South America’s Unique PET Sheet Extrusion Requirements<\/h2>\n

South American packaging manufacturers face a set of conditions that differ substantially from European or North American markets. A machine that excels in Germany or the United States may underperform \u2014 or become economically unviable \u2014 in S\u00e3o Paulo or Buenos Aires. Three factors define the requirements:<\/p>\n

1. rPET content mandates.<\/strong> Brazil’s Decree No. 12,688 mandates 22% recycled PET content in bottles starting 2026. Argentina and Colombia are drafting similar legislation. This means any newly purchased extrusion line must process 100% post-consumer rPET bottle flakes without pre-drying \u2014 a capability single-screw extruders cannot deliver.<\/p>\n

2. Electricity cost sensitivity.<\/strong> Industrial electricity rates in Brazil and Argentina are among the highest in the Americas. An extrusion line’s installed power and actual consumption rate directly determine operating margins. A 250 kW installed system consuming at ∼70% actual rate (= 175 kW average) can save $15,000\u2013$30,000 annually versus less efficient alternatives.<\/p>\n

3. Voltage variability across countries.<\/strong> Unlike Europe’s harmonized 400V\/50Hz, South America presents a patchwork: Brazil uses 220V\/380V mixed (varying by state), Argentina is 380V\/50Hz, Chile runs 380V\/50Hz, while Peru uses 220V\/60Hz. A production line must be factory-configured to match each country’s industrial power standard \u2014 one preset cannot serve the entire continent.<\/p>\n

What Defines the Best PET Sheet Line for South America?<\/h2>\n

1. Twin-Screw Extruder: The Core Differentiator<\/h3>\n

The single most important decision is twin-screw vs. single-screw<\/strong> extrusion technology.<\/p>\n\n\n\n\n\n\n\n\n\n
Factor<\/th>\nSingle-Screw<\/th>\nParallel Twin-Screw (75mm, L\/D 40:1)<\/th>\n<\/tr>\n<\/thead>\n
rPET flake processing<\/td>\nRequires pre-drying, limited to ∼30% recycled content<\/td>\nDirect processing of 100% rPET flakes via vacuum degassing<\/td>\n<\/tr>\n
Melt homogeneity<\/td>\nDependent on screw design, less consistent<\/td>\nSuperior mixing and dispersion across full barrel length<\/td>\n<\/tr>\n
Output stability<\/td>\nFluctuates with material variation<\/td>\nConsistent output 350\u2013500 kg\/h regardless of feedstock<\/td>\n<\/tr>\n
Energy efficiency<\/td>\nHigher kWh\/kg for recycled material<\/td>\nLower specific energy consumption with PMSM drive motor<\/td>\n<\/tr>\n
Degassing capability<\/td>\nLimited or absent<\/td>\n3 vent ports + multi-stage vacuum system<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

A parallel co-rotating twin-screw extruder<\/a> with a 40:1 L\/D ratio, 132 kW permanent magnet synchronous motor (PMSM), and a high-torque gearbox rated at 10 N\u00b7m\/cm\u00b3 provides the shear force and residence time needed to homogenize rPET flakes while the vacuum degassing system removes moisture and volatiles inline \u2014 eliminating the energy cost of pre-drying.<\/p>\n

2. Output Capacity: 350\u2013500 kg\/h for the South American Sweet Spot<\/h3>\n

Most South American thermoforming converters operate 2\u20134 thermoforming lines producing cups, trays, and containers for food service and retail packaging. A sheet line delivering 350\u2013500 kg\/h<\/strong> matches this downstream capacity perfectly:<\/p>\n

    \n
  • One SWT-75S-1000 line feeds 2\u20133 thermoforming machines running standard cup\/tray production<\/li>\n
  • Sheet width up to 800 mm enables multiple-cavity thermoforming layouts<\/li>\n
  • Sheet thickness 0.2\u20132.0 mm covers the full range from thin-gauge disposable cups to thick-gauge reusable containers<\/li>\n<\/ul>\n

    Purchasing a larger machine (85mm+ screw, 600+ kg\/h) creates a bottleneck mismatch \u2014 the extruder overproduces while downstream thermoforming cannot keep pace, forcing idle time that erodes efficiency.<\/p>\n

    3. Full-Line Configuration: What the SWT-75S-1000 Includes<\/h3>\n

    A complete PET sheet extrusion turnkey system consists of 15 integrated components. The SWT-75S-1000 configuration delivers every unit required for immediate production:<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n

    rPET Capability: The Vacuum Degassing Advantage<\/h2>\n

    The multi-stage vacuum degassing system is what makes direct rPET flake processing possible. Here is why it matters:<\/p>\n

      \n
    1. Post-consumer PET flakes contain residual moisture (~0.5\u20131.5%) even after washing and mechanical drying<\/li>\n
    2. In a single-screw extruder, this moisture hydrolyzes the PET melt, reducing intrinsic viscosity (IV) and weakening the final sheet<\/li>\n
    3. The twin-screw extruder’s 3 vent ports connected to a 7.5 kW rotary-vane pump + 3 kW roots pump<\/strong> series system actively extracts moisture and volatiles from the melt before they cause IV degradation<\/li>\n
    4. The pre-filter system captures any remaining particulate, ensuring consistent melt quality<\/li>\n<\/ol>\n

      This eliminates the need for a separate pre-drying system \u2014 saving both capital cost (∼$25,000\u2013$40,000) and annual electricity consumption for a drying hopper (∼$8,000\u2013$12,000 per year at South American industrial rates).<\/p>\n

      Machine Construction: Materials That Matter<\/h2>\n\n\n\n\n\n\n\n\n\n

      Screw elements made from 38CrMoAlA with nitriding to HV 900\u20131000 provide the wear resistance necessary for processing recycled PET, which contains trace contaminants that accelerate screw and barrel wear. The shaft material (WR12) and spline connection provide the torque transmission reliability needed for 24\/7 production.<\/p>\n

      Control System: One-Touch Operation with Remote Monitoring<\/h2>\n

      The PLC control system on the SWT-75S-1000 is designed for South American manufacturing environments where skilled operators may be in short supply:<\/p>\n

        \n
      • 15-inch touchscreen<\/strong> with Chinese\/English interface \u2014 no language barrier for local operators<\/li>\n
      • One-touch line start<\/strong> with recipe data storage \u2014 reduces operator error during shift changes<\/li>\n
      • Data traceability and archive records<\/strong> \u2014 critical for food-contact packaging compliance (Mercosur GMC Res. 52\/99, ANVISA)<\/li>\n
      • Remote network monitoring<\/strong> \u2014 enables the manufacturer’s engineers in China to diagnose issues and adjust parameters without dispatching a technician to South America<\/li>\n<\/ul>\n

        Energy Efficiency: The PMSM Motor Advantage<\/h2>\n

        The 132 kW permanent magnet synchronous motor (PMSM) on the main drive delivers higher efficiency than conventional asynchronous induction motors, particularly at partial loads:<\/p>\n

          \n
        • PMSM efficiency: 94\u201396% across 50\u2013100% load range<\/li>\n
        • Conventional asynchronous motor: 88\u201392% in the same range<\/li>\n
        • Annual electricity savings at 175 kW average load, 6,000 operating hours: approximately 21,000\u201342,000 kWh<\/li>\n<\/ul>\n

          At Brazilian industrial electricity rates (∼$0.14\u20130.18\/kWh in 2026), this translates to $3,000\u2013$7,500 in annual savings \u2014 enough to cover the cost of one full spare parts kit over a 12-month period.<\/p>\n

          Voltage Configuration by Country<\/h2>\n

          A key differentiator for South American buyers: the SWT-75S-1000 is factory-configured to match each country’s specific industrial power standard. This is not a minor detail \u2014 importing a line pre-configured for the wrong voltage risks costly transformer retrofits and commissioning delays.<\/p>\n\n\n\n\n\n\n\n\n\n\n
          Country<\/th>\nCommon Industrial Voltage<\/th>\nConfiguration Required<\/th>\n<\/tr>\n<\/thead>\n
          Brazil<\/td>\n220V\/380V (varies by state)<\/td>\nSpecify state-level standard at order<\/td>\n<\/tr>\n
