What is Cast Film Extrusion Line
A cast film extrusion line is a flat-die process that extrudes molten resin onto cooled chill rolls to rapidly form a uniform film.This route has become a mainstream way to make flexible packaging and technical films because it delivers high line speeds, excellent clarity and thickness uniformity, and it integrates readily with downstream operations (e.g., laminating, coating, embossing, printing). Power your film program with JwellMech cast-film platforms: monolayer cast for clear, uniform films; co-extrusion/co-casting to build 2–5 layers in one pass; and coating-lamination lines integrating inline coating/laminating (optional embossing) for application-ready composites. Share your resin, width, thickness, and target speed—we’ll configure the optimal line.
JWELL TPU Film Solutions
Cast Film Extrusion
Flat-die extrudes molten TPU onto cooled chill rolls for rapid quenching, yielding clear, uniform films at high speeds with precise thickness control.
Coextrusion
Multiple extruders feed a co-extrusion block and slot die to build 2–5-layer TPU films in one pass, tuning hardness, tie-layers, barrier, and optics without secondary lamination.
Extrusion Lamination
Cast film bonds inline to fabrics or films via extrusion coating/laminating (optional embossing), delivering application-ready composites in a single run.
JWELL TPU Film Extrusion Line Series
Comfortably handling various coatings ranging from small to large products, its rich product lineup contributes to the automation of the coating process.
Cast Film Extrusion - TPU Medical Film Production Line
Engineered for medical-grade clarity and consistency, this flat-die cast line melts TPU and casts the melt onto polished, water-cooled chill rolls for rapid quenching and uniform gauge. A medical configuration adds melt filtration/pump, IR/Beta thickness measurement with AGC, corona treatment, closed-loop tension, and optional cleanroom enclosure and HEPA filtration—delivering low-gel, low-particulate films ready for downstream converting. Typical applications include wound-dressing backings, medical tape carriers, catheter jackets, wearable-sensor substrates, surgical drape components, and device protection films. The line integrates smoothly with printing, slitting, and lamination; width, thickness range, and line speed are fully customizable to your resin and compliance needs. Available options include release-film unwinds, inline edge-trim recycling, gravimetric dosing for additives, and data logging for traceability—helping you scale high yield, repeatable medical TPU film production.
Coextrusion - TPU Invisible Car Coating (PPF) Film Production Line
Purpose-built for premium automotive paint-protection film, the JwellMech Coextrusion PPF Production Line co-casts 2–5 layers in one pass via a multi-extruder feedblock and precision flat die, then rapidly quenches on mirror-polished chill rolls for low haze and tight gauge. A production-grade stack—melt filtration with gear pump, vacuum box or air knife, IR/Beta gauge with AGC, corona, closed-loop tension, clean winding—and optional inline single/double release-liner lamination yields conversion-ready rolls that integrate cleanly with primer/top-coat. The line scales across OEM/Tier-1 supply, kit converting for film brands (slitting/plotting), high-throughput installer networks, luxury aftermarket styling, fleet protection, and motorcycle/outdoor gear.
Extrusion Lamination - TPU/TPE Leather Extrusion Composite Production Line
JwellMech’s Extrusion Lamination—TPU/TPE Leather Composite Line is a solvent-free, one-step system that extrudes TPU/TPE through a precision flat die and bonds it inline to textiles or release film; it includes melt filtration with gear pump, web guiding, IR/Beta gauge with AGC, corona, closed-loop tension, hot-calendering, and optional embossing. It produces uniform-gauge, high-peel synthetic leather for automotive interiors, footwear uppers, bags & luggage, furniture upholstery, and sports/outdoor goods.
Why Choose JWELL TPU Film Extrusion Line Series
Unified Platform, Lower TCO
A common flat-die/chill-roll base, shared controls, and interchangeable spares across lines cut training, maintenance, and inventory—reducing total cost of ownership.
Modular Scalability Across Processes
Add extruders, feedblocks, coating/lamination and embossing modules to evolve from Cast Film to Coextrusion (2–5 layers) to Extrusion Lamination on the same architecture.
End-to-End Inline Integration
Melt filtration & gear pump, IR/Beta gauge with AGC, corona, web guiding, closed-loop tension, release-liner lamination, and clean winding deliver conversion-ready rolls with fewer secondary steps.
Application-Validated & Compliance-Ready
Pre-engineered packages for medical films, PPF, TPU/TPE synthetic leather, and glass interlayers, plus data logging/traceability and cleanroom/VOC-free options to meet demanding standards.
