Product Quality Management System
Quality Management Structure and Processes

The Company has established a full-lifecycle product quality management process based on production procedures. Taking the Penglai Facility as an example, after receiving the technical drawings, the Technical Department will conduct a detailed breakdown of the drawing requirements, output a material procurement list and provide construction drawings for the production workshop to carry out construction procedures. The construction drawings include quality control points that enable a more efficient quality management and control during the production process. Each production workshop will carry out, implement, and inspect the production quality of each assembling step according to the production plan. The Warehouse Department of the Facility controls the quality of materials during storage. To achieve this, it has developed management provisions, such as the Storage Region Distribution and Protection for Materials in Storage Centre and theWarehouse Management Control Procedure, clarifying the requirements for logistics support and the feedback mechanism for quality issues to ensure the quality of raw materials.

Penglai Facility has set up the Quality Management Department, which is composed of Quality Assurance (QA), Quality Control (QC) and Non-destructive Testing (NDT) sections working together to supervise, manage, and control the quality of all production processes. Their collective efforts aim to ensure that products meet customers’ quality requirements.

Quality Risk Management

To effectively identify, detect, and prevent quality risks, the Penglai Facility has applied three major quality management tools and principles (8D, 5WHY, and PFMEA) in a coordinated manner so to plan and ensure the control of quality. After analysing the failure modes of early-stage risks, risk management and control measures are input into the quality control plan to establish a quality management plan, ensuring efficient quality management throughout the entire production process. For potential quality-related issues that are identified, we use quality management tools to conduct analysis and investigation, and develop specific quality control plans as the basis for product quality inspection. Regular quality inspections are also conducted during the production process according to the quality control plans. In case of quality-related issues, the Company will require relevant departments to take the following measures to avoid the recurrence of such issues: conducting on-site analysis, formulating and implementing solutions immediately, developing a prevention plan after these quality issues are properly addressed, summarising the lessons learnt, and recording them in the quality repository.

The Company has established the Change Management Control Procedure to standardise the process when technological deviations occur prior to product production. In such cases, the facility needs to conduct technical clarification with customers in accordance with the control procedure, discuss in detail with customers the extent of the impact of the technological deviation on quality and potential solutions, and then make adjustments to the technological process and split the process flow according to the agreed-upon plan. The adjusted plan is then issued to the production department for implementation to ensure that the product quality meets customer requirements. We will rework, repair, or scrap non-conforming products in a timely manner depending on the severity of quality issues. In addition, the Company has formulated the Non-conforming Product Control Procedure, specifying that inferior products and defective products shall be reworked, repaired, or scrapped depending on the severity of the quality issues.

Production Quality Objectives

The Company sets annual quality management targets in key procedures, such as technical processes, production capabilities, product types, and calibration of quality measurement instruments. At the same time, each facility conducts monthly monitoring, statistics, and analysis of the target qualification rate, takes corrective measures for any substandard situations, and thoroughly analyses and summarises all quality issues to prevent similar problems from recurring.
