OEM Workflow for Custom Silicone Hose Projects

Hotop executes custom silicone hose OEM projects following APQP-aligned development discipline, designed for automotive Tier 1 / Aşama 2 and industrial serial programs. Our workflow locks requirements, mitigates design and process risks, delivers validated samples, completes PPAP approval, and transitions smoothly into stable series production.

Submit 2D/3D Drawings for DFM Review

Hotop Project Stages

1. teklif talebi & Requirement Lock

Submit your 2D drawing, 3D CAD, specification sheet or reference sample. Our engineering and quality team reviews application conditions, media compatibility, temperature range, basınç derecesi, tolerans, renk, reinforcement structure and material grade (MVQ, platinum-cured, fluorosilicone lined etc.). We clarify scope, tooling responsibility, sampling schedule and commercial terms before formal quotation. NDA can be activated upon request.

2. DFM Review & Feasibility Assessment

Design for Manufacturability review is our core upstream gate. We evaluate wall thickness, mandrel demolding, flash control, reinforcement alignment, end fitting geometry, shrinkage and dimensional stability. We issue DFM comments and recommended design adjustments to avoid rework during tooling trial and sampling.

3. Tooling Fabrication & First Trial

Once DFM is mutually approved, dedicated mandrels / tooling are manufactured per controlled drawing. We carry out first trial run, inspect as-built dimensions, surface finish and extrusion/molding consistency. Trial records and first-article data are retained in the project file.

4. Prototype Sampling & Doğrulama

We produce pre-production samples for your bench, nabız, burst, thermal cycling and system testing. All samples are traceable to material batch and trial record. We collect test results, address non-conformities and update the process before PPAP package preparation.

5. PPAP Submission & Customer Approval

We prepare and submit PPAP package (default Level 3, adjustable per your SQE requirement). PPAP onayı, seri üretime geçilmeden önce zorunlu bir geçiştir. Onaylanmış altın numuneler ve kontrol planı gelecekteki tüm üretimin temelini oluşturur.

6. SOP Sürümü & Seri Üretime Geçiş

PPAP imzalandıktan sonra, proje resmi olarak SOP için yayınlandı. Tüm proje belgeleri, kontrol planı, SPC kuralları, malzeme spesifikasyonları ve değişiklik kuralları üretim ve kalite ekibimize devredilir. Bu noktadan itibaren, program bizim denetimimiz altında yönetilmektedir Seri Üretim Kontrolü izlenebilirlik süreci, ECN yönetimi, in-line inspection and delivery coordination.

What We Control Across the Workflow

• Clear gate reviews between each phase; no uncontrolled forward skip
• Full document traceability for automotive IMDS and material declaration
• Single point project engineer assigned for your program
• Formal deviation and change request channel before and after SOP
• All records retained to meet IATF 16949 retention requirements

Next Step in Our OEM Program

After workflow alignment, review our Takımlama & Gizlilik sözleşmesi terms covering ownership, confidentiality and dedicated tooling governance. When PPAP is ready, refer to APQP Teslimatları for the full quality package scope. Once SOP starts, our Seri Üretim Kontrolü framework sustains consistent supply.
