Why are laboratory extruders important for research and development?
In research and development, only limited quantities of expensive raw materials are often available. Compact laboratory extruders enable the processing of small amounts of material while maintaining a high degree of process control. This allows for the development of formulations, the optimization of process parameters, and the preparation of scale-up strategies. Such systems are indispensable tools, particularly in the pharmaceutical industry, battery research, and materials development.
Advantages of Small Screw Diameters
Extruders with small screw diameters significantly reduce material consumption. This is particularly important for high-cost active ingredients, specialty polymers, or innovative battery materials. At the same time, the results can be scaled up to larger production facilities, thereby reducing development risks.
Three-Tec manufactures the world's smallest laboratory extruders, with screw diameters as small as 5 mm. Learn more about our Extruders.
Extruders in mechanochemistry
Mechanochemistry uses mechanical energy—such as shear forces, pressure, or intense mixing—to selectively modify materials or trigger chemical reactions. Compared to conventional methods, this approach allows for a reduction in or complete elimination of the use of solvents.
Twin-screw extruders, in particular, offer ideal conditions for mechanochemical processes. Through the controlled application of shear energy, temperature, and residence time, materials can be continuously mixed, modified, or made to react. This makes it possible to combine multiple process steps in a single system.
Typical applications include the modification of polymers, the production of composite materials, the development of battery materials, and low-solvent or solvent-free manufacturing processes. The combination of mechanochemistry and twin-screw extrusion opens up new possibilities for efficient, sustainable, and scalable material development processes, from the laboratory to production.

Extrusion for Meat Alternatives (Meat Analogues)
Extrusion is a key technology for the production of plant-based meat alternatives, also known as meat analogues. In this process, plant-based proteins—such as those derived from soy, peas, wheat, or other raw materials—are processed under specific temperature, pressure, and shear conditions. During the extrusion process, fibrous structures are formed that resemble various meat products in texture and bite.
Twin-screw extruders, in particular, are used because of their excellent mixing and processing capabilities. They enable the precise processing of complex formulations and ensure consistent product quality. The extrusion of meat analogues is used in both product development and industrial production, offering manufacturers a flexible platform for developing innovative and sustainable foods.

Extrusion and Electrospinning
Extrusion systems are increasingly being used to process polymers for electrospinning processes.
In this process, materials can:
- homogenized
- compounded
- modified
- formulated
before they are used to produce micro- or nanofibers.
Frequently Asked Questions
What is hot-melt extrusion, and what is it used for?
Hot-melt extrusion is a well-established process in pharmaceutical development. Among other things, it is used to improve the solubility of active ingredients, enable continuous manufacturing processes, and develop controlled-release formulations.
What are extruders used for in battery research?
In battery research, extruders are used to process, among other things, active materials, conductive additives, polymer binders, and solid electrolyte materials for the development of new cell concepts.
What is mechanochemistry, and what role does the extruder play in it?
Mechanochemistry uses mechanical energy, such as shear forces or pressure, to modify materials or trigger chemical reactions—often with reduced or no use of solvents. Twin-screw extruders provide ideal conditions for such processes through controlled shear energy, temperature, and residence time.
How are extruders used in the production of meat alternatives?
Plant-based proteins, such as those derived from soy, peas, or wheat, are extruded under specific temperature, pressure, and shear conditions. This process creates fibrous structures that mimic the texture and bite of meat products. Twin-screw extruders, in particular, are used here because of their mixing and processing capabilities.
What role does extrusion play in electrospinning?
Extrusion systems are used to homogenize, compound, modify, and formulate polymers for subsequent electrospinning processes before they are converted into micro- or nanofibers.
Why are small screw diameters particularly well-suited for research and development?
Small screw diameters significantly reduce material consumption, which is particularly important when working with expensive active ingredients, specialty polymers, or new battery materials. At the same time, the results can be reliably scaled up to larger production facilities.
