A rubber-part PPAP submission should connect the customer's requirements with the material, production process and sample evidence being submitted. Agree the applicable requirements, submission scope, format and approval responsibility before preparing the package. A completed set of files and customer approval are separate milestones.
AIAG describes PPAP as a part-qualification process addressing the supplier's understanding of customer requirements and the process's potential to produce conforming product on a production basis. For rubber parts, keep that purpose visible as drawings, compound records and test reports are assembled.
Begin with the controlled requirements
Identify the part number, drawing revision, material specification and customer-specific requirements. Mark critical dimensions and properties, and record the methods and acceptance limits that apply. Resolve unclear callouts before they are carried into the sample and report package.
For a formal PPAP request, confirm the required submission level and customer instructions. Do not assume every order requires the same level. For an industrial project using a different approval process, agree the necessary evidence without labelling that process a formal PPAP by default.
Connect each record to the part being approved
| Evidence group | Rubber-specific connection to preserve |
|---|---|
| Drawing and specification | Revision, geometry, material callout and customer additions |
| Material identification | Proposed compound code, preparation and the samples represented by each report |
| Process flow and risk/control records | Relevant mixing, molding, finishing, inspection and packing operations |
| Measurement and test results | Methods, sample identification, conditions, limits and actual results |
| Sample parts | Tool or cavity, material lot and production conditions required by the submission |
| Approval and change records | Responsible customer representative, disposition and agreed change requirements |
This is a discussion framework, not a replacement for the customer's required checklist. Confirm which records must be submitted, retained or made available, and which sample-retention arrangements apply.
Include material behaviour as well as dimensions
Review the properties that drive the application: hardness, mechanical response, compression behaviour, contacting-media resistance or another specified requirement. Each selected test needs a defined method and acceptance basis. A polymer name alone does not identify the approved production compound.
Keep test specimens and finished-part results distinguishable. Explain which material or component each report represents and how it relates to the production sample. Do not use an unrelated historical data sheet as though it were a result from the submitted lot.
Check the traceability chain before handover
Connect material identification, work orders, relevant process records, inspection and shipment information according to the project requirements. The batch-traceability guide provides the questions needed to review those links.
Where capability data are required, identify the characteristic, measurement system, sample sequence and analysis basis. See the SPC report-reading guide; a capability number without its conditions does not complete the submission.
Record the approval decision and later changes
Identify who reviews the submission and what remains open after any sample evaluation. Retain the customer disposition with the approved part and material revisions. If changes are proposed later, use the applicable customer notification and approval requirements rather than treating the original package as permanent authorization for all substitutions.
RubberQ has IATF 16949, in-house compounding, molding, testing and ERP traceability. Discuss the documentation and sample scope required for your program. Submit the drawing and approval requirements with expected quantities, or review the quality-system information before the technical discussion.
