Quality & Safety

Quality is the cornerstone of Yuncheng operations.

Quality is the cornerstone of Yuncheng operations. The company adheres to international standards during production, utilizing high standard raw materials and advanced manufacturing processes to ensure the highest product quality. Additionally, Yuncheng has established a comprehensive quality management system, overseeing every stage from design to after-sales service.

Full-Process Quality Control, Certified by Three Management Systems

We implement comprehensive quality control from raw materials to finished products, ensuring stable performance and reliable specifications for every batch.

Raw Material Control

All raw materials are tested before entering the factory; substandard materials are rejected on-site. Coconut shell raw materials are sourced from Philippines procurement base; coal-based raw materials are selected from premium anthracite and coking coal in Ningxia.

Process Control

Key parameters including grinding fineness and forming strength are inspected every shift. Carbonization and activation temperatures are monitored 24/7 with ±5°C accuracy.

Finished Product Testing

Complete performance test reports are provided, including iodine value, abrasion resistance, desulfurization value, and denitrification rate. 100% inspection ensures every shipped product meets standards.

Testing Equipment

Equipped with iodine value testers, hardness testers, BET surface area analyzers, atomic absorption spectrophotometers, and other complete testing instruments for full-range in-house testing capability.

Professional Team

Our quality control team is composed of experienced technical engineers and maintains long-term technical collaboration with Zhengzhou University Department of Chemistry, Southwest Research Institute of Chemical Industry, and other research institutions to continuously optimize testing methods and quality standards.
