How V5 Ultimate runs a polymer compounder, end to end.

Plastics compounders and converters supply downstream regulators directly: 21 CFR 174–179 (food-contact substances), EU 10/2011 with the framework Reg 1935/2004 and the GMP Reg 2023/2006, UK SI 2012/2619 — each requires the compounder to issue a written Declaration of Compliance (DoC) per resin lot or grade, listing every monomer, additive, colorant and processing aid, with the relevant authorisations and any specific migration limits (SML) and dual-use additive constraints.

Medical-grade resins add USP <87> / <88> biological reactivity, ISO 10993-1 evaluation strategy, animal-derived material declarations where applicable, and full sub-tier additive disclosure to the device OEM's design history file.

V5 Ultimate treats every resin lot, every additive dispense, every extruder cycle, every QC test (MFI, color ΔE, moisture, migration where in-house) and every DoC / CoA / MoA issued as part of the same immutable ledger. A customer DoC challenge is a query. The food-contact or medical-grade claim is bound to the recipe and the lot — it cannot drift.

Every node carries forward resin lot, work order, operator, extruder, food-contact / medical-grade status and customer-segregation context from the node before it. Nothing is re-keyed.

EU 10/2011 Art. 15 requires written supporting documentation behind every DoC. V5 holds every resin supplier as a structured object: scope by grade × site, food-contact statement with monomer / additive list and authorisations, medical-grade attestation where applicable (USP class VI, ISO 10993-1 strategy), animal-derived material declaration, REACH SVHC status, conflict-minerals where additives include metals, ISO 9001 / ISO 15378 / IATF certificates.

Re-qualification is calendar-driven and portal-led; an expired food-contact statement blocks goods-in automatically. Risk scoring drives the depth of incoming inspection.

The receiver scans the ASN, weighs against PO, captures the supplier lot, MoA, food-contact / medical-grade attestation, and photographs condition. V5 mints a goods-receipt lot ID at that moment.

Identity verification — visual, FTIR for polymer identity, melt-flow index (MFI / MVR) on the kiosk, moisture, ash, residual monomer where required — runs on the same kiosk. Results link to the receipt lot, instrument, analyst e-signature and supplier MoA.

V5 maintains silo / Gaylord attributes: polymer family, food-contact / medical-grade flag, customer segregation (some OEMs require dedicated silos), color / additive history (relevant for changeover), moisture state. The pick list shown to the picker only includes locations compatible with the work order. FIFO is enforced; overrides require reason + dual e-sig.

Each compound recipe holds: BOM with base resin, additives (stabilisers, slip, anti-block, plasticisers, colorants), masterbatch, regrind allowance per customer spec, with food-contact / medical-grade flag per line; extruder routing with temperature profile, screw speed, vacuum, die geometry; in-process control plan (MFI, color ΔE, moisture, pellet dimension, contamination); pellet packaging routing; DoC template, MoA template, customer-specific CoA template, and locked label artwork.

Effectivity is two-signature: a formulator signs the change, QA signs the regulatory impact (does this change re-trigger a migration test? does it invalidate the existing DoC?). New WOs pick up the new revision; in-flight WOs keep their snapshot.

If the recipe is revised mid-shift, the work order keeps the snapshot it was released against. The auditor or the customer's quality engineer sees exactly the formulation this lot was built to, with the sha256 of the snapshot recorded against release.

Dispense is scale-stream — the kiosk reads loss-in-weight feeders, verifies % within tolerance, captures the additive lot scan and operator e-signature. Out-of-tolerance trips an in-process deviation. The extruder step shows the recipe's temperature profile, screw speed and vacuum; live readings are captured continuously; out-of-spec excursions auto-flag.

Grade and customer changeovers are explicit, signed gates. A change from a colored grade to a clear grade, or from a non-medical to a medical grade, requires a documented purge cycle with purge yield, transition-pellet quarantine and a clear-pellet verification before the next WO releases.

Sampling plans run on a schedule, not a reminder. Test instruments stream readings into the same kiosk. OOS auto-opens a deviation, holds the lot, and notifies QA. Trending across lots surfaces drift before it becomes scrap or a customer rejection.

A single register categorises by event type. Root-cause uses structured templates. CAPAs link to the deviation, affected lots, operators, equipment, customer complaints, and where applicable the customer's 8D response.

Bag / Gaylord / silo labels carry product / grade name, lot, manufacture date, food-contact / medical-grade flag, net weight and customer reference. The DoC (per EU 10/2011 Art. 15) is generated automatically per lot — listing every monomer, additive, SML compliance, dual-use additive constraints, and where the user must verify FCM-compliance downstream. The MoA carries the QC results bound to the work order; the CoA serves the customer's incoming-inspection requirements.

Review-by-exception is only safe if the record is complete and immutable. V5's batch record is built from the ledger as the line runs. The QA reviewer's queue surfaces only items the system can't auto-clear. Release requires two qualified e-signatures, both identity-verified, both bound to the snapshot.

Every shipment ships against an ASN that carries lot codes. When a recall trigger fires — internal QA disposition, additive supplier withdrawal, customer field failure, downstream FCM compliance event — V5 walks the ledger in both directions in seconds: every pellet lot made from this additive lot, every customer DC it shipped to, every adjacent lot that shared the extruder.

The customer-notification packet, the 8D response, the regulator response file all assemble from the same ledger.

Context, interested parties, scope, processes, risks and opportunities, objectives — all live in V5 as structured records. Management review pulls automatically from the ledger.

Draft → Review → Approved → Effective → Periodic Review → Superseded / Retired. Two qualified signatures effect every release.

V5 maintains a training matrix per role × line × grade. Medical-grade and food-contact training are bounded; expired courses lock the operator out of the relevant kiosk action.

Every batch's quality signals, every CAPA, every supplier scorecard, every internal-audit finding, every customer complaint, every PPM — all stream into the management-review workspace as they happen.

V5's audit module schedules internal audits and external audits (ISO 9001, ISO 15378, IATF, customer 2nd-party). When a customer's quality engineer arrives, the request list — DoCs, MoAs, last three months of MFI / ΔE trends, corrective actions — is a query, assembled and printable in minutes.

Migration / extractables hazards are identified per recipe, per intended use (food simulants under EU 10/2011, biological reactivity under USP). Each hazard gets a control (formulation choice, in-process verification, finished-product test, customer disclosure), and a verification cadence.

Metal detector / X-ray on the pellet line, black-spec lab count per WO, screen-pack change schedule with screen-life tracking, gel count on film grades, full extruder tear-down cadence — all assembled into one programme with a calendar and an audit trail.

V5 holds purge procedures per from-grade × to-grade pair, with purge compound, screw speed, temperature, purge mass, transition-pellet handling, and the verification check (visual clear-pellet, color match, MFI verification, contamination check). Sanitation events are kiosk-led; results bind to the equipment record.

Loss-in-weight feeders, extruder temperature probes, vacuum gauges, MFI instruments, spectrophotometers (for color ΔE), moisture analysers, scales, metal detectors — each is a tracked asset with calibration interval, certificate, tolerance, and an out-of-tolerance impact-assessment that triggers a back-look.

Intake captures customer, complaint type (MFI off, color ΔE, contamination, moisture, dimensional, food-contact challenge), severity, affected part. V5 binds the complaint to the lot, surfaces adjacent lots on the same extruder, and trips a deviation if pattern crosses a threshold.

Every signed event carries the actor's verified identity, signature meaning, time, and a sha256 of the record. The signature row is append-only. PDF renders are deterministic from the snapshot.

DoCs per lot, MoAs, CoAs, migration / extractables reports, animal-derived material statements, REACH SVHC communications — all on the portal. Audit-trail of who downloaded what is automatic.

A typical plant onboards in 4–8 weeks: master data import (grades, recipes, customers), supplier compliance file migration, kiosk training, parallel-run validation, cutover.
