The Openex Fastener Inspection Machine is a high-speed AI vision inspection system designed for automatic quality control of screws, bolts, nuts, studs, and other precision fasteners.
Using multi-camera optical inspection and deep-learning defect detection, the system can inspect surface defects, dimensional errors, thread damage, and head defects at speeds up to 1200 pieces per minute.
This enables fastener manufacturers to achieve 100% automated inspection, reduce labor costs, and ensure consistent product quality before shipment.
Why Fastener Inspection Is Critical
Fasteners are used in automotive, aerospace, electronics, and machinery, where even a small defect can cause major failures.
Common quality problems include:
- Thread damage
- Head cracks
- Burrs or flash
- Missing threads
- Dimensional deviations
- Surface scratches
- Plating defects
Traditional manual inspection is slow and inconsistent. The Openex AI vision system ensures reliable, repeatable inspection at industrial production speeds.
