Quality Certifications & Assurance: We adhere to stringent international quality standards and have obtained a full range of authoritative certifications to ensure product reliability. Our core certifications include ISO9001 Quality Management System Certification and ISO14001 Environmental Management System Certification. All our micro stepper motors, including customized products, fully comply with EU RoHS environmental protection requirements and have passed multiple international product certifications such as CE (Conformité Européenne) and UL (Underwriters Laboratories). To ensure consistent quality, we have established a comprehensive quality assurance system covering the entire lifecycle of products: from strict incoming inspection of raw materials (such as high-precision magnets and copper wires) to real-time monitoring of key production processes (including winding, assembly, and testing), and finally to 100% performance testing of finished products (covering step accuracy, noise, torque, and service life). This rigorous quality control system ensures that our product failure rate is maintained below 0.1%, providing a solid quality guarantee for long-term mutually beneficial cooperation with customers.
