Automotive Quality System

IATF 16949 Certified Manufacturing

Dongguan Chaorui Precision Technology Co., Ltd., the manufacturing entity behind SPI's certified machining operations, holds IATF 16949:2016 certification for the machining of metal parts. For automotive programs, SPI can support customer-defined approval, traceability, inspection, and process-control requirements according to the agreed project scope.

Certificate boundary: the certified activity stated on the current certificate is machining of metal parts, with product design excluded. Certification confirms the audited quality-management-system scope; it does not by itself constitute PPAP approval or acceptance of a specific part.

Certificate Verification

What Automotive Buyers Should Verify

An IATF 16949 logo alone does not define whether a certificate applies to a specific supplier, site, manufacturing process, or automotive program. Procurement and SQE teams should review the legal entity, production location, certified activity, exclusions, validity, and customer-specific requirements before using certification as part of supplier or project approval.

Certified Organization Dongguan Chaorui Precision Technology Co., Ltd. The legal manufacturing entity named on the certificate.
IATF Certificate 0585745 AENOR certificate reference RA02-0820/2025.
Certified Activity Machining of Metal Parts The certified scope must not be extended to unrelated processes.
Exclusion Product Design The certificate explicitly identifies product design as excluded.
Production Site Chang'an Town, Dongguan, Guangdong Buyers should confirm that the project is routed through the certified site.
Validity Through 13 October 2028 Certificate status should be rechecked during supplier approval.

Buyer verification rule: certification demonstrates an audited automotive quality-management system within the stated scope. It does not automatically approve a part, PPAP submission, capability target, inspection plan, or customer-specific requirement.

Injection molding, tooling, assembly, or other SPI capabilities must be evaluated separately and should not be presented as covered by this certificate unless the certified scope explicitly includes them.

Automotive Approval Evidence

PPAP, Traceability and Process Control

Automotive approval evidence should be defined by the customer, drawing, program stage, special characteristics, and applicable customer-specific requirements. SPI can support agreed PPAP documentation, production traceability, control records, and change-related evidence without assuming that every project requires the same submission level or document package.

Production Approval

Customer-Defined PPAP Scope

Submission level, customer forms, dimensional results, material evidence, control records, and supporting documents should be confirmed before sampling or production approval.

Production Identity

Lot, Material and Revision Traceability

Where required, production identity can be linked to the relevant material lot, drawing revision, manufacturing batch, inspection record, or other agreed traceability reference.

Controlled Production

Process and Change Control

Approved control requirements should define what is monitored and when a process, material, drawing, tooling, or manufacturing change requires review, additional validation, or renewed customer approval.

Requirement Typical Trigger Evidence to Define Important Boundary
PPAP / Production Approval Customer or program approval requirement Submission level, forms, records, samples and approval stage Do not assume Level 3 or one package for every project
Traceability Material, lot, revision or customer traceability requirement Required production and inspection identifiers Traceability alone does not prove part conformity
Process / Change Control Approved production process or engineering change Control record, impact review and required revalidation evidence Customer approval requirements depend on the specific program

Approval rule: IATF 16949 certification does not prescribe one universal PPAP submission package for every SPI automotive project. The customer and program requirements determine the evidence, approval route, and release criteria.

Special Characteristics & Capability

CTQ, SPC and Capability Requirements

Automotive programs may require defined controls for critical or special characteristics, but the measurement method, monitoring frequency, capability index, sample plan, and acceptance target should be established by the customer and project requirements. SPI can support agreed CTQ control and capability evidence without applying one universal threshold to every feature.

Characteristic Definition

CTQ / Special Characteristics

Critical features should be identified from the released drawing, specification, customer designation, or approved control plan before inspection and production monitoring are defined.

Measurement Confidence

MSA and Inspection Method

Measurement systems should be appropriate for the tolerance, feature, datum condition, and customer requirement so reported capability data is based on a controlled inspection method.

Process Evidence

SPC / Capability Study

Statistical monitoring or capability studies may be required for selected characteristics using production-representative data and the acceptance criteria defined for the program.

Requirement Define Before Study Evidence Important Boundary
CTQ / Special Characteristic Feature, tolerance, datum condition and customer designation Defined inspection and control requirement Not every drawing dimension is automatically a CTQ
SPC / Process Monitoring Characteristic, frequency, subgroup or monitoring method Production trend or control evidence Monitoring scope should follow the approved control plan
Capability Study Index, sample plan, process condition and acceptance target Cpk, Ppk or other agreed statistical evidence No universal capability threshold should be assumed

Capability rule: statistical evidence should be applied only to the characteristics and production conditions defined by the customer or approved project plan. Certification alone does not set one Cpk or Ppk target for every part.

Need the detailed logic for capability indices, CTQ studies, and how Cpk should be interpreted?

Certified Scope & Project Routing

Certified Machining and Related Automotive Manufacturing Support

SPI’s current IATF 16949 certificate applies specifically to machining of metal parts at the certified Dongguan production site. Other automotive capabilities must remain separate from this certified scope for supplier qualification.

Inside Certified Scope

Machining of Metal Parts

Automotive metal parts routed through the certified site may be managed within the stated IATF 16949 machining scope, subject to the drawing, inspection plan and customer approval route.

For programs requiring drawing-defined CTQs, inspection evidence and traceability, review our Automotive CNC Machining capabilities.

Project-specific PPAP and change-control requirements should be confirmed before release.

Related SPI Support

Molding, Tooling and Other Processes

SPI also supports injection molding, tooling, prototyping and other automotive manufacturing routes. These capabilities must be evaluated separately and should not be described as IATF-certified unless the certificate scope explicitly includes them.

Certified Machining Define the quality plan from certificate scope and customer requirements.
Automotive Injection Molding Use the dedicated route for molding requirements.
Multi-Process Programs Confirm the applicable site, process and quality documentation for each stage.

Certification boundary: do not infer that injection molding, tooling, assembly or another SPI process is IATF-certified solely because the project is automotive. The certificate applies only to the activity and site stated on the certificate.

Project Evidence

Automotive Project Evidence and Case Studies

Automotive supplier qualification should be supported by project-specific evidence rather than certification claims alone. Depending on the program, buyers may need dimensional results, material and traceability records, production-approval documents, process-validation evidence, or controlled records tied to the released drawing and agreed manufacturing route.

Evidence Type What Buyers Should Verify Typical Project Use Boundary
Dimensional / CTQ Evidence Drawing revision, inspection scope, datum logic and acceptance criteria First article, sampling, production approval or controlled inspection Measured conformity does not by itself prove process capability
Material / Traceability Records Material identity, lot or batch reference, revision and required linkage Receiving, production traceability and customer documentation Traceability alone does not prove part acceptance
Approval / Validation Evidence Required PPAP scope, customer forms, validation stage and release criteria Customer approval and repeat-production readiness Submission requirements are program-specific

Evidence boundary: automotive case studies can demonstrate how inspection, traceability, validation, and approval requirements were handled in specific projects. They do not expand the certified IATF 16949 activity beyond the scope stated on the current certificate.

Review project examples involving automotive molding, dimensional control, material evidence, traceability, and approval documentation.
