Specific Practices for Quality Assurance

Wholesale Activated Carbon Manufacturer


Raw Material Inspection

Prior to production, we meticulously inspect our raw materials for consistency and purity. This involves a series of checks such as moisture content analysis, carbon content verification, and material size grading. Our suppliers are required to meet our high standards, and we only proceed with materials that pass our strict acceptance criteria.

Preparation and Calibration

Our equipment is thoroughly prepared and calibrated before any production begins. This ensures that all machinery operates within specified parameters, delivering consistency in our production process. Calibration is conducted by certified technicians using calibrated instruments, adhering to international standards.


Continuous Monitoring

Throughout the production process, we maintain continuous monitoring to ensure that each phase meets our quality benchmarks. Parameters such as temperature, pressure, and reaction times are closely watched and adjusted in real-time to maintain optimal conditions.

In-process Sampling and Testing

Regular sampling and testing occur during production to monitor the quality of the activated carbon as it is being produced. This includes tests for adsorption capacity, surface area, and pore structure. Any deviations from our quality standards are immediately addressed by our production team.

Final production

Final Product Testing

Once production is complete, our activated carbon undergoes a final series of comprehensive tests. These tests are designed to confirm that the product meets all specifications such as particle size distribution, hardness, and bulk density. Only after passing these rigorous tests is the product packaged for distribution.

Packaging Integrity

We ensure that the packaging of our activated carbon provides adequate protection against contamination and damage during transportation. Our packaging materials are selected for their durability and are subject to strict quality control checks.

Traceability and Documentation

Each batch of our activated carbon is fully traceable, with detailed records maintained from raw materials to final product delivery. This documentation provides our customers with the assurance of quality and the ability to trace the product back through every step of its production.
