Product Description

With the growth of bottle packaging market and relatively stable global market, the market demand for PET bottle preform making machine is still large. Therefore, we have sorted out some basic knowledge about PET bottle preform making machine. If you just want to invest in the bottle embryo project, but you don't know about the selection of PET bottle preform making machine, I hope you can gain something after reading it.


PET bottle preform making machine


There is a core principle when selecting PET bottle preform making machine - to improve the production efficiency of bottle embryo and reduce the energy consumption of the machine. We can learn from four aspects.


PET bottle preform making machine


1. Injection unit

- temperature control section

Since the melting point of PET material is as high as 255 ℃, but the stabilization time is short when it is higher than the melting point, it is very important to control the temperature well, which will require more barrel temperature control parts. The temperature of the special PET bottle preform making machine produced by ZOWEITE company is controlled by the PID algorithm module with high precision and high response to ensure the high-precision injection quality.

- Injection speed

Generally, the faster the injection speed, the higher the quality of the preform. However, it is still necessary to pay attention to the shear rate when filling at high speed, because higher shear rate will make the preform brittle.

2. Mode locking unit

- mold opening and closing stroke

- clamping force

The maximum number of cavities (e.g. 72 to 144) depends on both of them (including injection pressure). Therefore, you can compare these specifications on different injection molding machines to find a more suitable machine.

- stable clamping speed

If the mold opening and closing of the machine is faster and more stable, the drying cycle of bottle embryo can be reduced and the production efficiency of bottle embryo can be improved.

3. Drive unit

Advanced drive unit design can greatly reduce energy consumption. It may include servo motor, oil pump, air blowing valve, oil discharge and other devices.

4. Maintenance

The longer the shutdown time of the PET bottle preform making machine, the greater the loss of the factory. Therefore, simple maintenance of the injection molding machine can not only save maintenance time, but also help the machine to run for a long time without unnecessary shutdown.

If you want to know more about PET bottle preform making machine or buy injection molding machine, please contact us. The models of bottle embryo injection molding machine produced by ZOWEITE company range from 200ton to 400ton, which can fully meet the needs of the market.
