Product Overview - PSF extrusion line
PSF extrusion line
A 3D to 30D recycled staple fiber production line for synthetic leather, automotive interiors, industrial felt, and civil engineering fibers.
PSF extrusion line
Developed to overcome the drawbacks of one-to-one extrusion, enabling stable quality and cost-effective recycled staple fiber production.
Features

Comparison
Daesung EXT vs standard PSF line
A comparison focused on production stability, energy efficiency, and operating labor.
| Category | Daesung EXT PSF line | Standard PSF line |
|---|---|---|
| Technology (patent) | One 150mm single extruder -> 8 spin blocks Automatic screen changer - continuous production  | 6 to 8 small extruders with 1:1 spin blocks Each extruder uses a screen changer - production stops during swaps Waste of time, materials, labor, and power  |
| Denier | Consistent denier thanks to continuous production | Large denier variation depending on screen change timing |
| Color | Mixing in one extruder keeps color consistent | Separate mixing causes color variation |
| Raw material | Minimal material loss thanks to continuous production | Material wasted during stop/start for screen changes |
| Power consumption | Single extruder power with heater SSR + inverter control | Power per extruder with heater heat loss |
| Labor | Automatic screen changer | Dedicated labor needed to change multiple screens |
| Easy operation and maintenance | Gear pump + pressure sensor + linked extruder system Gear pump: consistent denier fiber production External oil thermal block for easy cleaning and maintenance | Typically no gear pump Experienced technician needed to check denier and screen changes |
