Various raw materials and applications make mixing using impingement injection impossible. This is the case, for example, when casting systems or high-viscosity components are used. For many reactive components and additives - e.g., in continuous slabstock lines - mixheads are fitted with special stirrers to ensure that the reactive systems and additives are mixed homogeneously in the mixing chamber and a laminar output is achieved. To a certain extent, processors can influence factors such as the cell structure and cell size of foaming systems by means of particular types of stirrer. High-strength stirrers are used in compact and cellular elastomer systems, ensuring optimal results even when the processing parameters are extremely difficult.
Right from the start, MEL mixheads are equipped with a hydraulic control of the mixhead injectors for extremely short and synchronous switching cycles. This is a novelty that guarantees the processor a superior metering quality. Moreover, MEL mixheads are also fitted with a sophisticated...
