Overview
The Eurotech D25–D35 Single-Layer Cast Film Line is a compact, modular laboratory and pilot-scale extrusion system engineered for the precision production of thin polymer films and foils via the cast film process. Unlike blown film or calendering methods, this line employs a melt-extrusion–quench–wind architecture: molten polymer is extruded through a flat die onto a chilled chrome-coated casting drum, rapidly solidified by controlled contact cooling, and subsequently wound into uniform rolls. The system supports both vertical and horizontal configurations—enabling flexible integration into limited-footprint R&D labs or quality control environments—while maintaining full process traceability and thermal stability critical for structure–property correlation studies in polyolefins, PET, TPU, and specialty barrier resins.
Key Features
- Modular extrusion platform with interchangeable single-screw (D25 or D35) and optional E-lab co-rotating twin-screw extruder modules for enhanced melt homogenization and thermal sensitivity control;
- Integrated gear pump for precise volumetric metering and pressure stabilization upstream of the flat die—ensuring ±0.5% thickness consistency across web widths up to 300 mm;
- Manually operated melt filtration unit (mesh size configurable per material requirements) positioned between extruder and pump to remove gels and contaminants without introducing backpressure spikes;
- Casting drum assembly with independent temperature control (±0.3 °C) and surface finish Ra ≤ 0.05 µm, optimized for high-gloss, low-haze film surfaces;
- Dual- or triple-roll winding station supporting either continuous rewind (with dancer-controlled tension feedback) or guillotine-style cut-to-length operation for paper-like substrates;
- Stainless-steel frame with CE-compliant guarding, emergency stop circuitry, and integrated HMI for real-time monitoring of screw speed, melt temperature zones (4 zones), drum surface temp, and line speed.
Sample Compatibility & Compliance
The D25–D35 line accommodates thermoplastic polymers with melt flow rates (MFR) ranging from 0.5 to 50 g/10 min (ASTM D1238, 190 °C/2.16 kg), including LDPE, HDPE, PP homopolymers and copolymers, PS, ABS, and engineering grades such as PC and PEEK (with appropriate barrel configuration). All wetted components—including screw barrels, die lips, and drum surfaces—are constructed from nitrided tool steel or electroless nickel-plated alloys to resist corrosion and abrasion during extended processing of filled or abrasive compounds. The system complies with EU Machinery Directive 2006/42/EC, EN 61000-6-2 (EMC immunity), and EN 61000-6-4 (EMC emissions). Optional IQ/OQ documentation packages are available to support GLP and ISO 17025-accredited lab validation protocols.
Software & Data Management
Control is managed via a dedicated Eurotech HMI running embedded Linux OS with deterministic real-time loop execution. Process parameters—including screw RPM, zone temperatures, gear pump speed, drum surface temperature, and line speed—are logged at 1 Hz resolution and exported in CSV or XML format via USB or Ethernet. The system supports optional OPC UA server integration for seamless data ingestion into LIMS or MES platforms. Audit trails record all parameter changes, operator logins, and alarm events—fully compliant with FDA 21 CFR Part 11 requirements when paired with user authentication and electronic signature modules. No cloud connectivity is enabled by default; all data remains on-device unless explicitly configured for secure local network transfer.
Applications
- R&D-scale formulation development for barrier films, heat-seal layers, and metallizable substrates;
- Process window mapping for new resin grades prior to full-scale production ramp-up;
- Quality assurance testing of incoming polymer batches for melt stability, gel content, and optical uniformity;
- Evaluation of additive dispersion efficiency (e.g., slip agents, antiblock, UV stabilizers) under realistic shear–thermal history;
- Pre-commercial prototyping of medical-grade films requiring ISO 10993-compliant processing conditions;
- Academic research on crystallization kinetics and skin–core morphology development in quenched polymeric melts.
FAQ
What is the maximum achievable film width and typical thickness range?
Film width is configurable up to 300 mm depending on die design; thickness ranges from 25 µm to 500 µm, controllable via line speed, pump output, and chill drum temperature.
Can the system be upgraded to accommodate multi-layer coextrusion?
The D25–D35 base platform is single-layer only; Eurotech offers the D25–D35-Multi variant with three extruders and a feedblock die for up to three-layer structures—requires separate quotation and mechanical reconfiguration.
Is technical support and spare parts availability guaranteed outside the EU?
Yes—Eurotech maintains authorized service partners in North America, China, India, and Brazil, with lead times for critical spares (screws, dies, pump gears) under 6 weeks ex-warehouse Milan.
Does the line include calibration certificates for temperature and speed sensors?
All RTDs and encoder-based speed sensors are supplied with factory calibration reports traceable to NIST and PTB standards; on-site verification services are available upon installation.
What utilities are required for operation?
Standard requirements: 3-phase 400 V AC ±10%, 50/60 Hz; chilled water supply (8–12 °C, 3 bar, ≥1.5 m³/h); compressed air (6–7 bar, oil-free, 120 L/min); exhaust ventilation for volatiles (optional activated carbon filter kit available).
