Series Production Control for OEM Silicone Hose Projects

After PPAP formal approval and SOP release, Hotop runs serial silicone‑hose programs under disciplined Controle de produção em série. 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: amostras de ouro, plano de controle de produção, PFMEA, especificações de materiais e parâmetros de processo validados. Nenhum ajuste informal de processo off-line é permitido.

In-Line Quality Control Executed against Approved Control Plan

• Verificação de material recebido: cada lote de composto de silicone, o tecido de reforço e o material do forro são inspecionados de acordo com as especificações do CoC do fornecedor mantido em arquivo.
• Monitoramento em processo: principais parâmetros de fabricação para formação de mandril, ply layup and curing are logged; first-piece, shift-middle and last-piece inspections are performed per sampling rules.
• Dimensional final & inspeção visual: as características críticas definidas nos desenhos do cliente são medidas com medidores calibrados.
• SPC data collection for special characteristics to detect process drift ahead of nonconformity occurrence.

ECN / Gerenciamento de Mudanças de Engenharia

Todos os produtos, modificações de materiais ou processos após o SOP passarem pelo fluxo de trabalho formal do ECN:

• 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.

How this page fits within your OEM project sequence

This process takes effect post-SOP, after completion of Fluxo de trabalho OEM, Ferramentas & NDA alignment and full sign-off on Entregáveis ​​APQP. All quality-control activities in series production are traceable back to documentation agreed in the APQP-PPAP phase.
