Dalian film blowing unit clear their product packaging grades, the materials of their products, and then select the machine configuration, buy the machine and buy a car is the same reason, a sub penny goods, Dalian PE film blowing machine manufacturers that you want to clear their own products and then choose a film blowing machine. One is the power part, one is the heating part. Dynamic part of energy-saving: most of the inverter, energy-saving way is through the residual energy saving motor, such as the real power of the motor is 50Hz, and you in production really only need to 30Hz is sufficient to produce, the superfluous energy is wasted, the frequency converter is to change the output power of the motor to achieve energy-saving effect. Heating part of the energy saving: the heating part of the energy saving is mostly used electromagnetic heater, energy saving rate is about 30%-70%. In the process of pushing forward the plastic particles, the friction between the plastic and the screw, the plastic and the cylinder, and the collision between the particles and the friction between the particles, but also due to the external heating and gradually melting.
