Hotop executes custom silicone hose OEM projects following APQP-aligned development discipline, designed for automotive Tier 1 / 階層 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 your 2D drawing, 3D CAD, specification sheet or reference sample. Our engineering and quality team reviews application conditions, media compatibility, temperature range, 圧力定格, 許容範囲, 色, 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.
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.
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.
We produce pre-production samples for your bench, 脈, 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.
We prepare and submit PPAP package (default Level 3, adjustable per your SQE requirement). PPAP approval is a mandatory gate before release to series production. Approved golden samples and control plan become the baseline for all future production.
After PPAP sign-off, プロジェクトがSOP用に正式にリリースされる. すべてのプロジェクト文書, 制御計画, SPCルール, 材料仕様と変更ルールは当社の生産および品質チームに引き渡されます。. この時点から, プログラムは当社の管理下にあります シリーズ生産管理 トレーサビリティのプロセス, ECN管理, インライン検査と納品調整.
ワークフロー調整後, 私たちのことを見直してください ツーリング & NDA 所有権に関する条件, 機密保持と専用ツールのガバナンス. PPAPの準備ができたら, 参照 APQP の成果物 品質パッケージの全範囲に対応. SOPが開始されると, 私たちの シリーズ生産管理 安定した供給を維持する体制. ブラウズ OEM事例 当社が納入した同様のシリコンホースプログラムの参考用.
