Series Production Control for OEM Silicone Hose Projects
After PPAP formal approval and SOP release, Hotop runs serial silicone‑hose programs under disciplined Control de producción en serie. 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: muestras de oro, plan de control de producción, AMEF, especificaciones de materiales y parámetros de proceso validados. No se permiten ajustes informales en el proceso fuera de línea..
In-Line Quality Control Executed against Approved Control Plan
- Verificación de material entrante: cada lote de compuesto de silicona, La tela de refuerzo y el material del revestimiento se inspeccionan según las especificaciones y el CoC del proveedor se mantiene en el archivo..
- Monitoreo en proceso: 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.
How this page fits within your OEM project sequence
This process takes effect post-SOP, after completion of Flujo de trabajo OEM, Estampación & Acuerdo de confidencialidad alignment and full sign-off on Entregables del APQP. All quality-control activities in series production are traceable back to documentation agreed in the APQP-PPAP phase.
