How does your factory ensure the quality of nylon retainers?

We implement a rigorous end-to-end quality control system:Raw Material Management: Utilizing high-quality nylon raw materials from BASF with stringent incoming inspection. Process Monitoring: Real-time monitoring of critical process parameters (temperature, pressure, time) during production.Comprehensive Inspection: Multiple inspection procedures are executed, including but not limited to: visual inspection, full inspection/sampling of critical dimensions (using precision measuring instruments such as coordinate measuring machines and projectors), and functional testing (e.g., assembly testing). Quality Certification: We continuously strive to enhance our quality management standards, comply with relevant industry standards (such as ISO 9001), and provide inspection reports upon customer request.
