Metal Detector Used in Plastic Recycling Production Line
Industry: Plastic Recycling | Location: Vietnam
Customer Challenge
A plastic recycling factory in Ho Chi Minh City was facing frequent production line shutdowns due to metal contamination in recycled plastic pellets. Metal fragments — including nails, screws, wire and steel pieces — were regularly damaging extruder screws, causing quality rejects and costing thousands of dollars in downtime and repairs.
The factory needed a reliable metal detection solution that could:
• Handle high-volume recycled plastic pellets
• Detect all metal types (Fe, Non-Fe, SUS)
• Integrate with their existing conveyor line
• Automatically reject contaminated product without stopping the line
DORIA Solution
DORIA installed a custom conveyor metal detector with 500mm channel width, integrated directly into their existing production line. The system features:
• Multi-frequency detection technology for maximum sensitivity
• Automatic rejection system (pneumatic pusher)
• Real-time monitoring and data logging
• IP65 waterproof rating for industrial environments
• Easy-to-use touch screen interface
• Tool-free belt removal for cleaning and maintenance
Results & Benefits
After 6 months of operation, the factory reported:
• 95% reduction in metal-related production downtime
• $20,000/month savings in equipment repair costs
• Zero metal contamination findings in ISO 9001 quality audit
• Payback period: less than 3 months
• Improved product quality and customer satisfaction
• Reduced labor cost for manual inspection
Customer Feedback
"The DORIA metal detector paid for itself in less than 3 months. We used to have weekly shutdowns due to metal damage, now it's almost zero. The automatic rejection system works flawlessly and the touch screen is very easy to operate."
