net and gross weight per carton |
Tell us your market and the file you are building — sometimes a customer needs a specific format, a translated label or a particular declaration. Ask at the enquiry stage and it is straightforward; ask after the goods are on the water and it is not.
Ordering
Additional testing
Some applications need tests beyond the standard documentation — salt spray for corrosion resistance, conductivity, hardness, plating thickness, or a full dimensional layout on a new part.
Tell us at the quotation stage what you need tested and we will arrange it with an external laboratory and send you the report. We would rather you specify it upfront than discover a gap when your customer asks for the file.
If you need third-party inspection before shipment — your own QC, or an agency you nominate — that can be arranged on site as well. Say so when you place the order so we can time production around it.
Boundaries
What stays with you
Being precise about this saves both sides a difficult conversation later.
- Finished-product certification — CE, UKCA, UL, SNI, TIS, SIRIM, SASO, G-Mark — is issued to the finished appliance, and belongs to whoever assembles and sells it. We supply the component documents your file needs.
- Your incoming inspection — our dimensional record is there to be checked, not replaced. If your incoming inspection finds a deviation, send us the measurement and the batch reference and we will investigate against our own record.
- Application decisions — we will recommend phosphor bronze over brass where a contact has to spring, and we will say when a tolerance is tighter than the part needs. The final decision on the design is yours.
Want to see it before you commit? Ask for a sample material test report and a dimensional record from a recent batch of a comparable part. You will see exactly what format you would receive with your own order.
