A PET levha ekstrüzyon makinesi is a complete industrial production line engineered to convert PET resin or recycled PET flakes into continuous, uniform flat sheets for thermoforming food-grade packaging. For South American manufacturers navigating rPET mandates, high industrial electricity costs, and Mercosur import compliance, the 75mm parallel twin-screw extruder line — with its 350–500 kg/h output, direct rPET flake processing capability, and customizable country-specific voltage configuration — represents the optimal balance of capital efficiency, regulatory readiness, and production flexibility for converters serving domestic and export markets across Brazil, Argentina, Colombia, Chile, and Peru.
South America’s Unique PET Sheet Extrusion Requirements
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 — or become economically unviable — in São Paulo or Buenos Aires. Three factors define the requirements:
1. rPET content mandates. 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 — a capability single-screw extruders cannot deliver.
2. Electricity cost sensitivity. 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–$30,000 annually versus less efficient alternatives.
3. Voltage variability across countries. 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 — one preset cannot serve the entire continent.
What Defines the Best PET Sheet Line for South America?
1. Twin-Screw Extruder: The Core Differentiator
The single most important decision is twin-screw vs. single-screw extrusion technology.
| Faktör | Single-Screw | Parallel Twin-Screw (75mm, L/D 40:1) |
|---|---|---|
| rPET flake processing | Requires pre-drying, limited to ∼30% recycled content | Direct processing of 100% rPET flakes via vacuum degassing |
| Melt homogeneity | Dependent on screw design, less consistent | Superior mixing and dispersion across full barrel length |
| Output stability | Fluctuates with material variation | Consistent output 350–500 kg/h regardless of feedstock |
| Energy efficiency | Higher kWh/kg for recycled material | Lower specific energy consumption with PMSM drive motor |
| Degassing capability | Limited or absent | 3 vent ports + multi-stage vacuum system |
A parallel co-rotating twin-screw extruder with a 40:1 L/D ratio, 132 kW permanent magnet synchronous motor (PMSM), and a high-torque gearbox rated at 10 N·m/cm³ provides the shear force and residence time needed to homogenize rPET flakes while the vacuum degassing system removes moisture and volatiles inline — eliminating the energy cost of pre-drying.
2. Output Capacity: 350–500 kg/h for the South American Sweet Spot
Most South American thermoforming converters operate 2–4 thermoforming lines producing cups, trays, and containers for food service and retail packaging. A sheet line delivering 350–500 kg/h matches this downstream capacity perfectly:
- One SWT-75S-1000 line feeds 2–3 thermoforming machines running standard cup/tray production
- Sheet width up to 800 mm enables multiple-cavity thermoforming layouts
- Sheet thickness 0.2–2.0 mm covers the full range from thin-gauge disposable cups to thick-gauge reusable containers
Purchasing a larger machine (85mm+ screw, 600+ kg/h) creates a bottleneck mismatch — the extruder overproduces while downstream thermoforming cannot keep pace, forcing idle time that erodes efficiency.
3. Full-Line Configuration: What the SWT-75S-1000 Includes
A complete PET sheet extrusion turnkey system consists of 15 integrated components. The SWT-75S-1000 configuration delivers every unit required for immediate production:

rPET Capability: The Vacuum Degassing Advantage
The multi-stage vacuum degassing system is what makes direct rPET flake processing possible. Here is why it matters:
- Post-consumer PET flakes contain residual moisture (~0.5–1.5%) even after washing and mechanical drying
- In a single-screw extruder, this moisture hydrolyzes the PET melt, reducing intrinsic viscosity (IV) and weakening the final sheet
- The twin-screw extruder’s 3 vent ports connected to a 7.5 kW rotary-vane pump + 3 kW roots pump series system actively extracts moisture and volatiles from the melt before they cause IV degradation
- The pre-filter system captures any remaining particulate, ensuring consistent melt quality
This eliminates the need for a separate pre-drying system — saving both capital cost (∼$25,000–$40,000) and annual electricity consumption for a drying hopper (∼$8,000–$12,000 per year at South American industrial rates).
Machine Construction: Materials That Matter
| Bileşen | Malzeme | Treatment | Hardness |
|---|---|---|---|
| Screw Elements | 38CrMoAlA | Quench & Temper + Nitriding (0.4–0.6mm depth) | HV 900–1000 |
| Shaft | WR12 | High-torque rated | HB 360–390 |
| Barrel | 38CrMoAlA | Quench & Temper + Nitriding (0.4–0.6mm depth) | HV 950–1050 |
| Calender Rolls | Alloy Steel | Mirror polish + Chrome plating (≥ 0.08mm) | HRC 55–62 |
| Die Lip | Tool Steel | Chrome plating (0.025–0.05mm) | — |
Screw elements made from 38CrMoAlA with nitriding to HV 900–1000 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.
Control System: One-Touch Operation with Remote Monitoring
The PLC control system on the SWT-75S-1000 is designed for South American manufacturing environments where skilled operators may be in short supply:
- 15-inch touchscreen with Chinese/English interface — no language barrier for local operators
- One-touch line start with recipe data storage — reduces operator error during shift changes
- Data traceability and archive records — critical for food-contact packaging compliance (Mercosur GMC Res. 52/99, ANVISA)
- Remote network monitoring — enables the manufacturer’s engineers in China to diagnose issues and adjust parameters without dispatching a technician to South America
Energy Efficiency: The PMSM Motor Advantage
The 132 kW permanent magnet synchronous motor (PMSM) on the main drive delivers higher efficiency than conventional asynchronous induction motors, particularly at partial loads:
- PMSM efficiency: 94–96% across 50–100% load range
- Conventional asynchronous motor: 88–92% in the same range
- Annual electricity savings at 175 kW average load, 6,000 operating hours: approximately 21,000–42,000 kWh
At Brazilian industrial electricity rates (∼$0.14–0.18/kWh in 2026), this translates to $3,000–$7,500 in annual savings — enough to cover the cost of one full spare parts kit over a 12-month period.
Voltage Configuration by Country
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 — importing a line pre-configured for the wrong voltage risks costly transformer retrofits and commissioning delays.
| Ülke | Common Industrial Voltage | Configuration Required |
|---|---|---|
| Brazil | 220V/380V (varies by state) | Specify state-level standard at order |
| Argentina | 380V / 3-Phase / 50Hz | Standard 380V configuration |
| Şili | 380V / 3-Phase / 50Hz | Standard 380V configuration |
| Peru | 220V / 3-Phase / 60Hz | Custom 60Hz motor configuration |
| Colombia | 440V / 3-Phase / 60Hz | Custom voltage + frequency |
| Ecuador | 220V/480V / 3-Phase / 60Hz | Specify at order |
Each line is built to the customer’s specific country requirements at the factory — no on-site transformer modifications needed.
SSS
Güney Amerika’da PET levha ekstrüzyonu için ideal vida çapı nedir?
For most South American thermoforming converters, a 75mm parallel twin-screw extruder with a 40:1 L/D ratio is the optimal choice. It delivers 350–500 kg/h output — matching the capacity of 2–3 downstream thermoforming lines — with the torque and residence time needed to process 100% rPET flakes without pre-drying. Larger screw diameters (85mm+) produce excess capacity that creates production bottlenecks unless the customer operates 5+ thermoforming lines simultaneously.
Can this machine process 100% recycled PET bottle flakes?
Yes. The multi-stage vacuum degassing system (7.5 kW rotary-vane pump + 3 kW roots pump) combined with 3 vent ports on the extruder barrel actively extracts moisture and volatiles from the melt. This eliminates the need for a separate pre-drying system and maintains PET intrinsic viscosity (IV) during processing — a capability single-screw extruders cannot match.
What is the machine’s power consumption and how does it affect operating costs?
Installed power is approximately 250 kW, with actual consumption at ∼70% (≈175 kW average) during normal operation. The 132 kW PMSM main drive motor operates at 94–96% efficiency across the load range. At Brazilian industrial electricity rates, annual electricity costs are approximately $147,000–$189,000 for 6,000 operating hours — $3,000–$7,500 less per year than comparable systems with conventional asynchronous motors.
Güney Amerika’da kurulum ve devreye alma işlemleri ne kadar sürer?
On-site installation and commissioning typically requires 10–14 working days with 1–2 dispatched engineers, assuming the customer has prepared the foundation, utilities (water, electricity, compressed air), and overhead crane access per the installation drawing. Customers must complete preparatory groundwork before the engineering team arrives to avoid delays.
Makine, Mercosur ithalat şartlarına uygunluk sertifikasına sahip mi?
The manufacturer holds EU CE certification and ISO 9001 quality management certification. Mercosur-specific documentation — including IRAM-NM compliance for Argentina and ANVISA-compatible food-contact documentation for Brazil — is provided with each shipment. The manufacturer’s export experience across 80+ countries includes regular shipments to South American markets.
What sheet thickness range can this machine produce?
0.2 mm to 2.0 mm, covering the full spectrum from thin-gauge disposable cup stock to thick-gauge reusable container sheets. The three-roll polishing calender (L-type, Ø350/Ø500/Ø500mm, mirror polish ≤ Ra 0.025 μm) combined with the hydraulic gap adjustment system ensures consistent thickness across the full sheet width.
How does PLC remote monitoring work for South American customers?
The 15-inch touchscreen PLC system supports network-based remote access, allowing the manufacturer’s engineers in China to connect to the machine in real time. They can view operating parameters, alarm logs, and production data — even adjust settings remotely. This reduces the need for on-site service visits and is particularly valuable for customers in remote locations within Brazil, Argentina, or the Andean region.
What spare parts are included and how quickly can additional parts be delivered to South America?
The standard spare parts kit includes: die tool set, 2 contactors, 2 relays, 2 circular cutter blades, and 2 heating rods. Additional spare parts can be shipped via air freight to major South American cities (São Paulo, Buenos Aires, Santiago, Lima) in 5–10 business days. The manufacturer maintains a dedicated export logistics team familiar with Mercosur customs clearance procedures.
