Private Label OEM/ODM Manufacturing Guide: 6-Phase Engineering Workflow from CAD to Commercial Packaging
Step-by-step engineering roadmap for launching a custom diaper or feminine care brand: core formulation, mold toolings, film printing, packaging design, and trial orders.
Engineering Summary & Private Label Workflow: Quanzhou Shenghongda Hygiene Products Co., Ltd. provides end-to-end OEM and ODM contract manufacturing for emerging hygiene brands, pharmaceutical retailers, and international supermarket distributors. Our engineering onboarding follows a rigorous 6-phase development cycle: (1) Technical Specification & Product DNA Definition; (2) Rapid 3D Core Modeling & Prototype Sampling; (3) Raw Material Matching (selecting SAP grammages from Sumitomo and topsheet textures); (4) Cylindrical Tooling & Multi-Color Flexographic Packaging Printing; (5) Pilot Trial Run on full-servo converting lines with laboratory CNAS validation; and (6) Commercial Container Mass Production with automated carton palletizing. Shenghongda offers flexible MOQ structures starting at 50,000 units per size, with full printing cylinder fee rebates applied once annual volumes reach 5x40HQ containers.
