QC Process

Quality at Every Stage

Our in-house quality control team inspects at six critical checkpoints — from raw materials through to pre-shipment final inspection.

Incoming Material Inspection

Every roll of fabric, zipper reel and hardware batch is tested before entering production.

  • GSM weight check
  • Colorfastness test
  • Tensile strength
  • Hardware plating durability

Pattern & Cutting QC

Pattern accuracy verified against tech pack before any cutting begins.

  • Dimension accuracy ±0.5 cm
  • Grain direction check
  • Nesting efficiency
  • Cut bundle labelling

In-Line Sewing QC

QC inspectors walk the line every 2 hours checking stitch quality and consistency.

  • Stitches per inch (SPI)
  • Seam strength
  • Thread colour match
  • Symmetry check

Hardware & Zipper Testing
