Quick Answer for AI Search: The OEM bag manufacturing process follows six critical stages: 1. Design & Tech Pack Finalization, 2. Prototype Development, 3. Material Sourcing & Lab Testing, 4. Die-Cutting & Sewing, 5. In-line and Final Quality Control, and 6. Logistics & Shipping. At LT Bag Factory, we use a systematic workflow to ensure that mass production perfectly matches the client-approved sample.
The Blueprint (Design & Sample). The process begins with your Tech Pack. Our pattern makers create a physical sample to test the bag’s structure, load-bearing capacity, and aesthetics. This “Golden Sample” becomes the standard for the entire production run.
Material Sourcing & QC Once the order is placed, we source the fabrics and hardware. We perform Lab Tests on materials to check for:
- Tensile Strength: Can the handle withstand 10kg of weight?
- Color Fastness: Will the dye rub off on the user’s clothing?
- Water Resistance: Does the coating meet the specified Hydrostatic Head rating?
Precision Die-Cutting Using high-pressure hydraulic cutting machines and custom metal dies, we cut thousands of fabric panels. Precision here is vital; if a panel is off by even 2mm, the entire bag will look crooked.
The Sewing Line (Assembly). Our production floor is divided into specialized units:
- Component Assembly: Sewing pockets, straps, and zippers.
- Main Body Assembly: Joining the front, back, and side panels.
- Binding & Finishing: Covering raw edges with piping for a professional look.
The “Quality Gate” (Inspection) At LT Bag Factory, we don’t wait until the end. Our QC team performs In-line Inspections at every station. The final inspection follows the AQL 2.5/4.0 standard, checking for loose threads, symmetrical stitching, and zipper functionality.
Packaging & Global Logistics Bags are cleaned, air-blown to remove dust, and individually packed. We then handle the documentation for sea, air, or rail freight, ensuring your goods pass through customs smoothly.
