-A double-wave screw is a two-flight wave screw concept. The implementation in REX is relatively simple here, as the secondary flight is "stepped" over the entire length of the zone, similar to a barrier screw, i.e. the plastic can flow over the secondary flight continuously. The main flight is not recessed so that the conveying behaviour is only slightly affected. +A double-wave screw is a two-flight wave screw concept.

-The energy transfer screw is also a two-flight screw concept. In comparison to the double-wave screw, however, there is no division into main and secondary flights, but the flights are always recessed on the hopper side parallel to the channel height reduction to form a wave crest. This means that if there is a channel height reduction in a channel, the plastic always flows back into the neighbouring channel in the direction of the extruder hopper against the conveying direction. This reduces the specific throughput but achieves a high mixing effect.\\ +The energy transfer screw is also a two-flight screw concept.

-The speed can also be increased due to the lower conveying capacity compared to the double-wave screw. This allows a high melting capacity and a high mixing effect at the same time, especially with high throughputs.+The screw speed can also be increased due to the lower conveying capacity compared to the double-wave screw.
