OUR COMPREHENSIVE QUALITY CONTROL
At our manufacturing facility, quality is not just a standard — it is a commitment embedded in every stage of production. Our comprehensive Quality Control (QC) system ensures that every batch of filler and color masterbatch consistently meets the highest international standards and customer specifications.
Raw Material Inspection
Quality begins with strict control of incoming materials. All raw materials, including calcium carbonate (CaCO₃), polymer resins, pigments, and additives, undergo rigorous inspection before entering the production line.
• Verification of supplier certifications and compliance documents.
• Testing of key parameters such as particle size, moisture content, whiteness, and purity.
• Evaluation of melt flow index (MFI) and compatibility for carrier resins.
• Color consistency checks for pigments and additives.
Only materials that meet our strict acceptance criteria are approved for production
In-Process Quality Control
During production, our advanced monitoring systems and experienced technicians ensure stable processing and consistent product quality.
• Continuous supervision of dispersion quality and mixing uniformity
• Strict control of pelletizing process to ensure uniform size and shape
• Prevention of contamination through closed-loop production systems
• Any deviation is immediately corrected to maintain optimal production conditions
Finished Product Testing
Each batch of masterbatch is thoroughly tested before release to ensure it meets both internal standards and customer requirements.
• Physical Properties: pellet appearance, size uniformity, bulk density
• Mechanical Performance: tensile strength, elongation (when applicable)
• Thermal Properties: heat resistance and stability
• Dispersion Quality: evaluated through film/blown film testing
• Color Performance (for color masterbatch): color strength, ΔE value, consistency
• MFI Testing: ensuring processing compatibility
Only products that pass all quality checks are approved for shipment.
Laboratory & Testing Equipment
Our in-house laboratory is equipped with modern instruments to guarantee accurate and reliable testing results:
• Melt Flow Index (MFI) testers
• Spectrophotometers for color measurement
• Moisture analyzers

• Dispersion testing equipment (film/blown film machines)
All equipment is regularly calibrated to ensure precision and consistency.
Traceability System
• Batch identification from raw materials to finished goods
• Production records for each lot
• Retained samples for future reference
This ensures complete transparency and quick response in case of any quality-related inquiries.
