本文叙述了单螺杆挤出机的塑化原理，并给出了最近在HELIBAR -50×34 D挤出机上的实验结果。他们证明，只需一个屏障螺杆，就可以成功地加工最不同的热塑性聚合物，具有非常高的产量、良好的工艺稳定性、低熔融温度和良好的熔融均匀性。这涉及标准聚合物（PE、PP、PS）和所谓的技术聚合物（PA、PC、PET、PBT、PMMA）以及软聚合物和弹性体（PVC-W、PUR、TPE、伊娃）。此外，该系统在一个标准的设计，成功地测试了一个快速运行的注塑机<$70 × 23 D与不同的聚合物（PS，PP，PE-HD）。与以前的高性能螺杆相比-在相同的安装驱动功率下-实现了更低的熔体温度，良好的熔体均匀性和20%至100%的塑化能力增强。
Abstract The plasticating principle, named HELIBAR for single-screw-extruders [1 to 5] is described and recent experimental results with a HELIBAR - extruder Ø 50×34 D are presented. They prove, that with only one barrier-screw the most different thermoplastic polymers can be processed successfully with very high throughput, good process stability, low melt-temperature and good melt-homogeneity. This concerns standard polymers (PE, PP, PS) and so-called technical polymers (PA, PC, PET, PBT, PMMA) as well as soft polymers and elastomers (PVC-W, PUR, TPE, EVA). Besides, this system in a standard design was tested successfully with a fast-running injection moulding machine Ø 70 × 23 D with different polymers (PS, PP, PE-HD). Compared to previous high-performance screws - with the same installed driving power - lower melt temperatures, good melt homogeneities and enhancements of the plasticating power between 20% and 100% were achieved.
