Extruder energy saving can be divided into two parts: one is the power part, one is the heating part.
Power part of the energy-saving: most of the inverter, energy-saving method is by saving motor energy consumption, for example, the actual power of the motor is 50Hz, and you actually need only 30Hz in production is enough, and those extra energy consumption in vain Wasted, the inverter is to change the power output of the motor to save energy.
Heating part of the energy-saving: Most of the heating part of the energy-saving electromagnetic heater is energy-saving, energy saving rate of about 30% to 70% of the old resistance ring.
Plastic material from the hopper into the extruder, driven by the rotation of the screw to move forward, the material in the forward movement of the process, to accept the heating cylinder, the screw caused by the shear and compression of the role of the material melting , Thus achieving the change between the three states of the glassy state, the high-elastic state and the viscous flow state.
In the case of pressurization, the viscous-flow material is passed through a die of a given shape and then, depending on the die, a continuous body of similar cross-section and die-like appearance. Followed by cooling and shaping to form a glassy state, thereby obtaining the desired processed parts.
