IATF 16949 and ISO 9001 certified, with ISO 13485 compatible controls for medical programs. Every lot is traceable to its powder batch, its mould and its sinter charge. You are welcome to audit us in person or remotely.
Certificates and audit reports are released during supplier qualification. Ask and you get the PDF the same day.
| Standard | Scope | What it means for your program |
|---|---|---|
| IATF 16949 | Automotive QMS | APQP, PPAP, PFMEA, MSA and SPC are working practice, not paperwork added for one customer. Applies to every line, not only automotive jobs. |
| ISO 9001 | General QMS | Documented procedures, internal audit programme, management review, corrective and preventive action with closure evidence. |
| ISO 13485 compatible | Medical device parts | Segregated medical production flow, enhanced traceability, cleanliness control and validated cleaning for instrument components. |
| RoHS / REACH | Materials & coatings | All feedstock, plating chemistry and coatings screened. Declarations issued per part number on request. |
| ISO 2768 / ISO 1101 | Dimensional standards | Default general tolerances and GD&T interpretation when your drawing does not specify otherwise. |
| ISO 2859-1 | Sampling inspection | Outgoing AQL sampling plans: 0.65 critical, 1.0 major, 2.5 minor unless your control plan overrides. |
Dimensional data alone does not prove a sintered part is right. Density, hardness, microstructure and mechanical properties all get measured.

Full GD&T verification against your drawing datums. FAI reports are issued in your format or ours, with actual values not just pass/fail.

HRC, HRB and HV testing on core and case. Carburized parts are sectioned to confirm case depth against the specification.

Sintered density is the single best indicator of a healthy sinter cycle. Measured per lot and trended over time.

Tensile strength, yield and elongation on sintered test bars per ISO 6892, run alongside the production lot.

Sectioning, mounting, polishing and etching to check porosity distribution, grain structure, decarburisation and case depth.

Ra, Rz and Rmax per ISO 4287 on functional and sealing faces, before and after finishing operations.
Standard package is included at no extra cost. Extended packages are quoted per program.

Powder lot verification against certificate, moisture and flow checks, feedstock batch record opened and linked to the lot.
Green part weight and dimension checks per shift, sinter furnace profile recorded per charge, density sampled per lot.
Dimensional re-check after machining and heat treatment, hardness and coating thickness verified, visual criteria applied.
AQL sampling per ISO 2859-1, documentation package assembled, packing verified, shipment released by QA.
We host customer and third-party audits throughout the year. On-site audits can be scheduled with two weeks' notice; remote audits run over video with live floor walkthrough and document sharing.
What auditors typically review: process flow and control plan alignment, calibration records, non-conforming material handling, training records, and traceability from a finished carton back to a powder lot. We can run that trace live for any part number you pick.
No supplier has a zero-defect history over 31 years. What separates a good supplier is what happens in the 48 hours after a complaint lands.
| Acknowledgement | Within 24 hours of receiving the complaint |
|---|---|
| Containment | Within 48 hours — stock sorted, shipments held |
| Root cause (8D D1–D4) | Within 5 working days |
| Permanent action (D5–D7) | Within 15 working days |
| Effectiveness verification | 3 consecutive lots monitored and reported |
IATF 16949 and ISO 9001, with ISO 13485 compatible controls for medical work. All materials and coatings meet RoHS and REACH. Certificates are released during supplier qualification.
Yes. Levels 1–3 are standard, including control plan, PFMEA, process flow, dimensional and material results, MSA and the part submission warrant. Level 4–5 to your defined content.
ISO 2859-1 at AQL 0.65 for critical and 1.0 for major characteristics. Tighter sampling or 100% inspection where the control plan calls for it.
Each lot links to powder batch, feedstock batch, mould number, sinter charge record and inspection results. Records retained a minimum of three years.
Yes — on-site with two weeks' notice, or remotely over video with live floor walkthrough. We have hosted SGS, TÜV, BV and Intertek audits.
Cpk ≥ 1.33 on critical characteristics for series production, with SPC charts available on request. Capability studies are run during PPAP and re-verified after any process change.
Practical answers for OEM sourcing and engineering teams.
Yes. SINTS holds IATF 16949 and ISO 9001, and runs ISO 13485-compatible controls for medical components.
CMM, Rockwell/Vickers hardness testing, Archimedes density, universal tensile testing, metallographic microscopy and surface-roughness measurement.
COC, material certificate, dimensional report, FAI, PPAP levels 1-3, SPC data, mechanical and metallographic reports, and RoHS/REACH declarations.
Yes. On-site and live video factory audits are both supported.
