How to reduce material waste and production costs when using PET injection molding machines?

1. Accurately control the amount of raw materials
In the PET injection molding process, material waste usually comes from excessive use of raw materials or unnecessary scraps. To solve this problem, accurate material ratio and use are the key. By introducing advanced screw design and precise injection control system, the amount of raw materials used for each injection can be effectively controlled to ensure that material waste is minimized without affecting product quality.

Servo control system: PET injection molding machines using servo control systems can accurately control the amount of raw materials for each injection according to the actual needs of the mold. The high-precision regulation of the servo motor can effectively avoid the injection of excess material and reduce unnecessary material waste.

Optimize mold design: Mold design has a vital impact on material utilization. By optimizing the runner design of the mold and reducing the volume of the gate and runner, material consumption can be reduced. The use of hot runner technology can avoid the generation of cold heads, thereby further reducing material waste.

2. Improve production efficiency and shorten production cycle
The improvement of production efficiency directly affects the reduction of material utilization and production costs. By optimizing the injection molding process parameters, adopting efficient production equipment and improving the production process, production efficiency can be significantly improved.

Efficient injection unit: The efficient injection unit design of the PET injection molding machine can shorten the injection molding cycle and improve production efficiency while ensuring product quality. The high-speed screw and injection assembly can quickly complete the plasticization and injection process, reduce the residence time of the material in the screw, and reduce the material waste caused by excessive plasticization.

Intelligent production management: By introducing an intelligent production management system, various parameters in the production process, such as temperature, pressure, speed, etc., can be monitored in real time, and the process parameters can be automatically adjusted according to the production situation to ensure the stability and consistency of the production process.

Mold replacement optimization: In the case of multi-product production, frequent mold replacement may cause material waste and time cost. The use of a quick-change mold system can significantly shorten the mold replacement time, reduce downtime and material loss.

3. Recycling waste materials and reducing raw material costs
The high recyclability of PET materials provides an important way for enterprises to reduce raw material costs. By establishing an effective waste recycling system, scraps and defective products generated during the production process can be reused to reduce dependence on raw materials.

Waste recycling system: Modern PET injection molding machines are usually equipped with waste recycling systems, which can recycle scraps and defective products generated during the production process for plasticization and injection molding again.

Online recycling and reuse: Recycling waste directly online and mixing it with new materials in proportion can reduce material waste while ensuring the stability of product quality. For PET materials, this recycling and reuse not only saves resources, but also meets the requirements of sustainable development.
