METAL DETECTION FOR MATERIAL COLUMNS
Precise Metal Detection for Ultimate Material Purity
Even the smallest metal particles in plastic melt can cause costly disruptions in injection molding, extrusion, and blow molding. The risk increases with the growing use of regrind and recycled materials in the plastics processing and recycling industries. PROTECTOR metal separators remove metallic contaminants directly at the material feed above the machine – safely and reliably.
Who Benefits from Metal Detectors for Material Columns?
Metal detectors are strategically placed right before injection molding machines, extruders, and blow molding machines to inspect slow-moving or stationary material columns. They efficiently remove all magnetic and non-magnetic metals, even those embedded within the product, with minimal loss of good material.
Primarily for the plastics industry, especially for manufacturers and processors using granulate, regrind, or recyclate in injection molding, extrusion, or blow molding processes.
Magnets only remove ferromagnetic metals, while metal detectors can also identify and eliminate non-magnetic metals like stainless steel, aluminum, or brass. This ensures more comprehensive protection against contamination.

- Non-Ferrous Metals
Common iron foreign bodies include machine parts, screws, nails, wires, or wear from conveyor belts and production equipment.
Plastic products can sometimes contain production residues like shavings, screws, or broken tools from mechanical processing.
Stainless steel often enters production through worn or damaged machine parts, pipelines, or cutting tools.
Aluminum, copper, or brass often come from packaging materials, cable scraps, pipelines, or machine wear parts.
