In-line metal detector for plastics processing
Prevent costly breakdowns in plastics production with an in-line metal detector designed to efficiently remove contaminants from polymer melts, ensuring smooth operations and product integrity.
Detects and Removes Metal Contaminants
The PROTECTOR Series from Sesotec is designed to enhance the reliability of your plastics, rubber, and chemical processing lines by effectively detecting and removing metal contaminants. Installed directly before injection moulding machines, extruders, and blow moulding machines, it inspects slow-moving material columns, enabling the removal of both ferrous and non-ferrous metals. With two-channel detection coil technology, PROTECTOR provides high sensitivity, ensuring minimal material loss. It operates under continuous and high-speed conditions, making it ideal for applications in plastics recycling, electrical waste processing, and more. Featuring auto-learn functionality and the “Quick-Valve” separation unit, it offers easy operation and maintenance. This system is CSA and UL certified for North American markets, and its compact design allows for seamless integration with other machinery, ensuring minimal operational disruption and minimal downtime. Available materials withstand up to 140°C, providing durability in harsh environments, while optional magnet separators offer enhanced ferrous removal.
