The quality assurance system of Henan Hengxin Boiler Manufacturing Co., Ltd. is composed of various stages and links such as quality management, quality control, and product quality inspection. In the control program, a three-level responsibility system is implemented under the leadership of the general manager, consisting of quality assurance engineers, professional responsibility engineers, and professional technical personnel from various functional departments. They coordinate and cooperate with each other to operate reasonably. The comprehensive testing methods ensure strict quality assurance for every process. The quality assurance system includes multiple control systems such as design, process, material physics and chemistry, welding, flaw detection, inspection, equipment measurement, and production, forming a quality control system for the entire process from contract review to after-sales service. The quality verification principles, control systems, control links, control points, work basis, and witnessing of each system are specified, ensuring effective control of product quality. The procurement plan for raw materials in the production plan is formulated based on the technical parameters provided by the technical department. The business department conducts material procurement according to the plan. Before procurement, the supplier is first evaluated and selected, and the incoming materials are re inspected according to regulations. Unqualified materials shall not be stored or put into production. The three zones shall be clearly defined, and the distribution, collection, marking, transplantation, and substitution of materials shall be carried out in accordance with relevant regulations to ensure that the accounts, materials, and cards are consistent. The production process of the product involves strict process requirements for cutting, machining, product testing, welding, flaw detection, marking, drilling, assembly, hydrostatic testing, furnace laying, painting, packaging, and other processes. Through the control links, control points, and hold points of the inspection system, the control points are controlled, and any problems found during the hold points must be stopped. The "three no let go" system is implemented to ensure that the product manufacturing follows the "three press" and "three inspection" system, and quality issues are promptly reported. Non destructive testing shall be carried out based on the "commission form" of the surface inspection qualified workpiece. For the repair of defects exceeding the standard, the repair system shall be strictly implemented and retesting shall be carried out. In the various systems of the quality system, there are 34 control links, 55 control points, and 4 hold points. The key processes of each hold point and control point are in accordance with the system requirements, and various quality documents are clear and standardized. Approval and changes are made according to procedural regulations. Outsourcing and supply of external accessories shall be tested and implemented according to the system, and selected based on merit. The main pressure components shall be recorded on a one-to-one basis, with complete signatures and clear records for each process, achieving "two self controls" and "three satisfactions". On the basis of their respective qualifications, they shall consciously accept the supervision and inspection of the supervisory personnel, fulfill the procedures, and ensure that any non-conforming components are not transferred to the next process, so that product identification and traceability comply with the principle of uniqueness. At the same time, we will improve and perfect the sales service network, provide pre-sales, in sales, and after-sales services, track the sales of products, and promptly report quality issues to various functional departments through internal and external feedback channels. We will identify problems, formulate measures, summarize experience, and effectively solve customer concerns. The company adheres to the noble spirit of serving customers and becoming a century old enterprise. It has established a product pre-sales consultation and after-sales service system, with a complete quality assurance file, to quickly solve practical problems such as product installation, use, and maintenance, and provide customers with stable and reliable technical support.
