Award-Winning Quality: Why Goodkey is Ranked Among the Top 10 Suppliers for High-Precision Stamping

As an ISO9001-certified enterprise, we go beyond standard system processes. Goodkey focuses on three critical technical pillars to ensure every component meets the rigorous demands of global industrial leaders.

1. Engineering Expertise & Staff Stability

Consistency in precision manufacturing starts with experienced people. Our production team is exceptionally stable; as of 2026, our minimum working tenure is 7 years, while our senior technical staff exceeds 22 years of service. This deep institutional knowledge ensures that every complex touch spring is manufactured with expert precision.

2. Automation & Equipment Innovation

We believe automation is the only path to absolute quality consistency. We continuously invest in proprietary automated machinery to eliminate human error and enhance production efficiency.

Case in Point:

• Stamping Monitoring: Automatic alarm and stop devices that monitor for any process abnormalities in real-time.
• Precision Assembly: Custom-built automatic riveting machines designed for seamless connection between metal plates and compression springs.

Our automated riveting line handles over 200,000 pieces daily with flawless precision.

3. Advanced Automated Optical Inspection (AOI)

To guarantee zero-defect manufacturing, we have deployed two sets of self-developed online dimensional monitoring systems. Every single capacitive touch spring undergoes 100% visual inspection.

Our AOI systems monitor critical positional tolerances that standard testing might miss, including parallelism, perpendicularity, and concentricity.

Technical Capabilities:

• Real-time online detection of spring dimensions, flatness, and perpendicularity.
• Automated dimensional measurement for high-precision SMT metal stamping parts.

Self-developed AOI machines ensuring 100% dimensional accuracy for industrial applications.

Advanced AOI Application Examples

Precision is maintained through our self-developed Automated Optical Inspection (AOI) technology, ensuring zero-defect delivery for complex components:

• Capacitive Touch Spring Detection: Real-time online monitoring of critical dimensions, including flatness, perpendicularity, and other essential positional tolerances.
• SMT Metal Stamping Parts: An integrated AOI system designed for high-speed, real-time dimensional measurement to guarantee consistency across mass production runs.
