Quality control measures in our company are integral to ensuring that products and services consistently meet predefined quality standards, from raw material sourcing to final delivery. Below are quality control approaches:
Quality Management System (QMS)
• Implementing international standards such as ISO 9001 to ensure systematic methods for managing and continually improving quality.
Raw Material and Supplier Management
• Evaluating and selecting suppliers to guarantee the provision of materials that comply with quality standards. • Inspecting raw materials before admission to prevent substandard materials from entering production.
Production Process Control
• Employing Statistical Process Control (SPC) to monitor key parameters in production processes, preventing quality issues. • Conducting first article inspection to ensure initial products meet equirements. • Performing in-process inspections and quality checks to maintain product quality during production.
Product Inspection and Release Management
• Final product inspection to ensure all quality standards are met prior to shipment.
• Executing final inspection, allowing only qualified products to be released for sale.
Continuous Improvement and Customer Feedback Handling
• Collecting customer feedback for product and service enhancement. • Utilizing the PDCA (Plan-Do-Check-Act) cycle to sustainably improve the quality management system.
Quality Control Tools
• Applying the Seven Basic Tools of Quality (Characteristic factor diagram, Pareto chart, checklist, stratification method, scatter plot, control chart) for data analysis and problem-solving. • Adopting Six Sigma and Lean methodologies to reduce waste and defects.
Quality Management System Certification and Training
• Providing quality awareness and skill training to employees to ensure everyone understands the importance of quality control.
• Acquiring external certifications such as ISO 9001 to bolster company credibility.
Quality Accountability
• Defining clear quality responsibilities for all levels of staff to ensure ndividual accountability for work quality. • Establishing a quality performance evaluation mechanism linking quality performance to personal performance metrics.
Internal Audit and Management Review
• Conducting regular internal audits to verify the effectiveness of the quality management system. • Management reviews led by senior management to ensure that quality policies and objectives are aligned with company strategy.
Communication and Collaboration
• Strengthen cross-departmental communication to ensure that all teams are involved in the quality control process. • Maintain good communication with suppliers, customers and third-party inspection agencies to ensure accurate transmission of information
Quality Management System
A management system is a formalized, systematic framework that guides an organization to achieve its strategic goals, continuously improve performance, and ensure compliance with relevant laws, regulations, and standards. An effective management system typically covers the following key aspects:
Goal setting
Clarify the organization's long-term and short-term goals and ensure that all activities work towards these goals.
Planning and strategy
Develop specific plans and strategies to achieve goals. This includes resource allocation, risk assessment, and planning of response measures.
Process control
Establish and maintain a series of standard operating procedures (SOPs) to ensure consistency and predictability in daily work. This involves monitoring and controlling processes to ensure that they operate as planned.
Performance monitoring
Regularly evaluate the organization's performance, use key performance indicators (KPIs) to measure progress, and identify areas for improvement.
Continuous improvement
Use methods such as the PDCA (Plan-Do-Check-Act) cycle to continuously look for improvement opportunities, optimize processes, and improve efficiency and effectiveness.
Risk management
Identify, assess, and control potential risks to prevent adverse events from occurring or mitigate their impact.
Compliance
Ensure that the organization's operations comply with all applicable laws, regulations, industry standards and codes of ethics.
Personnel and resource management
Rationally allocate human resources and other necessary resources, provide necessary training and support, and ensure that employees have the capabilities required to perform their duties.
Communication and collaboration
Establish effective communication channels to ensure that information flows smoothly within the organization and with external stakeholders. Promote team collaboration and enhance organizational cohesion.
Leadership and culture
Senior leaders should actively participate in and support the management system, shape a positive corporate culture, and encourage open communication and innovative thinking.
Customer and stakeholder satisfaction
Pay attention to the expectations and feedback of customers and other stakeholders, and ensure that products and services can meet or even exceed their needs.
Environmental and social responsibility
Consider the organization's impact on the environment, implement sustainable practices, and fulfill social responsibilities to promote the well-being of society and the environment.
Information technology application
Use information technology and data analysis tools to improve management efficiency, support decision-making, and achieve intelligent management.
Certification and audit
Conduct internal and external audits regularly, and obtain third-party certification, such as ISO series standard certification, to verify the effectiveness and compliance of the management system.
Diamond Saw Blade Production Process Quality Control Standards
Material preparation
The saw blade blank needs to be checked with a caliper to check the flatness of the saw blade end surface. The size of the diamond segment is strictly regulated, and the thickness is at least 0.8mm greater than the thickness of the saw blade blank.
Welding
Check the number of diamond segment and whether the specifications match the saw blade blank. Check whether the silver solder sheet meets the standard of the welding saw blade grade. The welding burn mark shall not exceed the bottom of the sink. The welding copper tube should be placed at 1/3 of the diamond segment and 2/3 of the saw blade blank. The highest welding temperature should not cause the diamond segment to bubble or deform, and ensure that the silver solder sheet is completely melted.
Welding inspection
The quality inspector checks whether there is a welding gap in the diamond segment and whether the silver solder sheet overflows between the diamond segment and the saw blade blank. Check whether the welding marks pass the sink. Check the flatness of the welded diamond segment, ensure that both sides are higher than the thickness of the saw blade blank, pick out the unevenness, and mark it. Use the corresponding standards to test the welding strength.
Surface treatment
Make sure the saw blade is painted or polished. 100% remove welding marks and uneven surfaces at welding points. If it is a painted product, polish to remove surface impurities. If it is a polished surface, strictly polish the surface to ensure smoothness and integrity.
Detection of surface treatment
Check whether the surface is clean. The painted surface is required to be flat and free of impurities.
Sharpening
Ensure that the front, back and cutting surfaces of the diamond segment reach the sharpening value 100%. For a small number of unsharpened saw blades, use a grinding wheel to process and sharpen.
Detection of sharpening
Check whether the sharpening is complete.
Surface treatment and packaging
Determine matters such as printing trademarks. Spray dry oil (painted products/spray diamond segment). Pay attention to waterproof packaging, and pay attention to the shipping area, channel and whether the packaging be damaged during transportation.
