Your Global Partner in CSA & CAC Solutions
Quality Control
Strict Process. Stable Quality. Trusted Performance.
At Zhengzhou Xinmi Melting Co., Ltd., we regard quality as the foundation of long-term cooperation. As a manufacturer specializing in CSA cement and calcium aluminate cement, we have established a complete quality control system covering raw material inspection, in-process control, final testing, and traceability. Every batch we deliver is consistent, reliable, and meets both domestic and international standards.
Strict Raw Material Control
All raw materials are sourced from certified and stable suppliers. Each incoming batch is subject to rigorous inspection, including chemical composition analysis, moisture content, fineness, and impurity control. This ensures a stable foundation for high-performance cement products.
Full-Process Quality Monitoring
Throughout production, we implement standardized operating procedures and real-time monitoring. Key indicators such as setting time, compressive strength, expansion stability, and mineral phase composition (e.g., ye'elimite, CA, CA₂) are closely tracked to ensure consistency and control deviation within strict tolerances.
In-House Laboratory Testing
Our in-house laboratory is equipped with advanced testing instruments such as XRD, XRF, laser particle size analyzer, and strength testers. Before delivery, every batch undergoes a full set of tests, including:
- Chemical composition
- Strength development at various ages (1h, 3h, 1d, 3d, 28d)
- Setting time and expansion rate
- Mineral phase identification
Final Inspection & Traceability
Each order is subject to final inspection before shipping. We verify packaging integrity, labeling accuracy, and batch number consistency. A complete set of documents—including the Test Report, TDS, MSDS, and Certificate of Analysis—is provided with each shipment for full transparency and traceability.
Commitment to Consistency & Improvement
We continuously collect and review production and testing data, conduct internal audits, and incorporate client feedback to refine our quality system. Our goal is not only to meet standards—but to deliver consistency batch after batch.
With uncompromising quality control, we deliver materials that perform with consistency—helping your projects succeed from start to finish.
