Pengyuejia Electrical Appliances: Full-process Closed-loop Quality Assurance System
Pengyuejia Electrical Appliances takes "precisely matching high-demand scenarios and creating reliable products" as its core quality goal. It has established a full-process closed-loop quality system covering "source - production - factory - after-sales", ensuring product quality meets the strict standards of various industries through comprehensive measures including systems, execution, supervision, and continuous optimization.
I. Strict Control at the Source: Raw Material Admission and Supplier Management
Quality control starts from the source.
The company has established a strict raw material access mechanism. For core raw materials such as cores, enameled wires, and insulating materials required for the production of transformers, common mode inductors and other products, clear quality standards and inspection norms have been formulated. Suppliers are required to provide authoritative quality inspection reports, and each batch of raw materials is subject to sampling inspection, including key indicators such as physical properties (such as insulation strength, temperature resistance) and electrical properties (such as conductivity, loss value), to prevent substandard raw materials from entering the production process. At the same time, suppliers are subject to hierarchical management. Through regular assessment of suppliers' production capacity, quality stability, and after-sales response speed, high-quality suppliers for long-term cooperation are selected, and strategic cooperative relationships are established to consolidate the quality foundation from the supply chain end.
II. Production Process: Standardized Procedures and Real-time Quality Monitoring
In the production process, the company strictly adheres to standardized operation procedures, embedding quality requirements into every step. For automated production equipment, it formulates regular calibration and maintenance plans to ensure the accuracy of equipment operation and prevent product quality from being affected by equipment errors. During production, key quality control points are set, such as the precision of coil winding turns, the firmness of welding, and the uniformity of varnishing. After each process is completed, it must pass double verification by self-inspection of the work team and inspection by the workshop to ensure that the process quality meets the standards. Especially for products adapted to high-precision scenarios such as aerospace, military, and medical fields, additional specialized process control measures are added. For example, in the production of common mode filters, high-precision detection equipment is introduced to monitor parameters such as inductance and impedance in real time, ensuring stable product performance and meeting the anti-interference and harsh environment resistance requirements of special scenarios.
III. Factory Inspection: Multi-dimensional and comprehensive testing to prevent substandard products from leaving the factory.
The company is equipped with a professional inspection team and complete testing equipment, and has established a "comprehensive inspection + special spot check" factory inspection mechanism. Before the finished products leave the factory, they must pass through three core inspection modules: basic performance inspection (such as the transformation ratio and no-load loss of transformers, inductance and DC resistance of inductors), safety performance inspection (such as insulation resistance and withstand voltage test), and environmental adaptability inspection (such as high and low temperature cycling and damp heat test), to ensure that the products meet the standards in terms of electrical performance, safety and stability. For special orders from military and medical sectors, additional special inspections such as vibration test and electromagnetic compatibility (EMC) test will be conducted according to customer requirements, and detailed inspection reports will be issued to ensure that the products fully comply with the special standards of the industry. Only when all inspection items are qualified can the products be labeled and leave the factory, and substandard products are resolutely prevented from entering the market.
IV. After-sales Traceability: Quick Response and Closed-loop Handling of Quality Issues
The company extends quality control to the after-sales stage and establishes a product quality traceability system. Each product is marked with a unique identification code, which can be traced back to production batches, raw material sources, inspection records and other information. Once a customer reports a quality issue, the after-sales team can respond within 24 hours, quickly locate the root cause of the problem (such as raw material batches, process deviations) through the traceability system, and promptly provide solutions (such as returns and exchanges, technical guidance). At the same time, the after-sales team regularly summarizes quality feedback data to form a quality issue analysis report, providing a basis for the optimization of front-end production and raw material control, and achieving a quality improvement closed loop of "after-sales - production - source".
