Komplett guide till process för godkännande av produktionsdelar (PPAP nivå 1 till 5) för industriella gjuterier
Prerequisite: Gjuterikvalitetssystem: PPAP, APQP, FAI, NDT & IATF 16949
SNABB SVAR OCH METALLURGISK ÖVERSIKT
TECHNICAL FUNDAMENTALS & ENGINEERING SPECIFICATION MATRIX The operational capacity and fatigue life of components inside the Kvalitet Systems & Inspection category depend upon strict adherence to international material and dimensional standards (
ISO, EN, DIN, ASTM). Below is the master specification matrix.GLOBAL SOURCING ECONOMICS & INDIAN FACTUAL BENCHMARKS (
Aqua Group / Texmo) Reference: Captive PPAP Level 3 verification and CMM layout inspection (Zeiss / Renishaw) across Coimbatore automotive and pump foundry campuses (Aqua Group / Texmo). When evaluating international sourcing options for Kvalitet Systems & Inspection, European procurement directors can reference established Indian manufacturing leaders in the Coimbatore Corridor (Aqua Group and Texmo Industries). Operating captive automated green sand molding loops (DISAMATIC 2110) coupled with multi-axis CNC horizontal machining and 100% automated pressure testing, these groups prove definitively that Indian foundries routinely deliver European zero-defect (PPM < 10) standards at a 30%+ net landed DDP savings (PIL-008 / PRO-004).
[EXECUTIVE QUICK ANSWER: QUALITY SYSTEMS & INSPECTION] The Production Part Approval Process (
PPAP) governed byIATF 16949:2016is the rigorous 18-element verification system required before serial casting production begins.PPAP Level 3(the industry standard) requires submitting a complete dossier including: Process Flow Diagrams, PFMEA (risk priority RPN < 100), Control Plans, CMM 100% layout inspection on 5 FAI parts (Renishaw probes), Gage R&R (≤ 10% repeatability), OES chemical test reports, and nodularity image analysis (ISO 945-1 >85%).
| PPAP-inlämningsnivå | Krav på dokumentation och provinlämning | Typiskt industri- och fordonsförsäljningsomfång |
|---|---|---|
Level 1 (PSW Only) |
Part Submission Warrant (PSW) and Appearance Approval Report (AAR) submitted to buyer. |
Bulk lågrisk standardkatalogkomponenter där gjuteriet har flerårigt historiskt godkännande. |
Level 2 (PSW + Samples + Limited Data) |
PSW, produktprover och dimensionella layoutresultat skickas till köparen; fullständig dokumentation bevarad på gjuteriet. | Mindre reparationer av verktygsmönster eller icke-kritiska strukturella fästen där metallurgin förblir oförändrad. |
Level 3 (Complete Dossier + Samples — The Standard) |
Complete 18-Element PPAP Dossier (PFMEA, Control Plan, Gage R&R, CMM Layout, OES lab reports, NDT charts) submitted alongside 5 FAI parts. |
Mandatory STALFE Standard for all new casting contracts, Indian foundry qualification (PRO-001), and automotive engine/pump housings. |
Level 4 & Level 5 (On-Site Foundry Audit Required) |
Level 4: Custom dossier agreed by customer. Level 5: Complete dossier reviewed and verified on-site at the foundry manufacturing plant by customer auditor. |
Obligatorisk för säkerhetsgjutgods för högspänningsflyg, undervattens API 6D kärntrycksventiler eller ombord på en helt ny utländsk gjuteripartner. |
