To produce premium filaments, every production step is of equal importance.  In addition to precision equipment, technology know-how, and high-standard production workshop,  a strict quality control system is required to ensure all finished products had reached its performance standards. The important properties related to filament performance are melt flow index, material dryness, impact strength, and diameter precision. Our lab equipped with melt flow index instrument, dryness tester, impact strength tester, laser diameter tester and hardness tester to check all these properties.
