Dependable Recycling & Re-Pelletizing of Rigid & Contaminated Plastics
A Single Screw Extruder is the foundational machine of modern plastic processing and recycling — a precision-engineered system in which a single rotating screw conveys, melts, plasticizes, degasses, and homogenizes polymer material inside a heated barrel before forcing it through a die to form pellets, film, sheet, pipe, or profile. Compared to twin-screw machines, single screw extruders offer simpler construction, lower investment, easier maintenance, and lower energy consumption — making them the workhorse of plastic recycling and re-pelletizing applications worldwide, particularly when feedstock has been pre-cut and pre-conditioned into uniform regrinds or flakes.
Torontech offers a comprehensive single-screw extrusion portfolio engineered to handle the full spectrum of plastic recycling challenges. The Single Screw Extruder TT-ASE is the dependable standalone platform — combining plasticization and pelletizing in a single step, ideal for re-pelletizing crushed regrinds and flakes of PE, PP, ABS, PS, HIPS, PC, and PET. The Double Stage Cutter Compactor Recycling Pelletizing Line TT-ADS combines a cutter compactor with a single-screw extruder for high-quality processing of dense rigid flakes (100–1,000 kg/h based on screw diameter). The Excellent Degassing and Filtering Pelletizing Line TT-ASE PRO is the flagship — a super-long L/D single-screw platform with the proprietary SCF self-cleaning filtration system, double vacuum degassing zones, European Rittal IP54 electrical cabinet, and Bluetooth remote monitoring — purpose-built for the most contaminated and heavily printed plastic waste streams.
Every Torontech single-screw extruder is built around premium engineering: bi-metal screws and barrels with exceptional resistance to wear and corrosion; advanced single-screw designs delivering gentle plasticization and superior homogenization; high-strength hardened reducers with precision motor-to-gearbox couplings; intelligent PLC-based control systems; vacuum degassing zones; and configurable filtration options from single piston screens through dual-filter setups to fully automatic self-cleaning systems. The result is reliable, repeatable, regulator-ready pellet output — the foundation of every modern circular-economy recycling operation.
Re-Pelletize with Reliability & Precision
Every successful plastic-recycling operation depends on the consistent, reliable performance of a single, often-overlooked machine: the extruder that melts, mixes, degasses, filters, and pelletizes the recovered material into clean, uniform, market-ready granules. A poorly performing single-screw extruder means inconsistent pellet quality, lost batches, unplanned downtime, and a finished product that downstream customers won't accept. The recyclers and manufacturers who consistently deliver world-class recycled pellets are the ones equipped with single-screw extruders built for precision, durability, and around-the-clock industrial reliability — and the Torontech single-screw portfolio gives you exactly that.
Whether you are setting up a new recycling line for clean post-industrial scrap, upgrading an existing operation to handle dense flake feedstock, or commissioning a state-of-the-art line for heavily contaminated post-consumer waste, Torontech has the single-screw-extruder platform engineered to meet your exact needs. From the standalone TT-ASE to the double-stage TT-ADS and the flagship TT-ASE PRO, every Torontech machine delivers world-class extrusion performance backed by industry-leading service and support.
