Compared to hydraulic tilting discharge type, 5L screw discharge sigma mixer overcome a common industry challenge: the tendency for high-viscosity materials to adhere to vessel walls and the difficulty of achieving complete discharge. By utilizing screw reversal for mixing and forward rotation for extrusion, these machines not only ensure 100% efficient material discharge but also enable direct extrusion molding (e.g., into strands or pellets) when paired with a die, thereby significantly enhancing laboratory efficiency and testing accuracy.
