Optical Sorting Success: Resistorx® Screws Inspected in 72 Hour

Optical Sorting Case Study

Resistorx® Screw – 100,000 Parts Delivered in 72 Hours

The Challenge

A customer urgently air-freighted 240,000 Resistorx® screws in bulk from Italy, requiring immediate verification prior to production use.

During receipt, there were suspected cracked heads, creating a critical quality concern. These components required 100% optical inspection to identify and remove any defective parts before release.

The customer required 100,000 fully inspected, verified, and approved parts within an extremely tight timeframe, with no compromise on quality.

Nufast’s Custom Optical Sorting Response

Nufast mobilised immediately to ensure rapid inspection and delivery.

Preparation and planning began before the shipment arrived:

• Optical sorting equipment prepared and programmed in advance
• Inspection criteria configured specifically for cracked head detection
• Sorting parameters validated for Resistorx® geometry and head profile

Digital Inspection Execution timeline:

• Fasteners received late Monday afternoon
• Optical sorting commenced immediately
• Continuous high-speed inspection using precision optical detection systems
• Defective components automatically rejected
• Approved components verified and packed to customer specification
• 100,000 fully inspected parts completed by Thursday morning

All approved components were carefully packed in 500-piece quantities per bag, ensuring ease of handling and traceability.

The Result

From arrival to dispatch, the complete process was achieved in under 72 hours.

The customer received 100,000 fully verified, production-ready components, enabling their operations to continue without interruption.
