How to make film blowing machine more energy efficient

Speaking of energy-saving film blowing machine, mainly from the power section and the heating section. In the power section, they use the drive, energy is through energy savings over the motor, such as the actual power of the motor is 50Hz, 30Hz and you really only need enough production in the production, those extra energy in vain wasted, the inverter is to change the power output of the motor to achieve the energy saving effect; most heated part of the electromagnetic heater energy efficiency, energy-saving rate is about 30% -70% of the old-fashioned resistance circle.
