Beyond ISO9001: Yibo Shiguang’s 27 Quality Control Nodes Fully Disclosed For B2B clients

especially large-scale partners like hotel chains and cross-border brands—a rigorous, traceable quality management system is non-negotiable. Going far beyond ISO9001 certification, Yibo Shiguang implements 27 strict quality control (QC) nodes throughout production, from raw material inbound to finished product delivery, all fully transparent for client oversight. Key checkpoints include 3-layer raw material inspections (e.g., verifying foam density ≥35kg/m³ and spring wire diameter accuracy within ±0.05mm), in-process tests for spring rebound rate and fabric abrasion resistance, and final evaluations of mattress firmness consistency and structural stability. Each node generates traceable data records, ensuring any deviation is promptly addressed. We also conduct random sampling for 50,000-cycle pressure tests and formaldehyde emission detections, adhering to global standards. This lean production and traceable QC system eliminates quality risks at every step. For major clients, it provides irrefutable proof of reliability—addressing their core concern of consistent product quality across bulk orders. By opening up our QC process, we build unshakable trust, positioning ourselves as a supplier that prioritizes precision and accountability.
