QUALITY ASSURANCE SYSTEMS
At Norvic International, quality isn't just a compliance stamp—it's an operational guarantee. We manufacture conveyor belts in strict alignment with DIN 22102, ISO, and IS international standards, ensuring premium durability.
1. Raw Materials Inspection
Every batch of raw natural rubber, SBR, and Nitrile polymers is tested for moisture, viscosity, and chemical purity. Polyester-nylon carcass fabrics undergo thermal-shrinkage checks.
2. In-Process Curing Monitors
During vulcanization, curing temperatures, pressure, and transit speeds are tracked in real-time. Any thermal deviation triggers automatic line halts to prevent under-cured zones.
3. Laboratory Failure Testing
Post-vulcanized roll samples are subjected to destructive rotating cylinder tests for abrasion loss, multi-ply adhesion peel tests, and flame-cabinet thermal retardancy checks.
PHYSICAL COMPOUND PARAMETERS
Our standard laboratory parameters represent verified maximum limits, satisfying global industrial procurement guidelines.
Verified Cover Property Standards
Verified B2B Data
Third-Party Inspection Rights
Norvic International supports and facilitates customer-commissioned third-party inspections (e.g., SGS, Bureau Veritas, Intertek) for raw material verification and physical property inspection at our dispatch terminal before final ocean crating.
