About Three-Tec
Three-Tec GmbH develops and manufactures at its Swiss site in Seon AG dosing devices, extruders, process equipment and customer-specific special systems such as isolators for high-containment applications and filling systems. In-house development, manufacturing and programming from a single source enable customer-specific solutions and short response times. The portfolio includes gravimetric and volumetric dosing devices as well as extruders for micro quantities through to production scale, including wet and melt granulation and mixing technology. In addition, the company operates a test laboratory offering services such as feasibility studies, process development and contract manufacturing. Typical areas of application are pharmaceuticals, the chemical industry and food processing, for example extrusion for plant-based meat alternatives or mechanochemistry. Training as well as service and maintenance complete the offering.
