About WAB-GROUP
Willy A. Bachofen AG Maschinenfabrik (WAB-GROUP) is a Swiss mechanical engineering company based in Muttenz near Basel, specializing in wet grinding and dispersion technology, three-dimensional mixing technology, and Flow Chemistry. The product portfolio includes the DYNO-MILL series stirred ball mills (including UBM, ECM-AP, KD, PHARMA, as well as laboratory and research models), the TURBULA 3D vibratory mixers (0.1–55 liters container volume) and dyna-MIX (40–1500 liters), the continuously inductively heated Mechanochemistry Reactor WAB IMPA°CT REACTOR, and Flow Chemistry solutions. The machines enable wet fine grinding and dispersion of pumpable products of low to high viscosity with particle sizes from 50 nanometers to 500 micrometers in completely closed systems. Research and development as well as production are located under one roof at the headquarters in Muttenz. In its own technical facility, test runs and process studies are carried out and process parameters are optimized for customer products. The international customer base comes from industries such as paints and varnishes, coatings, printing inks and inkjet, plant protection, pharmaceuticals, cosmetics, food, battery materials, life sciences, ceramics and electrical engineering, as well as cell lysis.
