6-Stage Quality Control for OEM/ODM Sock Production

Before knitting, incoming yarn and required material documents are reviewed against the order specification. Composition, color and testing requirements are confirmed according to the buyer's product and target market.

During knitting, operators and quality staff check construction, pattern accuracy, size consistency and visible defects. Inspection frequency and acceptance criteria are defined by the production and quality plan.

The linking stage is checked for seam thickness, skipped stitches, alignment and visible workmanship issues. The inspection method and sampling level are aligned with the approved specification.

After boarding (heat-setting on metal forms), we check each sock for correct size, shape, and surface finish. Socks that are stretched, wrinkled, or don't match the foot form are pulled. This is also where we verify color consistency across the production batch.

Finished goods are checked for dimensions, weight, color, labeling and packaging. The applicable sampling plan, acceptance limits and reinspection route are confirmed with the buyer for each order.

Before goods leave the factory, we perform a final check: correct quantities, proper packaging, carton markings, and shipping documentation. We also take photos of the container loading process and share them with the client as proof of shipment condition.
