Dongguan Aotuo Precision Hardware Products Co., Ltd.

Our company is a professional manufacturer specializing in the development, production, and sales of metal clinching fasteners and precision hardware components.

Operating in strict accordance with the ISO 9001 Quality Management System, we focus on customer satisfaction and continuous improvement, providing stable and reliable fastening solutions.

In compliance with ISO 9001 requirements, our production processes are systematically managed with a well-organized production line layout. The main process flow includes:

Incoming Material Inspection → Cold Heading → Turning → Tapping / Slotting → CNC Precision Machining → Optical Sorting → Final Inspection & Packing

Quality control checkpoints are implemented at each stage to ensure full process control.

1. Cold Heading Machines: Cold heading machines are key equipment for forming fastener blanks, offering high efficiency and excellent dimensional consistency, especially suitable for mass production.
2. Lathe Machines: Lathe machines are used for machining outer profiles, end faces, and critical dimensions, suitable for prototype development and special-structure components.
3. CNC Lathes: CNC lathes are applied for high-precision and complex clinching fasteners, ensuring excellent dimensional accuracy and consistency.
4. Tapping Machines: Tapping machines are used for internal thread processing, ensuring thread accuracy and assembly performance in line with ISO 9001 critical characteristic controls.
5. Slotting Machines: Slotting machines are used for machining locating grooves and functional slots to meet diversified customer requirements.
6. Automatic Optical Sorting Machines: Optical sorting machines are applied for automatic inspection of appearance and dimensions, effectively reducing defect escape and supporting ISO 9001 quality assurance.

Our ISO 9001 Quality Management System is fully implemented through:

• Incoming material inspection and supplier control
• In-process quality control and inspections
• Focused control of critical processes and dimensions
• Final inspection and product traceability
• Nonconformance handling and continuous improvement

• Multi-process equipment configuration for mass production and customization
• Stable product quality and reliable delivery performance
