PET injection molding solutions

The packaging bottles commonly used in daily chemical products are mainly made of PET material. This material has high viscosity and is sensitive to temperature. Improper temperature can easily cause poor product permeability and uneven wall thickness, resulting in waste of raw materials and increased production costs. If the preform is not suitable during injection molding, only a slight external force can cause the bottleneck or bottle mouth to break. Given the molding difficulties of PET raw materials, Topstar provides PET-specific plastic injection molding machine, which use special screws, high-torque motors, and increased power systems to improve the overall plasticization efficiency by more than 20%. At the same time, it also dramatically reduces the defects such as bubbles and impurities that may occur during the molding process, ensuring the permeability and yield rate of the molded preforms.

Demand for plastic injection molding machine for PET materials

The high viscosity characteristics of PET require specific molding solutions to maintain optimal production quality and efficiency. Generally speaking, traditional plastic injection molding machines may find it difficult to cope with the challenges brought by PET materials. They are prone to bubbles, impurities, or insufficient plasticization, which may cause defects in molded parts.

The plastic injection molding machine designed for PET materials provided by Topstar uses a dedicated screw, a high-torque motor, and a power system. All these functions work together to increase plasticizing efficiency by more than 20%. While ensuring product quality, Topstar also meets the needs of improving production efficiency and saving costs. Based on the integrated design concept of the injection molding process, the PET-specific plastic injection molding machine has a self-developed control system that supports the host-linked robot signal, the host-linked peripheral auxiliary pressure, temperature, and other key process parameters to improve production efficiency. In addition, the machine uses an infrared heating coil to save energy by about 20%, enhance thermal energy conversion efficiency, and reduce energy consumption during production.

The plastic injection molding machine uses a dedicated screw to optimize PET material processing.

PET is a semi-crystalline material that requires precise control of its heating and cooling process to avoid problems such as uneven crystallization or bubbles. Topstar’s dedicated screw design improves the melting and mixing of PET materials, ensuring that the resin is evenly distributed and thoroughly heated. This produces a higher quality melt, essential for producing preforms with excellent transparency and strength. At the same time, the design of the screw optimizes the mixing zone to ensure the resin evenly distributes, allowing the PET material to mix and homogenize thoroughly before injection. Any inconsistency in the melt will cause changes in the mechanical properties of the final product, so this suitable mixing is essential. The high-quality melt produced by the dedicated screw can ensure that the preform molded parts have excellent optical properties and excellent structural integrity. This improves the durability of the final product.

High-torque motors are used to increase the power system.

The high-torque motor used in the plastic injection molding machine specially built for PET increases the entire power system and improves the plasticization efficiency by more than 20%. Enable the system to melt and mix plastic resins faster and more efficiently. Unlike traditional motors, high-torque motors bring greater force and stability. This can shorten processing time and make it heat more evenly, ensuring that the plastic material reaches the required temperature and consistency in a shorter time. At the same time, it dramatically reduces defects such as bubbles and impurities that may occur during the molding process, ensuring the permeability and yield of the molded preforms. High-torque motors ensure more thorough and consistent plasticization, minimizing the risk of trapped air and contamination.

Improve production efficiency and save costs

The PET-specific plastic injection molding machine adopts the integrated injection molding process design concept. It is based on a self-developed control system and can support the host linkage robot signal. The host can adjust the key process parameters, such as the pressure and temperature of the peripheral auxiliary machines, to improve production efficiency. It can ensure that all injection molding equipment works in coordination to achieve the best production conditions. This integration can minimize downtime, reduce variability, and improve the overall efficiency of the production line.

The machine features an infrared heating coil that improves heat energy conversion efficiency and reduces energy consumption during production. Calculations show that the infrared heating coil saves energy by about 20%. Using infrared technology, the heating coil can directly heat the PET material more effectively than traditional methods, ensuring faster and more uniform heating of the entire molding area.

Open up blow molding automation

After the injection molding process is completed, the preform will enter the following key process: molding to form the final product. Based on software control capabilities, Topstar can open up the blow molding automation of the back end of injection molding. After the injection molding process shapes the PET raw materials, the conveyor belt smoothly carries the preforms into the blow molding process, optimizing manpower allocation and maximizing production efficiency. Such system design ensures the entire production line’s smooth and efficient production process.

By automating the transfer and handling steps between these two key stages, Topstar eliminates the need for manual handling and intervention. This speeds up the production process and ensures that each preform moves smoothly from one stage to the next without delays or bottlenecks. The automated system reduces human errors, improves precision, optimizes production throughput, and dramatically improves the overall efficiency of the production line.
