Auxiliary machines for plastic recycling are the support equipment that makes a pelletizing or extrusion line function as a complete, high-efficiency system. While the extruder or pelletizer is the core processing machine, it is the upstream, downstream, and inline auxiliary units that determine line throughput, output quality, and production uptime. Without proper dehumidification, wet regrind causes hydrolysis and surface defects in the pellet. Without melt filtration, contaminants in post-consumer streams produce off-spec product or block dies. Without a controlled cutting system, pellet geometry varies, causing handling and dosing problems. Auxiliary machines address each of these requirements as dedicated, purpose-engineered units designed to integrate directly into standard recycling and extrusion line configurations.
Torontech's auxiliary machine portfolio spans six categories covering the full recycling line ecosystem. The TT-AWPC Wood-Plastic Profile Extrusion Line processes PVC resin blended with wood flour, rice husks, or calcium carbonate into WPC decking, fencing, and profiles with integrated VOC deodorization. The Dehumidification and Drying System conditions hygroscopic resins and moist regrind to below 0.02% moisture before extrusion. The TT-EPS Foam Recycling Pelletizing Machine converts low-density expanded polystyrene foam into dense, reusable PS pellets. The TT-ASD Film and Bag Recycling Squeezer mechanically dewaters wet LDPE film and bags after washing, preparing them for direct pelletizing. The Cutting System automates pelletizer speed via die-head pressure feedback for consistent pellet geometry and uses pneumatic blade clamping for extended blade life. The TT-SCF Self-Cleaning No-Mesh Melt Filter enables continuous-duty melt filtration of highly contaminated streams without production stops for screen changes.
Complete Your Recycling Line with Torontech
A recycling line is only as productive as its least capable component. Every batch of wet film that enters the extruder undried, every contaminated melt slug that reaches the die, and every off-size pellet that jams a downstream hopper represents waste — in energy, time, and material value. Torontech's auxiliary machine portfolio is designed to close those gaps: conditioning your material before the extruder, protecting your die and screw from contamination, and ensuring consistent, marketable pellets at the line end. Whether you are building a new WPC production line, upgrading a film recycling plant, adding dehumidification ahead of a PET extruder, or eliminating screen-change downtime with a self-cleaning melt filter, Torontech has the equipment and the world wide support network to deliver it. Contact Torontech today to discuss your line configuration, material stream, and production targets. Our plastics processing specialists will identify the right combination of auxiliary units — and back them with 20+ years of recycling line expertise.
Applications in Industries
Plastic Film & Bag Recycling Lines The TT-ASD squeezer dehydrates wet film after washing; the Cutting System produces uniform pellets from the melt strand; and the TT-SCF filters contaminated melts — three machines that together form a complete film-to-pellet line. | EPS / Polystyrene Foam Recycling The TT-EPS foam pelletizing machine melts and re-extrudes low-density expanded polystyrene into high-density, transportable, reusable PS pellets — dramatically reducing volume and converting waste foam into sellable secondary raw material. |
Wood-Plastic Composite (WPC) Manufacturing The TT-AWPC extrusion line processes PVC resin blended with wood flour, rice husks, or calcium carbonate into WPC decking, fencing, door profiles, and construction trim using VOC deodorization to meet indoor air quality requirements. | High-Contamination Plastic Recycling The TT-SCF self-cleaning melt filter removes solid contaminants from recycled melt streams without stopping the extruder for screen changes — critical for post-consumer streams where contamination levels make conventional screens impractical. |
Pre-Extrusion Conditioning The dehumidification and drying system prepares hygroscopic resins (PET, nylon, ABS, PC) and moisture-laden regrind for extrusion, preventing hydrolysis, surface defects, and reduced mechanical properties in the pelletized output. | Multi-Material Pelletizing Plant Optimization Any multi-step pelletizing plant benefits from the Cutting System's die-head pressure feedback for consistent pellet geometry, combined with upstream drying and downstream melt filtration — reducing rejects and improving pellet bulk density. |
Why Choose Torontech for Your Auxiliary Equipment Needs?
✔ Complete Recycling Line Ecosystem Torontech supplies the full auxiliary equipment chain: upstream drying (dehumidification system), in-line processing (TT-AWPC, TT-EPS, TT-ASD), melt filtration (TT-SCF), and pellet cutting (Cutting System) — all from one supplier, one support contact. | ✔ Continuous-Duty, No-Stop Operation The TT-SCF's self-cleaning, screenless filtration and the Cutting System's auto-speed control are engineered specifically to eliminate production stops, keeping your recycling line running at full output during peak production shifts. |
✔ Designed for Post-Consumer Streams Every auxiliary machine in Torontech's lineup is built to handle the variability of real-world recycled plastic: contaminated melts, wet film, low-bulk-density foam, and moisture-laden regrind — not just clean, well-sorted production scrap. | ✔ VOC and Environmental Compliance The TT-AWPC line includes a dedicated VOC homogenization and deodorization system for negative-pressure conveying and odor treatment, supporting WPC manufacturers who supply indoor building materials subject to VOC emission standards. |
✔ Fast International Parts & Support All Torontech auxiliary machines are supported from Toronto, Ontario, with parts warehoused in North America. No ocean freight delays for wear parts, blades, or control components — minimizing planned and unplanned downtime. | ✔ 20+ Years Plastics Processing Experience Torontech has been designing and supplying plastics recycling and processing equipment for over 20 years across the world.
