Energy saving of extruder can be divided into two parts: one part is the driving force, one heating element.
Power saving: most inverters, energy-saving mode is by saving the energy consumption of the motor, for example, the actual power of the motor is 50Hz and you really only need 30Hz in production would have produced enough, that extra energy wasted, inverter is the effect of changing the power output of the motor to save energy.
Some energy-saving heating: heating and energy saving are using electromagnetic heating energy-saving, energy-saving rate is about 30%~70% the old resistance circle.
Plastic material from the hopper into the extruder, screw rotation, led by forward for conveying, materials in the process of moving forward, accept the barrel heats, screw shear and compression effect makes the material melting, resulting in glassy, high elastic and the variation of viscosity and flow of the Tri-State.
In a pressure situation, made in a viscous State of definite shape to the material through the die and then die and become a cross section and a similar continuum. And then cooling to form glassy, obtained the required processing of workpieces.
