I.Quality Assurance System

To meet the needs of market-oriented economic development and continuously improve product and service quality, Zibo Tongpu Vacuum Equipment Co., Ltd. places great importance on the establishment and operation of its quality management system. In 2017, the company obtained GB/T 19001-2016 / ISO 9001:2015 Quality Management System certification, laying a solid institutional and managerial foundation for the continuous improvement and stable enhancement of product quality.

In 2019, the company successively passed Occupational Health and Safety Management System certification and Environmental Management System certification, thereby establishing an integrated management system covering quality, environment, and occupational health and safety. The combination of an advanced and well-structured management system with a professional talent team and modern manufacturing equipment provides a reliable guarantee for the stable supply of high-quality products.

In strict accordance with the requirements of the ISO 9001 standard, the company systematically breaks down and implements quality management elements across all stages, including procurement, production, inspection, installation, and service. Centered on product manufacturing quality, installation quality, and service quality, the Quality Management Department focuses on the following key tasks:

1.Full-Process Inspection and Control

From raw material receipt to finished product delivery, multiple inspection and testing procedures are implemented to ensure the effective operation of all inspection activities and achieve comprehensive control of product quality throughout the entire process.

2.Management of Inspection and Measuring Equipment

All inspection, measuring, and testing equipment is centrally managed, regularly calibrated, and properly maintained to ensure the integrity, accuracy, and reliability of inspection data.

3.Inspection Status Identification

Products at different inspection stages are clearly identified and effectively distinguished to prevent confusion or misuse, ensuring that nonconforming products are not transferred to subsequent processes or delivered for use.

4.Control of Nonconforming Products

Strict procedures are enforced for the evaluation, segregation, and disposition of nonconforming products to ensure they are effectively controlled and properly handled.

5.Quality Records and Traceability

Complete quality inspection and record files are established for key components and critical processes, ensuring full traceability of product quality.

6.Quality Service and Technical Support

Quality consultation and after-sales services are strengthened to promptly address issues arising during installation, commissioning, and operation, ensuring the safe and stable operation of equipment.

II.Manufacturing Process Quality Control

1.Procurement Quality Control

Raw material quality forms the foundation of product quality. Major materials such as pipes, castings, and standard components are sourced exclusively from qualified suppliers with appropriate production qualifications and stable, reliable quality performance. Upon arrival, all materials are strictly inspected and accepted in accordance with relevant standards to ensure compliance with quality requirements.

2.Production Process Control

During manufacturing, key processes such as welding and assembly are subject to focused quality control. Process specifications and inspection requirements are strictly implemented to promptly identify and correct issues during production, continuously improving manufacturing quality and ensuring products meet design and operational requirements.

3.Final Product Inspection

Since its establishment, the company has set up a dedicated vacuum pump testing station and implemented an electronic inspection and data management system. All vacuum equipment must undergo standardized and comprehensive performance testing before delivery, with fully traceable inspection records generated for each unit. This ensures that every product is tested, traceable, and quality-controlled. Through rigorous final inspection procedures, the company effectively guarantees stable performance and reliable quality of delivered products, consistently meeting customer requirements.
