Ducting for Polymer and Plastics Processing

Ducting for polymer and plastics applications

The polymer and plastics industry faces significant air‑quality and safety challenges throughout production, processing, and finishing operations. Machining, cutting, grinding, and regrinding generate fine plastic dust, microplastics, and lightweight particles that easily become airborne and may be combustible or electrostatically charged. Pellet handling and material conveying create additional dust and fines, while extrusion, injection moulding, and thermoforming release fumes, vapours, and VOCs when polymers are heated. Without effective extraction, these contaminants can compromise worker health, increase fire and explosion risks, contaminate products, and lead to excessive maintenance and regulatory compliance issues.

Nordfab’s ducting solutions help plastics manufacturers control these risks through efficient, source‑capture and reliable process ventilation. Laser‑welded Quick‑Fit ducting with smooth, leak‑tight interiors minimises dust accumulation, reduces static pressure loss, and prevents material build‑up inside the system. High Vacuum solutions enable precise extraction of fine dust, regrind particles, and microplastics directly at the source, while sealed and corrosion‑resistant ducting options support fume and VOC removal in thermal processes. The modular, reusable Quick‑Fit design allows fast installation, easy cleaning, and flexible reconfiguration as production layouts evolve—helping polymer and plastics facilities maintain safer working conditions, stable airflow, and long‑term operational efficiency.

Critical extraction points in polymer and plastics industries:

Machining, cutting, and grinding stations. Trimming, routing, sawing, and grinding of plastic parts generate fine plastic dust, chips, and microplastics. These particles are often lightweight, electrostatically charged, and easily airborne, requiring efficient source‑capture extraction to protect workers and prevent accumulation inside ducting.
Pellet handling, conveying, and transfer points. Transporting plastic pellets, granules, and regrind material creates dust and fines when materials collide or abrade during conveying and loading. Without proper extraction, these fine particles can spread through the facility, increasing housekeeping demands and explosion risks.
Regrinding, granulation, and size reduction areas. Grinding scrap plastic into regrind produces high concentrations of fine dust and fragmented particles. These dusts can be combustible and prone to static build‑up, making controlled extraction critical for fire prevention and system reliability.
Extrusion, injection moulding, and thermoforming exhaust points. Heating and melting polymers release fumes, vapours, and decomposition by‑products such as VOCs. Local exhaust ventilation is required at machine vents, hoppers, and die heads to remove fumes before they spread into the workspace.
Part finishing and cleaning areas. Abrasive cleaning, deburring, and surface finishing operations generate additional fine dust and fibres. Without effective extraction at these points, contaminants can affect product quality, worker health, and downstream processes.

Quick-Fit (QF) ducting — x2 installation speed

Designed for speed and simplicity, the QF system clamps together in seconds without welds, bolts, screws, special tools, precise measurements, or specialised skills needed. Ready sections and rolled lips simplify alignment and reduce installation complexity. It cuts installation time — and duct-related downtime — by more than 45% compared to traditional ductwork. These efficiencies make Quick-Fit more economical, with lower labour costs and quicker project turnaround.

Quick-Fit ducting — reusable solution

Quick-Fit ducting enables rapid reconfiguration and reuse, being ideal for dynamic plant environments. When maintenance is required, sections can be quickly dismantled, cleaned out, and fastened back without tools, ensuring ease of use. Faster installation means reduced downtime, lower labour costs, and quicker project turnaround. Built with strong, continuous welds, QF ducting components maintain their shape and strength after multiple installation cycles without deformation or leaks. It makes feasible to reinstall or relocate Quick-Fit ducting systems many times, ensuring one of the lowest life cycle costs on the market and helping to avoid overconsumption — perfect for modular and adaptable building designs. For plant managers and maintenance teams, Quick-Fit ducting isn’t just a technical upgrade — it’s a smarter investment in operational reliability and long-term savings.

Quick-Fit Ball Joint — 360° performance

Nordfab Quick-Fit Ball Joint provides an effective solution to kinking and tearing in flexible duct as it minimizes friction between moving parts and extends the lifespan of the machinery. Ball Joint allows a 360 degree movement between flex hose and duct, which results in smoother operation and improves performance rate and overall efficiency. Ball Joint can connect Quick-Fit ducting or flex hose to allow the rotation of a dust or fume hood, allowing for quick and easy access during cleaning and maintenance. QF connections and clips of the Ball Joint allow for quick and easy access during cleaning and maintenance while local manufacturing makes it easier to ensure high-quality standards and lower carbon footprint.
