Production Process Quality Control

At Obibi, quality is not just a step in our process—it's the foundation of everything we do. Our comprehensive Quality Control system is integrated into every stage of production, from raw material inspection to final packaging. We understand that when it comes to baby products, there is zero room for compromise. That's why we've developed one of the most rigorous quality assurance protocols in the industry, ensuring that every product bearing the Obibi manufacturing stamp meets the highest international standards for safety, durability, and comfort.

Our multi-layered QC approach combines advanced technology with highly trained quality inspectors who bring decades of specialized experience in infant product manufacturing. This document outlines our detailed quality control procedures throughout the entire production workflow.

Our Comprehensive QC Process Flow

1

Raw Material Inspection

Quality begins at the source with thorough fabric and component testing

2

Pre-Production Testing

Prototype validation and production sample approval

3

In-Process Quality Control

Real-time monitoring during cutting, sewing, and assembly

4

Final Random Inspection

AQL-based comprehensive product examination

5

Laboratory Testing

Advanced safety and performance verification

Stage 1: Raw Material Quality Control

Critical Control Point

Before any production begins, all incoming materials undergo rigorous inspection in our dedicated textile laboratory.

Fabric Quality Testing

Composition Verification

Using FTIR spectroscopy to verify fiber content matches supplier specifications and organic certifications.

Standard: ±2% tolerance

GSM/Weight Check

Digital scale measurement to ensure fabric weight consistency across batches.

Standard: ±5% tolerance

Color Fastness Testing

Testing resistance to washing, rubbing, perspiration, and light exposure.

Standard: AATCC 61, ISO 105-X12

Dimensional Stability

Measuring shrinkage after multiple wash cycles to ensure consistent sizing.

Standard: ±3% maximum shrinkage

Safety & Compliance Testing

Chemical Safety Screening

Testing for restricted substances including formaldehyde, heavy metals, and phthalates.

Standard: REACH, CPSIA, Oeko-Tex 100

Flammability Testing

Ensuring all fabrics meet strict flammability requirements for children's sleepwear.

Standard: 16 CFR Part 1610, EN 1103

pH Value Testing

Verifying fabric pH is within safe range for baby's sensitive skin.

Standard: pH 4.0-7.5

Component Safety

Testing buttons, snaps, and zippers for lead content and mechanical safety.

Standard: EN 71-1, ASTM F963

Stage 2: Pre-Production Quality Control

Prevention Focus

Identifying and resolving potential issues before mass production begins.

Every new design undergoes comprehensive prototype testing to verify design integrity, functionality, and safety.

Pattern Accuracy

  • Digital pattern verification against technical specifications
  • Size grading accuracy across all sizes (preemie to 24M)
  • Seam allowance consistency check

Construction Analysis

  • Stitch type and SPI (stitches per inch) verification
  • Seam strength testing on tensile machine
  • Reinforcement point validation

The first articles produced from production lines undergo meticulous inspection and client approval.

Measurement verification against size chart
Color matching to approved standards
Functionality testing (zippers, snaps, buttons)
Label placement and accuracy verification
Packaging and presentation review

Stage 3: In-Process Quality Control

Continuous Monitoring

Real-time quality surveillance throughout the manufacturing process.

Cutting Process QC

1
Fabric Layering Inspection: Checking for tension consistency, alignment, and ply count accuracy.
2
Cutting Precision: Automated optical scanning to verify cut pieces match digital patterns within 1mm tolerance.
3
Notch and Mark Verification: Ensuring all alignment marks are accurately cut for proper assembly.

Sewing & Assembly QC

1
First Piece Inspection: Each operator inspects the first piece from each batch against sealed sample.
2
Line Auditing: QC patrols conduct hourly checks of 5 random pieces from each production line.
3
Stitch Quality Control: Monitoring stitch density, tension, and consistency using calibrated gauges.

Immediate Corrective Action Protocol

Any defect identified during in-process inspection triggers an immediate halt to the production line. The issue is documented, analyzed, and corrected before production resumes. This prevents batch-level quality issues and ensures consistent output.

Stage 4: Final Random Inspection (AQL Based)

Statistical Quality Assurance

Comprehensive examination of finished products using internationally recognized AQL sampling standards.

Our AQL Standards

Critical Defects
AQL 0.0%
Safety issues, sharp edges, choking hazards
Major Defects
AQL 1.5%
Functional issues, poor workmanship
Minor Defects
AQL 4.0%
Cosmetic issues, minor stitching variations

Final Inspection Checklist

Visual Inspection

  • Fabric flaws, stains, or discoloration
  • Print/embroidery alignment and quality
  • Overall workmanship and neatness
  • Thread ends properly trimmed

Measurement Verification

  • Garment dimensions against specification sheet
  • Symmetry check (sleeves, legs, panels)
  • Neck and armhole circumference
  • Label placement accuracy

Function Testing

  • Zipper/snap/button operation
  • Elastic tension and recovery
  • Closure security and durability
  • Overall garment functionality

Stage 5: Laboratory Testing & Certification

Scientific Validation

Advanced testing in our in-house laboratory and third-party certified facilities.

Performance Testing

Wash Durability Testing

Subjecting products to multiple wash cycles (5, 10, 25 cycles) to assess color retention, dimensional stability, and overall durability.

AATCC 135, ISO 6330

Seam Strength Testing

Using tensile testing machines to measure seam strength and ensure they withstand normal wear and tear.
