PET Injection Molding Machine: How to achieve 20% to 80% energy saving?

1. Dynamic power regulation
One of the core advantages of PET injection molding machine is its dynamic power regulation function. During the operation of traditional injection molding machines, the power output is usually maintained at a fixed level regardless of the actual load, which leads to a lot of energy waste. The PET injection molding machine adopts an advanced servo motor system to adjust the output power in real time according to the change of load. In the pressure holding stage, when the material flows slowly, the servo motor automatically reduces the speed to reduce energy consumption.

2. Zero power consumption cooling
During the cooling stage, the PET injection molding machine realizes the design concept of zero power consumption. When the machine is in a cooling state, the servo motor stops working completely, thus consuming zero electricity. This design not only optimizes the energy consumption structure, but also improves the overall efficiency of the equipment. Compared with traditional injection molding machines, PET injection molding machines do not consume any electricity at all during the non-production stage, which greatly reduces energy consumption.

3. Accurate closed-loop control system
To ensure energy efficiency and product quality, the PET injection molding machine is equipped with accurate pressure sensors and rotary encoders. These sensors monitor flow and pressure in real time and feed the data back to the control system. Based on the feedback information, the servo motor automatically adjusts the flow and pressure, and ensures that the machine operates in the best condition by changing the speed and torque. This closed-loop control system not only improves energy efficiency, but also ensures product consistency and stability.

4. Optimized screw and injection unit design
The PET injection molding machine uses a specially designed screw and injection unit to optimize the plasticization and molding process of PET raw materials. This design can improve the plasticization efficiency of the material and reduce energy consumption. In traditional injection molding machines, the material often requires a higher energy input during the plasticization process, while the PET injection molding machine can achieve higher plasticization efficiency through its unique screw design, thereby further reducing energy consumption.

5. Highly responsive drive system
The drive system of the PET injection molding machine is highly sensitive and can respond to load changes in a very short time (only 0.05 seconds). This fast response capability not only improves production efficiency, but also significantly shortens the cycle time. In each production cycle, the time and energy saved will eventually be converted into considerable economic benefits.

6. Adaptable mold installation design
The PET injection molding machine has a larger mold installation space and a longer mold opening stroke, allowing it to accommodate larger molds for production. This flexibility enables the machine to handle complex product designs without the need for frequent equipment changes, further saving production costs and time.
