A sound quality management system

1 Overview and System

Huaihua Jiannan Machinery Factory Co., Ltd., as a former electronic military enterprise, has always regarded "craftsmanship spirit" and "military quality" as the foundation of the enterprise's survival. It has put forward the quality policy of "using technology to promote enterprise development and surpassing customer expectations with quality".

The company conducts comprehensive quality control from product research and development design, material procurement, product manufacturing, production process, product monitoring process, etc. Passed GB/T 19001:2016/ISO9001:2015 quality management system certification and GB/T24001-2016/ISO14001:2015 environmental management system certification. Introduced the Yonyou ERP management system to effectively control materials and prevent cost waste. To ensure effective control of the entire product production process, our company has independently developed a production management system. Each product must go through the necessary processes and procedures before it can proceed to the next stage. Skipping the production system will result in an error message, which can trace the flow of each product and ensure quality control.

To effectively supervise and implement the quality management system to ensure product quality, the company has established a Quality Management Department; We have established QE group, QA group, and QC group respectively.

The Quality Management Department has 62 members, including 2 master's students, 5 undergraduate students, and the rest with high school or above cultural qualifications.

A sound quality control process is necessary to ensure product quality and meet customer requirements.

Quality Control Process

Design and Development Quality Management Process

In order to fully implement the company's quality policy of "using technology to promote enterprise development and exceeding customer expectations with quality", the company has been involved in quality from the design and development stage, tracking and analyzing the quality of each stage of design and development, implementing APQP (Advanced Product Quality Planning) and FMEA (Failure Mode and Effects Analysis) tools, effectively preventing product design defects, controlling potential quality hazards that may exist in the design and development process, and improving product reliability. At the same time, the company has introduced a large number of experimental equipment to strengthen product reliability testing and verification work, conducting reliability testing and verification on components and complete products, so that the design life of the products exceeds the life requirements specified by State Grid products.

2 Supplier selection process

To ensure the qualifications and supply capabilities of our suppliers, our company follows the principle of "inquiry, comparison, and negotiation" in the selection of all raw material suppliers. Under the same price conditions, suppliers with strong quality capabilities are given priority. We conduct on-site inspections and evaluations of various material suppliers, and give priority to suppliers with significant performance in the industry to avoid quality losses caused by suppliers who do not have the strength to supply. At the same time, strict testing must be conducted on the supplier samples before they can be selected for our company's supplier list.

3. Procurement Control Process for Incoming Materials

The company has a comprehensive and reliable material quality control system, with material quality imported by suppliers, material certification, material batch supply control, and supplier quality assurance. To ensure that the quality of raw materials supplied by suppliers meets our company's quality control requirements, we have formulated the "Raw Material Inspection Specification" and "Inspection Operation Manual" to strengthen control. Strict testing is conducted on samples and materials provided by various suppliers, and sample quality is an important assessment indicator for our company's supplier admission.

4 Production Quality Control Process

In order to implement the various process requirements in our company's production process, we have implemented strict quality control for each process of the production process, focusing on key processes to ensure that all quality in the production process can be effectively controlled. Our company requires IPQC to conduct online verification on all online materials, confirming that the specifications, names, and quantities of the online materials are correct before proceeding with first piece production, in order to avoid material misuse and omission from the source. The responsible department for any quality abnormalities that occur during the process must submit a corresponding 5D improvement report and confirm the effectiveness of the measures by the quality management department before continuing with production to ensure that there are no batch quality accidents.

5. Incoming Quality Inspection Process

In order to effectively control the materials provided by various suppliers to meet our company's quality requirements, our company inspects all raw materials according to the inspection specifications and inspection guidelines in accordance with GB/T2828.1-2012 standard. We return materials that do not meet our company's quality requirements and urge suppliers to respond with effective corrective and preventive measures. We verify the effectiveness of the measures in the next batch of incoming materials and provide regular quality guidance to suppliers to improve their quality control capabilities and avoid quality problems with raw materials from the source. When non-conforming materials are found during the batch inspection process, the Quality Management Department will reject them according to the acceptance criteria, and provide feedback to the raw material supplier through QE for improvement. The supplier is required to submit an 8D report within a specified period of time and verify the effectiveness of the response measures for the next batch of incoming materials, forming a closed loop.

6 Process Quality Exception Handling Process

To effectively control potential quality risks in the production process, our company has implemented defect control measures for each process. We have implemented quality anomaly feedback and shutdown mechanisms for processes that exceed the number of defects to avoid batch quality accidents. When the quality abnormality exceeds the control target, the abnormal workstation shall report it layer by layer according to the quality stop line management system requirements. The engineering service department and quality management department must arrive at the site within 10 minutes to handle it, and provide temporary measures within 30 minutes to reduce the loss of production abnormal working hours. Afterwards, the corresponding abnormal loss of working hours will be counted and the responsible department will be punished accordingly.

7 Factory Quality Exception Handling Process

To ensure that all products shipped by our company meet customer requirements, we conduct both full inspection and OQC sampling on all finished products. We analyze any abnormalities found during the factory inspection and require corresponding rectification of the batch of products before OQC sampling. Only after passing the inspection can the products be shipped to ensure their quality. Any performance quality abnormalities found during the factory sampling process are not allowed to be shipped.

8. After sales quality complaint handling process

In order to quickly respond to customer quality complaints, our company has established a quality handling team after receiving customer complaint information. We analyze the customer complaint information and identify the real cause of the problem. Within 2 hours, we will reply to the customer with the corresponding handling method and internally confirm the corresponding replenishment or repair processing time. The product will be returned to the customer in the shortest possible time.
