Standard Requirements:

• Precise control of precious metal content (ppm or g/L level);

• Uniform distribution to avoid local over- or under-concentration;

• Strict control of sintering temperature and time to ensure high-temperature resistance.

3. Catalytic Converter Assembly

• Secure the coated catalyst in the housing to ensure uniform airflow through the catalyst layer; • Install high-temperature, corrosion-resistant gaskets to ensure leak-free interfaces;

• Test pressure drop and exhaust gas purification efficiency to ensure compliance with customer and regulatory requirements.

III. Quality Control Standards

1. Raw Material Inspection: The carrier pore size, surface area, and chemical composition must meet design requirements;

2. Coating Uniformity Testing: Optical or X-ray inspection techniques are used to ensure uniform distribution of the precious metal;

3. High-Temperature Resistance and Thermal Cycling Testing: Ceramic and metal carriers must undergo multiple cycles of high-temperature cycling to ensure long-term stability;

4. Exhaust Gas Purification Efficiency Testing: CO, HC, and NOx conversion rates meet standard requirements;

5. Mechanical Strength and Vibration Resistance Testing: Ensure the catalyst does not break or fall off during transportation and use. ⸻

IV. Customization Advantages

• Highly Targeted: Customized design based on vehicle model, engine power, and emission standards;

• High Efficiency and Environmental Protection: Optimizing precious metal usage improves exhaust purification efficiency and reduces costs;

• High Reliability: Strict process control and testing ensure product resistance to high temperatures, vibrations, and a long lifespan;

• Traceability: Each batch of product is accompanied by production records and quality inspection reports for easy after-sales and regulatory oversight
