QC · Quality Control

A comprehensive quality system with tiered inspections—from incoming materials and in-process control to pre-shipment—ensures every pair consistently meets specification.

Quality Control Flow

On-site Full Inspection

Every pair is inspected one by one. Appearance and construction are checked against specifications; any non-conformity is immediately isolated and re-inspected.

Sampling Inspection

Inbound and finished goods are sampled by AQL per lot to verify batch stability and consistency.
