Cost-effective compounding of powder coatings with the twin-screw compounder ZSK.
Constantly increasing cost pressures and the demand for maximum flexibility in the manufacturing of powder coatings require production
lines with the highest level of productivity. The development of new products for new fields of application – for example the automotive
industry – is progressing well with Coperion Werner & Pfleiderer (CWP) extruders. To meet these high market demands, Coperion Werner & Pfleiderer has developed the twin-screw compounder ZSK MEGAvolume with the largest free volume and at the same time the highest specific torque.
Since the successful market introduction of the ZSK MEGAvolume series in 2002, our customers have been using MEGAvolume ZSKs to produce extremely cost-effective powder coatings that satisfy the highest quality requirements.
| The success of the ZSK MEGAvolume technology is based on: |  |  |
| - | | Increased free volume through greater flight depth with optimized outside diameter/inside diameter ratio (Do / Di) |
| - | | Further increased screw speeds (up to max. 1,800/min) |
| - | | Longer processing section |
| - | | Optimized screw configuration |
| - | | Available either with separate controls or alternatively in a compact version with integrated controls |
Effect of raising speed from n = 900 min-1 to n = 1,200 min-1.
| Greater volume enhances quality and productivity | | |
The new ZSK MEGAvolume from Coperion Werner & Pfleiderer produces powder coatings of convincing homogeneity at clearly reduced production costs. Coperion Werner & Pfleiderer customers now get a clear competitive advantage.
| Advantages of the ZSK MEGAvolume series compared with the ZSK MEGAcompounder series: | | |
| - | | 50% higher throughput at the same extruder size, or alternatively, smaller extruder size for the same throughput and thus a shorter cleaning time |
| - | | Improved feeding of fines due to greater flight depth and higher speeds |
| - | | Greater flexibility in speed, residence time, and throughput |
| - | | Lower material temperatures, thus less product stress and improved product quality, depending on the product and the process |
| Plant for continuous production of powder coatings. | | |
