OEMシリコンホースプロジェクトのシリーズ生産管理

After PPAP formal approval and SOP release, Hotop runs serial silicone‑hose programs under disciplined シリーズ生産管理. This framework executes the approved Production Control Plan from APQP deliverables, governing quality inspection, engineering change governance, full‑chain traceability, nonconformity resolution and on‑time delivery for long-term Tier 1 / Tier 2 serial projects.

Core Governance Rules for Serial Production

All production activities strictly follow the baseline documents locked during APQP-PPAP: golden samples, production control plan, PFMEA, material specifications and validated process parameters. No informal offline process adjustments are permitted.

In-Line Quality Control Executed against Approved Control Plan

• Incoming material verification: every batch of silicone compound, reinforcement fabric and liner material is inspected against specification with supplier CoC retained on file.
• In‑process monitoring: key manufacturing parameters for mandrel forming, ply layup and curing are logged; first-piece, shift-middle and last-piece inspections are performed per sampling rules.
• Final dimensional & visual inspection: critical characteristics defined in customer drawings are measured with calibrated gauges.
• SPC data collection for special characteristics to detect process drift ahead of nonconformity occurrence.

ECN / Engineering Change Management

All product, material or process modifications after SOP go through formal ECN workflow:

• Change request submission & risk assessment (PFMEA update where applicable)
• Customer review & formal written approval
• Trial production run and validation testing
• Re-PPAP submission if required by customer SQE
• Controlled cut-over to revised specification, with clear old-part / new-part phase-out management.

No product or process change is implemented without documented customer consent.

End-to-End Lot Traceability

Each production lot carries unique traceability identifiers linking finished silicone hoses back to:

• Raw‑material batch certificates
• Mandrel / tooling maintenance records
• Production shift & process log
• In‑process and final inspection reports Traceability records are archived to satisfy IATF‑aligned retention requirements for automotive component supply.

Non-Conformity & Corrective-Action Mechanism

• Non-conforming units are strictly segregated, labelled and quarantined to prevent mixed shipment.
• Deviation concession requests are submitted for customer written approval if conditional acceptance is required.
• For field complaints or major internal quality events, we launch formal 8D problem-solving: containment actions, rootcause analysis, permanent corrective-actions, verification and PFMEA / Control Plan updates to prevent recurrence.

Serial-Supply & Delivery Coordination

• Capacity planning aligned with customer rolling forecast; JIT‑oriented order execution supported for stable serial programs.
• Batch‑wise packing and labelling matching customer receiving requirements.
• Dedicated project engineer remains assigned throughout series‑production phase as single‑point‑of‑contact for quality, change and delivery queries.
