I. Purpose: Quality planning for forgings is a crucial element in ensuring stable quality throughout the forging production process and meeting customer requirements. It involves the entire process from raw material procurement to product delivery, and through systematic planning and control, it aims to prevent quality issues and improve the quality rate and reliability of products. II. Quality Planning Objectives 1. Define the quality requirements and standards for forgings to ensure compliance with customer expectations and relevant industry regulations. 2. Establish an effective quality management system that covers the entire production process in order to achieve comprehensive monitoring and control of quality. 3. Improve the first-pass yield in forging production, reduce the scrap rate and rework rate, thereby enhancing production efficiency and economic benefits. 4. Continuously improve the quality planning process, and constantly optimize the quality management system and production processes to adapt to market changes and the increasing demands of customers. III. Contents of Quality Planning (I) Quality planning during the product design and development phase 1. Conduct thorough communication with the customer to obtain key information such as the operating environment of the forgings, performance requirements, and dimensional accuracy, and transform this information into detailed design inputs. 2. Organize cross-departmental teams (including departments such as design, engineering, and quality) to conduct design reviews, assess the feasibility and rationality of the design solutions, and ensure that the design meets quality requirements and is easy to manufacture. 3. Develop a product development plan that specifies the tasks, deadlines, and responsible persons for each stage, to ensure that the design and development work progresses in an orderly manner on schedule. 4. During the design process, tools such as Failure Mode and Effects Analysis (FMEA) should be utilized to predict and evaluate potential design flaws and quality issues, and to formulate corresponding preventive measures. (II) Quality planning during the raw material procurement stage: 1. Establish strict standards for raw material procurement, specifying requirements regarding the specifications, models, and quality grades of such materials, to ensure that the purchased raw materials meet the quality requirements for forging production. 2. Evaluate and select suppliers, and establish a list of qualified suppliers. The evaluation covers aspects such as the supplier’s production capacity, quality assurance system, and historical product quality, with the aim of selecting suppliers with reliable quality and a good reputation for cooperation. 3. Sign a quality agreement with suppliers to clarify the quality responsibilities and obligations of both parties, including the quality acceptance criteria for raw materials and the procedures for handling non-conforming products. 4. Establish an inspection system for incoming raw materials. Each batch of raw materials must be inspected; the inspection items include chemical composition, physical properties, and appearance quality, etc. Only when the raw materials meet the quality standards can they be used in production. (III) Quality planning during the production process 1. Develop detailed production procedure documents, including forging procedures, heat treatment procedures, machining procedures, etc., specifying the operation methods, process parameters, and key quality control points for each step, to ensure the standardization of the production process. 2. Carry out maintenance and upkeep of production equipment, establish operating procedures and maintenance plans for the equipment, and conduct regular inspections, repairs, and calibrations to ensure its proper operation and meet accuracy requirements, thereby guaranteeing the stability of the production process and the consistency of product quality. 3. Establish key quality control points to closely monitor the critical processes and parameters that affect the quality of forgings. For example, parameters such as the starting and final forging temperatures and the degree of deformation during the forging process, as well as the heating temperature, holding time, and cooling rate during heat treatment—these are all monitored and recorded in real time. This enables timely detection and correction of any deviations, thereby ensuring that the product quality meets the required standards. 4. Conduct employee training to improve their operational skills and quality awareness. The training content includes process operation procedures, quality control methods, and safety production knowledge, ensuring that employees can master the production processes and quality requirements proficiently and carry out production in strict accordance with the operating procedures. 5. Implement self-inspection, mutual inspection, and specialized inspection systems during the production process to strengthen quality control at each stage. Operators conduct self-inspections on the products they process during production, while the subsequent processing stages carry out mutual inspections of the products from the previous stage. Quality inspectors perform specialized checks, and through these multiple levels of inspection, defective products are identified and removed in a timely manner, preventing them from reaching the next stage of production. (IV) Quality planning during the quality inspection and testing phase: 1. Develop a comprehensive quality inspection plan that specifies the inspection items, methods, frequency, and sampling procedures, to ensure thorough and accurate inspection and testing of the quality of the forgings. 2. Equip with necessary inspection and testing equipment, such as chemical composition analyzers, mechanical property testing machines, metallographic microscopes, and dimension measurement tools, and regularly calibrate and maintain these devices to ensure their accuracy and reliability. 3. Strict inspection and testing are carried out on raw materials, semi-finished products, and finished products; the inspection includes aspects such as appearance quality, dimensional accuracy, chemical composition, mechanical properties, and metallographic structure. For non-conforming products, they are labeled, isolated, reviewed, and handled in accordance with the non-conforming product control procedures to prevent their unintended use. 4. Conduct quality statistical analysis by collecting, organizing, and analyzing inspection and testing data. Utilize statistical tools such as control charts and histograms to identify patterns and trends in quality fluctuations, and take timely actions for adjustments and improvements to ensure the stability of product quality. (5) Quality planning during the packaging, storage, and delivery stages: 1. Develop a reasonable product packaging plan; based on the characteristics of the forgings and the requirements for transportation, select appropriate packaging materials and methods to ensure that the products are not damaged during transport and storage. 2. Establish a standardized product storage management system, designate dedicated storage areas, classify products for storage, and implement protective measures such as moisture prevention, rust prevention, and impact protection to ensure the quality of product storage. 3. Before product delivery, conduct another inspection to ensure that the delivered products meet quality standards. At the same time, prepare the relevant quality certification documents (such as inspection reports, material certificates, etc.) and deliver them to the customer along with the product. 4. Establish a customer feedback handling mechanism to promptly collect customers’ opinions and suggestions on product quality, address and improve the quality issues identified through such feedback, thereby enhancing customer satisfaction. IV. Implementation of Quality Planning 1. Establish a quality planning implementation team, define the responsibilities and roles of team members, to ensure the smooth progress of quality planning activities. 2. In accordance with the contents and requirements of the quality planning, develop a detailed implementation plan, assign various tasks to specific departments and responsible persons, and define the time schedules. 3. During implementation, strengthen communication and coordination to address any issues and difficulties that arise promptly. Regularly hold meetings on the implementation of quality planning, summarize and evaluate the implementation status, and promptly adjust the implementation plan and measures to ensure the achievement of quality planning objectives. 4. Establish a supervision and evaluation mechanism for the implementation of quality planning, to monitor and assess the progress of work and the quality of outcomes achieved by various departments and responsible persons. Link the evaluation results to performance incentives in order to motivate employees to actively participate in the implementation of quality planning. V. Evaluation and Improvement of Quality Planning 1. Regularly evaluate the effectiveness of quality planning implementation, with the evaluation covering aspects such as the achievement of product quality indicators, the effectiveness of the quality management system, and customer satisfaction. 2. Based on the evaluation results, analyze the problems and shortcomings in the quality planning process, identify the causes, and formulate improvement measures. 3. Track and verify the effectiveness of the improvement measures to ensure that problems are effectively resolved and the level of quality planning continues to improve. 4. Integrate the results of quality planning evaluation and improvement into the quality management system to establish a mechanism for continuous improvement, thereby continuously optimizing the quality planning process and the quality management system, and enhancing the quality of forgings as well as the company’s market competitiveness.
