The PAR 20G&PAR 200G equipment is specifically designed to handle various high viscosity materials, utilizing reliable and mature technology for widely used quantitative precise feeding or quantitative mixing of materials. The PAR 20G&PAR 200G equipment is equipped with two sealed pressure plates, which can directly extract materials from the raw material barrel and mix them quantitatively. These two devices also have motor control, which can accurately control flow and injection volume, and can continuously output. In addition, PAR 20G and PAR 200G can also be connected to automation systems to achieve fully automatic or semi-automatic applications.
