When the blow molding machine is started, the current of the motor will be 5-6 times higher than the rated value, which will not only affect the service life of the motor but also consume more power. The system will leave a certain margin on the motor selection during design. The speed of the motor is fixed, but in actual use, sometimes it is necessary to run at a lower or higher speed, so it is very necessary to carry out frequency conversion. The frequency converter can realize the soft start of the motor, achieve the purpose of energy saving and speed regulation by changing the input voltage frequency of the equipment, and can provide protection functions such as overcurrent, overvoltage and overload to the equipment. Our company introduces foreign advanced technology and has established a research and development team with many experts, engineers and technicians to ensure the excellent quality of the products.

The two-step blow molding enables the main blow molding machine to be fed in succession, where the hopper exerts the effect of the bumper. The optimization of the entire production process by the feeding of this method is of great significance because those operators do not have to operate the blow molding machine discontinuously and then make it busy with other operations.
Pre-blown particles are now excellently added to the NZ-type secondary blow molding machine after being controlled by an inter-stop switch. The placement of the two blow molding machines can be selected one above the other or one after the other. The secondary blow molding machine operates on the principle of the cutting machine and is designed for pre-blown particles. Compared to general blow molding machines, the second-generation blow molding machines are much smaller in size and require only a small amount of machine drive energy. Because of its uniform feeding, it worked at a speed of approximately 450 min-1, and there was no problem. When such a blow molding machine is used for the second destruction of pre-blowing data, the noise level of the attack is much lower than that of the one-speed processing (n=450-500 min-1).
