OEM/ODM Dehumidifier Box Manufacturing Process

Phase 1: Requirement & Solution Phase

Initial Consultation & Specification Brief

1. • Determine key technical requirements: absorbent capacity (e.g., 400ml, 500ml, 800ml), raw material formulation (Calcium Chloride flakes/pellets, fragrance added, active carbon, anti-mold agents).
   • Confirm target markets, required certifications (REACH, RoHS, SDS), and budget range.
2. OEM vs. ODM Path Selection
   • OEM Path (Original Equipment Manufacturer): Customer provides existing design specs, container molds, and packaging designs.
   • ODM Path (Original Design Manufacturer): Factory handles custom container shape/mold engineering, formula customization, moisture-absorption rate fine-tuning, and structural design.
3. Customization Specification
   • Box & Lid: Plastic resin selection (PP/PET), container color matching, lid structure (breathable mesh/slotted), and tamper-evident foil lid customization.
   • Internal Structure: Single chamber vs. dual-chamber moisture separation, grid tray design to prevent leakage.
   • Private Label Packaging: Aluminum foil sealing film print, outer color box design, shrink-wrap options, display packaging (PDQ), and carton marking.

Phase 2: R&D, Prototyping & Sampling

4. Mold Engineering & Prototyping
   • For ODM: 3D design rendering, CAD modeling, rapid 3D printing prototyping, and plastic injection mold building.
   • For OEM: Rapid sample prep using existing molds.
5. Sample Testing & Validation
   • Laboratory stability testing, moisture absorption capacity measurement, seal strength test (foil seal leak protection), and transport drop tests.
   • Customer receives golden samples for final physical and functional sign-off.

Phase 3: Mass Production & Quality Control

6. Raw Material Procurement & Inspection
   • High-purity Calcium Chloride
   • purity and moisture-content verification.
   • Food-grade / durable PP plastic granule testing.
   • Breathable membrane and sealing foil quality audit.
   • Automated Manufacturing Workflow
   • Step A: Plastic Injection Molding  – Molding precise container bodies, inner filter trays, and top covers.
   • Step B: Automatic Filling  – Dosing exact weights of desiccants (calcium chloride, fragrance beads, activated carbon).
   • Step C: Ultrasonic & Thermal Sealing – Heat-sealing the breathable film and printed aluminum foil lid to guarantee zero leakage prior to use.
   • Step D: Assembly & Outer Packaging – Snapping top lids, applying private label stickers, shrink-wrapping, and packing into export cartons.
   • In-Line & Final Quality Assurance
   • Net weight automated check-weighing.
   • Sealing integrity pressure testing (preventing leakage during ocean transit).
   • Visual inspection for plastic flashes, printing alignment, and packaging errors.
   • Phase 4: Logistics & After-Sales
   • Export Packaging & Palletization
   • Carton drop-resistance testing, moisture-proof stretch wrapping, and palletization configured for optimal shipping container space utilization.
   • Customs Clearance & Global Shipping
   • SDS (Safety Data Sheet) and transport risk assessment compliance verification for sea/air freight.
   • FCL (Full Container Load) or LCL shipping to global ports or Amazon FBA warehouses.
   • Post-Sales & Continuous Optimization
   • Delivery follow-up, client feedback collection, and order replenishment scheduling.
