Why Quality Inspection Matters for Your Pet Products

Pet product quality testing is fundamental to ensuring pet safety and brand reputation. KUDI PET has established a comprehensive quality control system that covers the entire process from raw materials to finished products, strictly adhering to international standards to ensure every product meets the safety requirements.

Our testing system focuses on three core dimensions:

Safety

Ensures the product is free of harmful substances and complies with international standards such as ASTM F963 and CPSIA.

Durability

Verifies product lifespan and reliability using professional testing equipment.

Functionality

Ensures the product meets its intended purpose and delivers stable, reliable performance.

Quality Control Workflow

(From Incoming to Shipment)

Unlike many suppliers, KUDI PET operates its own dedicated testing laboratory. Every instrument is calibrated regularly, every test is documented, and every result is traceable — from raw material incoming to finished goods outgoing.

Incoming Inspection (IQC)
- Spot checks of raw materials/critical components, color/size/critical performance.
  Key indicators: material composition, dimensional accuracy, and initial strength.
  Instrument support: standard light source, color-matching light box, and tensile testing machine (for random sampling).
In-Process Quality Control (IPQC)
- First article confirmation, inspection of critical processes (injection molding/assembly, etc.).
  Monitoring points: dimensional stability, assembly fit, and screen printing adhesion
  Instrument support: vibration testing (simulating transportation vibration), circuit board simulation testing, etc.
Final Inspection (FQC)
- Functional/appearance/quantity/packaging consistency.
  Test items: Lifespan, tensile strength, salt spray, aging, etc. (by product type)
  Instrument support: All 10+ instruments work together to provide official test reports.
Pre-shipment Check
- Packing list, markings, spot checks, and verification.
Nonconformance Handling
- Isolation, rework/scrap, corrective and preventative measures.
