ISO 9001:2015 quality system
Documented procedures for incoming material, process control, in-process inspection, non-conformance handling and corrective action, audited annually by an accredited certification body.
An ISO 9001:2015 certified system, CMM measurement, material traceability by lot and first article inspection on every program — with the documentation your quality department can audit.
CharMax Precision operates an ISO 9001:2015 certified quality management system at its aluminum die casting facility in Dongguan, Guangdong, China. Quality control covers spectrometer verification of incoming alloy, first article inspection before every production release, CMM dimensional measurement with printed reports, material traceability to ingot lot, and leak testing on pressure-tight parts.
Casting quality is verified rather than assumed. Every production lot is traceable to the aluminum ingot batch it was cast from and to the logged shot parameters and die temperatures of the batch that produced it. When a dimension drifts or a porosity result changes, that record shows which variable moved.
We are deliberately clear about the limits of our certification. We hold ISO 9001:2015, not IATF 16949 or ISO 13485. We supply PPAP-format documentation for automotive programs and full traceability for medical equipment components, but we do not claim certifications we do not hold.

Documented procedures for incoming material, process control, in-process inspection, non-conformance handling and corrective action, audited annually by an accredited certification body.
Coordinate measuring machines verify dimensions, position, flatness and perpendicularity against your drawing, with printed dimensional reports issued per lot.
Every casting lot is traceable to its aluminum ingot batch and supplier certificate. Spectrometer analysis confirms alloy chemistry before casting begins.
Calipers, micrometers, height gauges, bore gauges, thread gauges and custom go/no-go fixtures cover routine production checks against an agreed sampling plan.
A full FAI report covering every dimension on the drawing is produced and approved before any production release, and again after any tooling change.
Dimensional reports, material certificates, RoHS declarations, surface finish records and PPAP-format documentation packages supplied with shipments on request.
A quality claim is only as good as the equipment behind it. This is the measuring equipment in our inspection room and what each instrument verifies.
| Equipment | Measures | Typical resolution |
|---|---|---|
| Coordinate measuring machine (CMM) | Dimensions, position, flatness, perpendicularity, profile | 0.003 mm |
| Optical spectrometer | Alloy chemistry against the material certificate | Element-level composition |
| Height gauge and granite table | Height dimensions, flatness, parallelism | 0.01 mm |
| Digital calipers and micrometers | Routine production dimensions | 0.01 mm / 0.001 mm |
| Bore and pin gauges | Hole diameter and fit class verification | H7 fit verification |
| Thread gauges | Go / no-go verification on every tapped feature | Per thread class |
| Surface roughness tester | Ra on as-cast and machined surfaces | 0.01 µm |
| Leak test rig | Pressure tightness on sealed housings and enclosures | To specified test pressure |
| Salt spray chamber | Corrosion performance of applied coatings | Per ASTM B117 hours |
| Coating thickness gauge | Powder coat and conversion coating film thickness | 1 µm |
| Hardness tester | Brinell hardness verification on castings | 1 HB |
| Projector and profile comparator | Complex profile and radius verification | 0.01 mm |
X-ray inspection and metallurgical sectioning for internal porosity assessment are arranged through accredited third-party laboratories when a program requires them.
Production lots are checked with the method appropriate to the characteristic: direct measurement, alloy chemistry verification or functional leak testing.
Inspection is distributed through production rather than concentrated at the end, so a problem is caught at the operation that caused it.
| Stage | Inspection performed | Record produced |
|---|---|---|
| Incoming material | Spectrometer alloy verification against supplier certificate | Material certificate, lot record |
| Die commissioning | Full dimensional layout of T1 samples | T1 dimensional report |
| Production release | First article inspection of every drawing dimension | FAI report, customer approved |
| In-process casting | Visual, key dimensions, shot parameter log review | Process log per batch |
| Post-machining | Critical dimensions, bore sizes, thread gauging | In-process check sheet |
| Post-finishing | Coating thickness, colour and gloss against boundary sample | Finish inspection record |
| Final inspection | Sampling plan measurement on CMM, visual, packaging check | Dimensional report per shipment |
Send your document requirements with your RFQ and we will confirm at quotation which records we can supply and which need a third-party laboratory. Certificates, control plans and inspection reports are issued in English.
Request our ISO 9001 certificateYes. CharMax Precision operates an ISO 9001:2015 certified quality management system, audited annually by an accredited certification body. The certificate covers documented procedures for incoming material control, process control, in-process and final inspection, non-conformance handling, corrective action and traceability. We will send a current copy of the certificate on request.
No, and we would rather tell you plainly than let you discover it late. We hold ISO 9001:2015 only. For automotive work we supply PPAP-format documentation and operate as a Tier 2 or Tier 3 supplier, typically under a customer's own IATF-certified quality umbrella. For medical work we manufacture equipment enclosures and structural components with full lot traceability, but we are not a supplier for implantable or patient-contact critical devices.
As standard, a dimensional report for the lot and a packing list. On request we add material certificates, RoHS declarations, coating thickness and salt spray records, leak test results, first article inspection reports, process flow diagrams, control plans and capability study data. Specify what your quality system needs at the quotation stage so the records are generated during production rather than reconstructed afterwards.
Report it with photographs and measurement data and we open a corrective action within one business day. We contain the affected lot, identify root cause using the batch process log and inspection records, and issue a written corrective action report with the countermeasure and its verification. Replacement parts are expedited, and where a defect escaped our inspection we revise the inspection plan so the same escape cannot repeat.
Yes, on request for designated critical dimensions. We measure a statistically valid sample from a production run and report Cp and Cpk against your specification limits. Be aware that as-cast features have wider natural variation than machined features, so critical dimensions requiring a high capability index should be machined after casting rather than held as cast.
Porosity is controlled at three stages: melt preparation with degassing and filtration, die design with engineered overflows, vents and gate geometry validated by flow simulation, and process control with logged shot profiles and die temperatures. Where parts must be pressure tight or heavily machined in critical areas, we design vacuum assist or use A360 alloy, and verify with leak testing or X-ray inspection.
We sign your NDA before receiving files and can sign a mutual agreement if you prefer. Your tooling is dedicated to your part and is never used for another customer, your drawings are not shared outside the engineering and production team assigned to your program, and we do not display customer parts or names in marketing material without written permission.
Send your RFQ with your document requirements and we will confirm exactly which certificates, inspection reports and process records we can supply for your program.
