The laboratory extruder is designed for trial or entry level users, or for small scale production of masterbatches and some additive masterbatches. The modular design makes it very flexible for different formulations.

1. Low price: single-screw extruders are compact and inexpensive. Twin-screw extruders are more than twice as expensive as single-screw extruders.2. Simple recipe: single-screw extruders have a relatively simple process and recipe3. wide range of applications: single screw is suitable for melt extrusion of polymers, for extrusion processing of pellet feed, such as forming, film blowing machines, injection processing, etc., and for a wide range of applications of raw materials.4. Easy maintenance: In terms of maintenance, the single screw is simpler than the twin screw because the structure of the single screw is very simple and facilitates maintenance.5. Basic principle of conveying: The conveying of single-screw extruders depends on the sliding friction formed between the raw material and the barrel.

The Triple screws of the Ecoextruders series of co-rotating parallel three-screw extruders are arranged in a "one" shape and rotate at high speed in the same direction, subjecting the material to intense shearing, squeezing, kneading and grinding action for better homogenisation and dispersion. Compared to conventional twin-screw extruders, the triple-screw extruder has an additional high shear zone, which doubles the plasticising and mixing performance of the twin-screw extruder, resulting in high output and twice the capacity of the twin-screw extruder. The de-volatilisation efficiency is also significantly higher due to the increased specific surface area and increased surface renewal rate.

Certain polymers require pelletizing to be carried out under conditions without water and moisture, so that the extrusion system should have sufficient cooling capacity to cater for in this process; some materials are sorted into shear-sensitive or heat-sensitive categories. Two Stage Screw Extrusion System is deigned for such processes. Primary twin screw extruder provides mixing and dispersion without over-shear, lower speed single screw extruder provides enough cooling and pressure accumulation.
