The working principle of the flame retardant kneading machine is based on the effects of high temperature, high pressure, and shear force. It mixes two or more polymer materials with different components together, and through strong kneading and stirring, they are fully mixed, reacted, and compatible, ultimately forming a uniform composite material.

The screw discharge kneading machine is equipped with a screw extrusion setting under a pair of cooperating and rotating blades. After the kneading machine is mixed or kneaded, the material can be extruded through this screw, which is quite convenient to operate. For hydraulic and manual flipping cylinders, it greatly improves production efficiency and can also reduce the disadvantages of inconvenient and unclean discharge to a greater extent.
