From raw material handling and compounding to extrusion, molding, and recycling, plastic and rubber production lines face continuous contamination risks. Metal contaminants introduced from raw materials, processing equipment, and recycling streams can damage expensive machinery, reduce material quality, and increase production downtime. Understanding these risks is the first step toward building an effective metal separation and inspection strategy for more reliable manufacturing.
Metal contaminants from raw materials, shredders, grinders, extruders, and processing equipment can enter plastic and rubber materials during production. Ferrous, stainless steel, copper, aluminum, and other metal particles may damage downstream equipment, affect product quality, and increase maintenance costs.
Raw materials, recycled plastics, rubber compounds, and additives may contain metal impurities introduced during transportation, storage, or recycling processes. Removing these contaminants before processing helps protect equipment and improve final product consistency.
Continuous operation of crushers, mixers, extruders, and injection molding equipment can cause component wear over time. Loose screws, broken machine parts, and metal fragments may enter production materials and create risks for equipment damage and production instability.
Plastic and rubber materials are processed in different forms, including pellets, granules, powders, and recycled materials. High production speeds, abrasive materials, and continuous operation require reliable metal separation solutions to maintain stable manufacturing performance.
Detect and remove metal contaminants from plastic, rubber, and recycled materials to protect processing equipment, improve material quality, and ensure efficient production.
Removes ferrous and non-ferrous metal contaminants from free-falling plastic pellets, granules, powders, and recycled materials before further processing. COSO metal separators help prevent equipment damage and maintain consistent material quality in demanding industrial applications.
Detects ferrous, non-ferrous, and stainless steel contaminants in plastic and rubber production lines. COSO metal detectors provide reliable inspection for conveyor-based applications and help identify contamination sources before products move to the next production stage.
Ensures accurate weight control for packaged plastic products, rubber components, and finished materials. Precise weighing helps manufacturers reduce material waste, improve packaging consistency, and maintain production efficiency.
