We have established a complete quality management system, with five quality inspection links from raw material procurement to finished product delivery:
Raw material inspection (to ensure that mineral wool and additives meet environmental protection and performance requirements)
Inspection during production (real-time monitoring of board density, thickness, and pattern consistency during the production process)
Semi-finished product sampling (checking intermediate indicators such as board core structure and moisture content)
Finished product full inspection (each board is tested for flatness, size, tolerance, pattern and color consistency)
Final re-inspection before packaging (confirm that there is no damage, no color difference, and the label and quantity are accurate)
All factory products are accompanied by inspection batch numbers and inspection records to ensure that each board meets the standards.
