Analysis of the whole process of hardware tool storage bag production——From material selection to quality inspection, every stitch is precisely controlled
- Material selection and pretreatment
Core raw materials:
Fabric: 1680D Oxford cloth (tear-resistant) + TPU waterproof coating (weather resistance test passed)
Lining: high-density EVA foam (buffering and compression resistance) + scratch-resistant nylon cloth (tool protection)
Accessories: YKK zipper (100,000 opening and closing tests), high-strength nylon webbing (load-bearing ≥50kg)
Pretreatment link:
Fabric waterproof coating spraying (constant temperature workshop to ensure uniform coating)
Pre-shrinkage treatment before fabric cutting (reduce the deformation rate of finished products)
- Precise cutting of intelligent cutting bed
CAD plate making: design the pattern according to the size of the tool bag and optimize the fabric utilization rate (up to 92%)
Laser cutting: error ≤0.5mm, ensuring accurate shaping of key parts such as pockets and handles
Residual material recycling: unified treatment of waste materials, in line with REACH environmental protection standards
- Modular sewing process
Core process:
Layered sewing:
The main compartment adopts three-needle six-thread process (enhanced seam strength)
Tool pockets are reinforced with hemming strips (to prevent tools from wearing fabric)
Functional parts assembly:
Embedded sewing of magnetic buckles (no exposed thread ends)
X-shaped cross stitching at the connection between shoulder straps and bag body (load-bearing upgrade)
Special treatment:
High-frequency hot pressing technology (making transparent PVC label window)
Ultrasonic welding of reflective strips (no risk of pinhole leakage)
- Installation of functional parts
Hardware accessories: D-rings and buckles pass the tensile test (≥80N)
Battery compartment design: fire-retardant liner + independent circuit compartment (UL certified)
Customized service: LOGO adopts thermal transfer/embroidery technology (supports Pantone color matching)
- Full-link quality inspection
| Stage | Inspection items | Standard |
| Raw materials | Fabric wear resistance | ASTM D4157-13 (5000 Martindale tests) |
| Semi-finished product | Semi-finished product Suture tension value | ≥200N (simulating full tool load) |
| Finished product | Waterproof performance | IPX6 (spray test for 30 minutes) |
| Before packaging | Before packaging Metal parts salt spray test | 48 hours no rust (ASTM B117) |
- Environmental protection and compliance guarantee
Complete certification: CE (EU), CPC (USA), OEKO-TEX® (non-toxic certification)
Packaging solution: degradable PE bag + recycled paper hangtag (supports customized environmental slogans)
Social responsibility: Produced in BSCI certified factories, rejecting child labor/forced labor
