Testing Laboratory
Our quality inspection gear isn’t just about meeting standards—it’s about redefining them. For 45 years, these machines have been our most trusted allies in upholding the quality that makes BAO a name to rely on in heavy industries. They scan, they test, they validate with unwavering accuracy, ensuring that every conveyor belt we produce is a symbol of durability and dependability. We don’t just inspect products; we honor our commitment to quality—one precise measurement, one rigorous check, one promise kept at a time.
DIN Abrasion Tester
This instrument measures the abrasion resistance of rubber by quantifying volume loss when a sample is rubbed against a standardized abrasive surface, essential for evaluating cover durability in conveyor belts.
Electronic Universal Testing Machine
This versatile machine performs tensile, elongation, adhesion, and compression tests on rubber and full belt samples, measuring key mechanical properties like strength and ply bonding.
Analytical Balance
This high-precision scale weighs samples accurately to 0.0001g, used for density calculations, abrasion loss measurement, and compound formulation verification.
Box-Type Muffle Furnace
This high-temperature furnace ashes rubber samples for filler content analysis or performs heat resistance tests on materials.
Constant Temperature Drying Oven
This oven dries rubber samples at controlled temperatures to remove moisture, preparing them for accurate testing and simulating aging conditions.
Mooney Viscometer
This device assesses the viscosity and scorch characteristics of unvulcanized rubber compounds by measuring torque on a rotating rotor, helping optimize processing behavior and material consistency.
