Preferred Qualification

Only collaborate with suppliers certified by ISO 9001, strictly implementing the Supplier Qualification Control Procedure.

Dynamic Supervision

Annual factory audits + quarterly performance evaluations to ensure compliance with global standards such as REACH, FDA, and GB.

Zero-Defect Raw Materials

All raw materials must be accompanied by factory inspection reports or third-party test reports, with 100% re-inspection of key indicators upon arrival.

Physical and chemical Indicators

Particle size (laser particle size analyzer), moisture content (intelligent titrator), flash point (ASTM D93), viscosity (Brookfield viscometer), pH value, etc.

Performance Testing

Visual inspection (metallographic microscope), color difference (ΔE ≤1.0), glossiness (60° angle measurement), hardness (pencil hardness), thickness testing (Fisher coating thickness gauge), [hydrophobicity testing (water contact angle), etc.]{.mark}

Durability Validation

Salt spray corrosion test (5% NaCl), UV aging test, constant temperature and humidity test (85°C/85% RH), etc.

Authoritative Certifications

Certified by SGS, TUV, etc., complying with international regulations such as RoHS, REACH, and FDA.

Full Traceability

ERP system tracks the entire chain from raw material batches → production → logistics, enabling precise traceability within 15 minutes.

Intelligent Production

Automated control systems manage feeding sequence, feeding speed, stirring speed, etc., with anomaly alerts.

Real-time monitoring of reaction parameters (temperature, pressure), with automatic alarms for out-of-limit conditions.

Rapid Response

Root cause analysis for defects within 48 hours and closed-loop improvements (per the Nonconforming Product Control Procedure).

Customized Testing

Additional testing items tailored to customer requirements.

Joint Development

Provide formula optimization support to help customers reduce costs and improve efficiency.

Quality Commitment: Annual factory pass rate ≥99.8%, with customer complaints addressed within 24 hours.
