PSF Extrusion Line
Developed for stable and economical production of filament by
complementing the shortcomings of one-on-one extrusion method
Characteristics
1. Stable production of high-quality products
2. Low production costs
3. Simple operation and maintenance
4. High efficiency of electricity consumption
5. Low loss rate
| DAESUNG EXT PSF Extrusion Line | Ordinary PSF Extrusion Line | |
|---|---|---|
| Technology(Patents) | 1. One set of 150mm Single Extrusion Machine ->8 sets of Spin Block 2. Automatic screen changer – continuous production  |
1. Small extrusion machine 6~8 sets 1:1 spin block loading 2. Screen changer loaded for each extrusion machine – Production not available while changing the screen – Waste of time. Raw materials, manpower and electricity  |
| Denier | Constant denier by continuous production | Much deviation of denier according to the time or replacement of screen |
| strong>Color | Same color by mixing done in one extrusion machine | Deviation of color due to separate mixing |
| Raw materials | Little loss of raw materials by continuous production | Waste of raw materials due to stoppage and restart of extrusion machine while each screen is replaced |
| Consumption of electricity | Power and heater SSR for one set of extrusion machine + Inverter control | Loss of heater heat due to power for each extrusion machine |
| Manpower | Automatic screen changer | Necessary to have exclusive manpower for replacement of several sets of screens |
| Easy manipulation and maintenance | Gear pump + Pressure sensor + Extrusion machine link system Gear pump: Possible to produce fiber in a certain denier, Oil, Easy cleaning and maintenance being installed outside the output block. |
Usually no gear pump. An experienced technician should check the denier of the extrusion machine all the time and decide the time to replace the screens. |
