Extrusion is a continuous process for processing plastics, polymers, powders, and blends. The material is conveyed by rotating screws, processed, and finally extruded through a die.Three-Tec extruders feature a compact design, high torque, and intuitive touch-panel operation. They are available with screw diameters ranging from 5 to 100 mm. Our laboratory equipment can process even the smallest quantities, starting at 1 gram, while our large-scale production systems can handle quantities of up to 2 metric tons.

They are particularly well-suited for simple extrusion processes and the production of filaments or profiles. Twin-screw extruders also offer intensive mixing, dispersing, and compounding capabilities. They are frequently used in the pharmaceutical industry, for battery materials, in research, and for sophisticated material formulations.\u00a0Single-screw extruders are suitable for:<\/strong> Laboratory extruders enable the development and optimization of new materials with minimal raw material consumption. They are used for material testing, feasibility studies, formulation development, and scale-up projects. Even the smallest quantities can be processed under conditions that closely mimic real-world applications. Three-Tec manufactures the world\u2019s smallest laboratory extruders, with screw diameters starting at just 5 mm.

This process transforms a raw material into a specific intermediate or final product.\u00a0What screw diameters are available for Three-Tec extruders?<\/strong>Three-Tec extruders are available with screw diameters ranging from 5 to 100 mm\u2014from laboratory equipment for very small quantities starting at 1 gram to production systems capable of handling up to 2 metric tons. Learn more about our Extruders<\/a>.\u00a0For which materials is extrusion suitable?<\/strong>Materials extruded include plastics, polymers, active pharmaceutical ingredient formulations, battery materials, food ingredients, as well as powders, granules, and material blends.\u00a0What are the main advantages of extrusion over other processes?<\/strong>Extrusion enables continuous production with high product quality, good reproducibility, and easy scaling from the laboratory to the production level.<\/p>\t\n\t For more information, please visit our page on the Extruders<\/a> and in the following news reports:Resource-saving extrusion with laboratory extruders from Three-Tec<\/a>Two screw diameters, one device: the Hybrid laboratory extruder<\/a>Special production: Extrusion in an ATEX environment<\/a>\n\t\t\t\tWhat is the difference between a single-screw and a twin-screw extruder?\n\t\t\t<\/h2>\n\t\t\t
