Quality
Jewelry production focuses on quality, ensuring each piece is crafted with precision and beauty.
Quality Control Process
It ensures products meet high standards through careful checks at every stage.
Raw Material Control
Supplier Evaluation
Establish a strict supplier evaluation system to comprehensively assess suppliers' qualifications, credibility, production capacity, quality control systems, etc., giving priority to suppliers with good credibility and stable quality.
Raw Material Inspection
Conduct rigorous inspections on purchased raw materials, such as diamonds, gemstones, metals, etc. Inspection items include appearance, weight, purity, color, clarity, etc. For critical raw materials, advanced detection equipment and technologies, such as X-ray fluorescence spectrometers and spectrophotometers, should be used.
production process control
Review of Jewelry Design Plans
Conduct a review of the design plans for jewelry products to ensure they meet relevant standards and customer requirements. The review covers structural rationality, process feasibility, aesthetic appearance, and other aspects.
Standardization of Production Processes
Develop detailed production process flows and work instructions, clarifying the operational norms and quality requirements for each process step. Focus on monitoring key processes such as setting, grinding, and polishing.
Inspection of Semi-Finished Products
During production, conduct regular inspections of semi-finished products to promptly identify and rectify quality issues. Inspection items include dimensions, shape, surface quality, and the firmness of settings.
Finished Product Inspection
Physical Property Testing
Test the physical properties of jewelry products, such as hardness, density, and refractive index. For precious metal jewelry, test its purity and content.
Appearance Inspection
Inspect the appearance of jewelry products, including overall design, surface finish, scratches, flaws, etc., to ensure that the product appearance meets design requirements and relevant standards.
Gemstone Identification
Identify gemstones to determine their species, origin, color, clarity, and other characteristics. Use professional equipment such as microscopes, refractometers, and spectroscopes for identification.
Equipment and Personnel
Equipment Procurement and Maintenance
Reasonably procure advanced and accurate detection equipment based on testing needs. Regularly calibrate and maintain detection equipment to ensure its accuracy and reliability. Establish equipment calibration and maintenance records archives.
Personnel Training
Provide equipment operation training for testing personnel to enable them to proficiently master the usage methods and precautions of the equipment. Testing personnel should possess relevant professional knowledge and skills, have undergone training, and obtained corresponding qualification certificates. Regularly organize training and assessments for testing personnel to continuously improve their professional competence. Training content includes detection techniques, standard regulations, quality management, etc.
Specification
Specification: Detailed guidelines ensuring product quality, consistency & performance.
Prevention-Oriented Approach
Rigorous control over raw materials, production processes, and equipment to prevent quality issues from arising.
Full Process Control
Quality control should permeate the entire process of jewelry product design, material procurement, production and processing, and finished product inspection.
Continuous Improvement
Continuously summarize the experiences and lessons learned from the quality control process, continuously optimize quality control procedures and methods, and improve product quality.
Quality Records
Establish a comprehensive quality record system to record quality data for raw material procurement, production processes, and finished product testing. Quality records should be true, accurate, complete, and clear. Classify, archive, and store quality records to establish quality archives. Quality archives should be kept for a certain period for easy retrieval and traceability.
Disposition of Nonconforming Products
Clearly define criteria and procedures for identifying nonconforming products. Identify and isolate nonconforming products detected during testing. Based on the specific circumstances of nonconforming products, take measures such as rework, scrap, or downgrade. Record the disposition process of nonconforming products. Analyze the causes of nonconforming products and take corresponding corrective and preventive measures to prevent similar issues from recurring.
Internal Quality Supervision
Establish an internal quality supervision mechanism to regularly supervise and inspect quality control and testing work. Promptly rectify any issues identified.
Third-party certification
Verifying quality, credibility, & compliance by independent experts.
