Single-screw laboratory extruders provide consistent data during the extrusion process, helping to verify process parameters such as speed, energy, and temperature for unfamiliar materials. These extruders are ideal for producing small quantities of new polymers, including strands, sheets, pellets, and blown films, in research and development. Equipped with measuring ports for melt pressure and melt temperature, these extruders allow the study of process parameters along the extruder barrels, which come in different lengths (length/diameter ratios). A die can be connected at the end of the extruder barrel to form the polymer melt into strands or films. Special rheological dies (such as slit, rod, or x-die) enable the measurement of shear and elongational viscosity at defined shear rates. A variety of screw geometries are available to customize the extrusion process, including different compression ratios, venting, and mixing sections. Wear-reduced screws and barrels extend the system’s lifespan. Standard pellet feeders, along with specialized feeding systems for powders, pastes, liquids, or highly viscous rubber, complete the setup.
