Quality management methods
I. Purpose
In business operations, product quality is the foundation for a company to stand in the market. Ensuring product quality standardization and improving the quality level are crucial goals. Standardized product quality can enhance the company's credibility and strengthen consumers' trust, enabling the company to gain an advantageous position in the fierce market competition. Only by continuously improving the quality level can a company meet the ever-growing needs of consumers and lay a solid foundation for its sustainable development.
II. Scope
Quality management is involved from the research and development and design stages throughout the entire product lifecycle. Research and development is the source of product innovation, while design determines the basic structure and performance of the product. Only by strictly controlling quality in these two stages can reliable guarantees be provided for subsequent production and sales processes.
III. Design Quality and Management Workflow
The management operation process for design quality is the key to ensuring that product design meets quality requirements. It covers a series of steps from data collection, design, trial production to the final determination of standards.
IV. Implementing Unit
The Engineering Department, the Business Department, the Finished Product Section of the Quality Management Department and other relevant units jointly participate in the implementation. The Engineering Department is responsible for the design and development of products. The Business Department provides market information and customer needs. The Finished Product Section of the Quality Management Department supervises and inspects product quality. All units cooperate with each other to form an organic whole.
V. Implementation Points
1. Design stage: The Engineering Department needs to extensively collect materials on relevant domestic and international specifications such as CNS, JIS, and UL. At the same time, it should combine the materials such as market surveys, customer requirements, and customer complaint analyses provided by the Sales Department and the Quality Management Department. These materials are important bases for design, which can ensure that the designed products not only meet international standards but also satisfy the actual needs of the market and customers. When designing new products or improving existing products, these factors should be fully considered to enhance the competitiveness of the products.
2. Trial production stage: After the design is completed, trial production and inspection must be carried out. Trial production is an actual verification of the design scheme. Through trial production, potential problems in the production process can be discovered, as well as whether the product can meet the design quality requirements. If the trial production is unqualified, the design needs to be checked and revised, and then the trial production should be carried out again until it passes the test.
3. Standard formulation stage: After the trial production is qualified, a series of standards should be formulated in conjunction with relevant units, including material usage standards, material specifications, part specifications, product specifications, operation standards, standard working hours, and QC process sheets, etc. These standards serve as the basis in the production process and can ensure the stability and consistency of product quality.
4. Customer approval stage: If the newly designed product is ordered by the customer, the trial - produced qualified samples need to be submitted to the customer for approval by the sales department. Only after the customer's approval can the company start accepting orders, and the planning office will conduct production planning. This stage reflects the customer - centric concept and can ensure that the product meets the customer's expectations.
5. Data feedback and change stage: Engineering data should be promptly fed back to relevant units, and the design change operations such as specifications, standards, and blueprints should be strictly implemented. This can ensure that each unit can keep abreast of the latest design situation in a timely manner and avoid quality problems caused by untimely information.
VI. Implementation and Amendment of the Measures
These measures shall be implemented after being approved by the Quality Management Committee. The same approval process shall also be followed when making amendments. This ensures the seriousness and authority of the measures and guarantees the standardized implementation of quality management work.
Incoming material inspection regulations
I. Purpose
Ensure that the quality of incoming materials meets the standards and prevent non-conforming products from entering the production process. The quality of incoming materials directly affects the final quality of the products. Only by strictly controlling the quality of incoming materials can the stability of product quality be ensured.

IV. Implementing Unit
The Incoming Materials Section and Processed Products Section of the Quality Management Department, as well as other relevant units, are responsible for implementing incoming materials inspection work. These units should cooperate closely to ensure the accuracy and timeliness of the inspection work.
V. Implementation Points
1. Inspection stage: After receiving the acceptance form, the inspector shall conduct inspections strictly in accordance with the inspection standards, and accurately fill in information such as the supplier of the incoming materials, product name, specifications, quantity, and acceptance form number in the inspection record form. This is not only a record of the inspection work but also an important basis for subsequent traceability and management.
2. Judgment and processing stage: For the incoming materials judged to be qualified, mark them as "Qualified", fill in the inspection status in the inspection record form and the acceptance form, and notify the warehousing personnel to handle the warehousing procedures. For the incoming materials judged to be unqualified, mark them as "Unqualified", fill in the relevant records, and notify the purchasing department and the requisitioning department, and they shall decide whether to accept them on a special basis according to the actual situation. If special acceptance is not required, mark the incoming materials as "Return" and handle the return procedures; if special acceptance is required, conduct special acceptance processing according to the approval, and notify the relevant departments to handle the procedures such as warehousing, partial return, and deduction.
3. Time requirement: The incoming materials should be inspected within three days after receiving the inspection report. However, the incoming materials urgently needed should be processed with priority. This not only ensures the efficiency of the inspection work but also meets the urgent production needs.
4. Handling of special situations: If it is impossible to determine whether it is qualified or not during the inspection, the Engineering Department (Design Engineering Section) and the requisitioning unit should be requested to send personnel to conduct a joint acceptance inspection. Those participating in the joint acceptance inspection should sign and seal in the inspection record form to clarify their responsibilities.
5. Sampling requirements: When inspectors conduct inspections, sampling should be randomized. They cannot determine the acceptability based on personal feelings or subjective judgments. This can ensure the fairness and objectivity of the inspection results.
6. Information feedback and suggestions: The situation of incoming material inspection should be promptly fed back. The delivery quality of incoming material suppliers and the inspection and handling situation should be recorded in the Supplier Delivery Quality History Card, and summarized monthly in the Supplier Delivery Quality Monthly Report. Meanwhile, based on the inspection results, improvement suggestions or proposals for inspection specifications (materials, parts) should be put forward to continuously improve the quality of incoming materials.
7. Instrument management: Do a good job in the management and calibration of inspection instruments and gauges to ensure the accuracy of inspection results.
8. Handling of materials awaiting for OEM customers: For the incoming materials that OEM customers wait for on their own, when they are judged as unqualified, the sales department should be requested to contact the customers for handling.

Provisions on the implementation and amendment of the measures
In the entire product management system, this measure occupies a crucial position. It is an important criterion and specification for ensuring the orderly and efficient progress of various product - related tasks. Moreover, the implementation of this measure follows a strict and clear process.
When this set of measures is initially formulated, it will not take effect and be put into use immediately. Instead, it needs to be submitted to the Product Committee for comprehensive and meticulous verification. As a professional and authoritative organization, the members of the Product Committee have rich industry experience, profound professional knowledge, and keen market insight. They will evaluate this set of measures from multiple dimensions.
In terms of compliance, it will be checked whether the measures meet the requirements of relevant national laws and regulations and whether they are in line with the general norms and standards in the industry. At the level of rationality, an analysis will be conducted on whether each clause in the measures conforms to the actual situation of the product and whether it can effectively solve the problems that the product may encounter in various links such as R & D, production, and sales. At the same time, the operability of the measures will also be considered, and an assessment will be made on whether they are feasible in the actual implementation process and whether some clauses are too complicated or unrealistic, which may lead to difficulties in implementation.
Only when the Product Committee conducts a rigorous review and determines that this measure meets the requirements in all aspects will it approve the official implementation of this measure. At this time, this measure will serve as an important basis for product - related work and play a guiding and binding role within the entire organization.
In addition, during the implementation of this measure, due to factors such as the continuous changes in the market environment, the development of the product itself, and the adjustment of the company's strategy, it may be necessary to revise this measure. When a revision is needed, the revision process is the same as the process for the initial implementation of the measure.
Similarly, the revised content should be submitted to the Product Committee. The Committee will still conduct a strict review of the revised content, just as it did when approving the initial version. It is necessary to ensure that the revised measures can adapt to new situations and requirements without undermining the overall stability and coherence of the measures. Only after the approval of the Committee can the revised measures come into effect and be implemented officially. Such provisions ensure that these measures can always keep pace with the times and provide strong support and guarantee for the sound development of the products.
