What is included in the CYES factory audit package?

The package includes a company profile, factory layout, equipment list, ISO management-system certificates, cleanroom classification report, CTI material test reports, a sample first-article inspection (FAI) report, a Cpk process-capability study, a calibration summary and a PPAP checklist. Sensitive items such as exact certificate numbers and raw measurement data are released under NDA for qualified projects.

Can I audit the factory in person or remotely?

Yes. We support on-site factory visits and virtual audits (live video walkthrough). Both are available after an initial documentation review and NDA, so you can verify the equipment, cleanroom area, quality laboratory and production lines against the documents we provide.

Are the ISO certificates and test reports the originals?

We provide the original certificates and reports for review during customer qualification. Identifiable fields such as exact certificate numbers, certified legal entity, scope and validity dates are shared in full so you can verify each document directly with the issuing certification body or test laboratory.

How quickly can I receive the audit package?

The standard documentation package is typically shared within a few business days of a qualified inquiry. Client-specific records and raw measurement data require an NDA and are released on a project-by-project basis.

Factory Audit & Quality Documentation Package

You should be able to verify what we claim, not just read it. This single documentation package lets you audit our factory, equipment, certificates, test reports and process capability before you commit to a project.

What's Inside

Documents That Support Every Claim

Each document below maps to a specific manufacturing claim on this site. Together they form the evidence base an engineering buyer needs to qualify a supplier.

Document	What it verifies	Availability
Company Profile	Legal entity, founding year, factory location, business scope and ownership structure	On request
Factory Layout	Production areas — mold shop, compression, LSR, cleanroom, QC lab, packaging and warehouse	On request
Equipment List	Actual machine brands, models and quantities at the stated location	On request
ISO Certificates	ISO 9001 / 14001 / 45001 / 13485 management systems, with certified entity, scope and validity	On request
Cleanroom Report	ISO Class 7 classification of the designated medical LSR area (cert. CR-2026-0714)	On request
CTI Material Reports	FDA, LFGB, RoHS, REACH and related compliance for solid silicone and LSR	On request
FAI Sample	First-article inspection report format with measured dimensions and gauge IDs	Redacted sample
Cpk Study	Process-capability studies (LSR-MED-007, FVMQ-SEAL-010) with control charts	Under NDA
Calibration Summary	Instrument IDs, calibration dates and traceability to national metrology standards	Under NDA
PPAP Checklist	Production part approval documentation for automotive and higher-tier projects	Under NDA

Public pages show document names, scope and status. Identifiable values — exact certificate numbers, raw measurement data and proprietary process detail — are released in full during qualification, under NDA where required.

How It Works

From Request to Approved Supplier

A straightforward qualification flow — no hidden steps, no vague promises.

1. Request the Package

Tell us your product type and compliance needs. We send the standard documentation package for review.

2. Review the Evidence

Check the equipment list, certificates, test reports and capability data against your requirements.

3. Audit On-Site or Remotely

Visit the factory in Dongguan, or take a live virtual walkthrough of the production lines and QC lab.

4. Qualify & Start

Sign an NDA where needed and move into DFM, tooling and sampling for your project.

Transparency

What We Disclose, and What Stays Confidential

We publish what can be verified, and we are clear about what requires an NDA — so there are no surprises during your audit.

Published Openly

Document names, scope and status
Equipment brands and models (YIZUMI, ENGEL, BOY, MAKINO, Mitsubishi, HEXAGON)
Cleanroom classification and scope (cert. CR-2026-0714)
Process-capability results (Cpk 1.24 / Cp 1.39 / Cpk 1.32)

Released Under NDA

Exact certificate numbers and certified legal entity
Raw measurement data and control charts
Calibration certificates and instrument serial numbers
Client-specific drawings and proprietary process detail

The split above mirrors our certifications and engineering evidence pages, so the audit package lines up with what you read elsewhere on the site.
