As a carbon black manufacturer, its quality management system should follow a series of requirements to ensure the stability of product quality and compliance with relevant standards. Here are some common requirements that may be included in a quality management system:

ISO Certification: Carbon black manufacturers usually strive to obtain ISO 9001 quality management system certification, which is an international standard that deals with quality management and quality assurance requirements. This certification ensures that companies establish and maintain a set of quality management procedures applicable to their products and services.

Product specifications and standards: Carbon black manufacturers need to develop and comply with a strict set of product specifications and standards to ensure product quality consistency and stability. These codes and standards can be national standards, industry standards, or customer-required standards.

Raw material control: white carbon black manufacturers need to establish effective raw material control procedures, including supplier evaluation, raw material procurement and reception inspection, to ensure that the raw materials used meet the quality requirements.

Production process control: manufacturers need to implement strict production process control to ensure that each process meets the requirements of the specification. This may involve the monitoring of process parameters, equipment calibration, preparation of work instructions and training.

Quality inspection and testing: Manufacturers should establish a sound quality inspection and testing system, including sampling inspection of products, physical performance testing, chemical analysis, etc., to verify whether the product meets the requirements of specifications and standards.

Defective product handling and traceability: The manufacturer shall establish reasonable defective product handling procedures, including classification, recording, analysis and corrective actions of defective products. In addition, the manufacturer should also be able to trace the production process of the product and the source of raw materials in order to investigate and solve problems when needed.

Customer complaint handling: manufacturers need to establish an effective customer complaint handling mechanism, respond to customer complaints in a timely manner, and take appropriate measures to solve the problem to improve customer satisfaction and product quality.
