Suppliers

 

Hengfengyou Electric incorporates supplier quality management into its overall quality control process for power transmission and distribution equipment. For the manufacturing of transformers, switchgear, and other electrical equipment, we implement relevant supplier evaluations, quality performance monitoring, and procurement quality control measures for purchased materials, externally sourced components, and auxiliary parts.

Based on the technical requirements of different products and their intended project applications, we assess suppliers in terms of technical capabilities, product quality, specification compliance, and delivery performance. These efforts help align procurement requirements with product design, manufacturing processes, and project delivery needs, supporting product quality and supply chain stability.

 Supplier Evaluation and Continuous Management

A structured supplier evaluation and management process is an important part of procurement quality control. In accordance with relevant management procedures, Hengfengyou Electric evaluates and monitors suppliers based on their capabilities, supply quality, delivery performance, and problem-solving effectiveness, continuously improving supply chain management.

1.1 Supplier Qualification and Capability Assessment

Supplier assessments consider basic company information, technical capabilities, product quality, supply capacity, and relevant quality documentation. For new suppliers, initial delivery inspections or necessary trial-use verification may be arranged according to the product category, procurement requirements, and actual needs. These assessments provide a reference for subsequent procurement decisions.

1.2 Supply Quality and Delivery Monitoring

We monitor the quality, specification compliance, and delivery performance of purchased materials and externally sourced components. Ongoing assessments are conducted based on actual supply performance, while records and analyses of relevant issues provide a basis for supplier management and procurement decisions.

1.3 Quality Issues and Corrective Action Follow-Up

When quality issues arise with purchased materials or externally sourced components, investigations, immediate containment measures, and subsequent corrective actions are carried out in accordance with relevant management procedures. Depending on the nature of the issue and actual requirements, suppliers are encouraged to implement corrective measures, and the results are tracked to reduce the risk of recurrence.

1.4 Continuous Supplier Improvement

Supplier performance is reviewed based on product quality, delivery performance, and the effectiveness of issue resolution. Where suppliers fail to consistently meet applicable requirements, appropriate management measures are taken according to the evaluation results, supporting continuous improvement in supply chain quality and delivery management.

Major Procurement Materials and Electrical Components

Transformers, switchgear, and other power transmission and distribution equipment involve a variety of materials, electrical components, and auxiliary parts. Their performance, technical specifications, and suitability for specific applications can affect product design, manufacturing quality, and operational performance.

Hengfengyou Electric verifies the specifications and suitability of relevant materials and components against product technical documentation, procurement requirements, and project specifications, helping ensure that purchased resources meet product requirements.

2.1 Steel and Magnetic Materials

These materials mainly include transformer core materials, enclosure materials, and related structural components. During procurement, attention is given to material specifications, relevant performance indicators, processing quality, and batch consistency, providing a foundation for electrical performance and structural reliability.

2.2 High- and Low-Voltage Electrical Components

These include electrical components, control devices, and auxiliary equipment used in transformers and switchgear. Selection and specification verification are based on rated parameters, technical specifications, and project application requirements. Where customers specify particular brands or special configurations, component selection is coordinated in accordance with the requirements of the individual project.

2.3 Insulation Materials and Auxiliary Components

Insulation materials and related components are selected and verified according to the product voltage level, structural design, and operating conditions. Their specifications, performance requirements, and suitability are reviewed to ensure alignment with product design and applicable insulation system requirements.

2.4 Production and Testing Equipment Resources

Production equipment, process conditions, and testing equipment support material processing, product assembly, and quality inspection. Equipment maintenance, record management, and necessary personnel training help maintain stable production operations.

Supply Chain Quality Control and Procurement Management

Supplier quality management involves not only the performance of individual suppliers but also the coordination of procurement requirements, incoming material acceptance, and subsequent manufacturing processes.

Hengfengyou Electric manages relevant activities throughout procurement requirement confirmation, incoming material quality verification, nonconformity handling, and project procurement coordination. These efforts help ensure that purchased materials and externally sourced components meet applicable technical requirements.

3.1 Procurement Specifications and Technical Requirement Confirmation

Based on product drawings, technical documentation, procurement specifications, and project requirements, we confirm the technical parameters, specifications, and application conditions of relevant materials and electrical components. This helps reduce procurement discrepancies caused by inconsistent or incomplete information.

3.2 Incoming Material Inspection and Documentation Verification

In accordance with applicable inspection requirements, incoming materials and externally sourced components are checked for specifications, appearance, quality certificates, and relevant technical indicators to verify their compliance with the corresponding procurement requirements.

3.3 Quality Issue Handling and Feedback

Issues identified during incoming inspection or subsequent use are recorded and reported for further assessment. Where necessary, relevant parties coordinate the handling process. For issues requiring supplier corrective action, the implementation and results of corrective measures are tracked.

3.4 Project Procurement and Configuration Coordination

For projects involving different product models, technical parameters, customer-designated brands, and delivery requirements, we coordinate relevant procurement resources and component configurations to support manufacturing and project implementation.

Through supplier evaluation, procurement quality control, and quality issue follow-up, Hengfengyou Electric continues to improve supply chain management and strengthen coordination between procurement requirements, product quality control, manufacturing, and project delivery.
