What are the Essential Features of PET Preform Injection Molding Machine ?
Preforms are made from Polyethylene Terephthalate (PET), which are also called PET preforms. PET preforms normally manufactured by using a mold on an injection molding system, which is subsequently blown into a container for edible or non-edible liquids (water, soft drinks, alcohol, oils, personal care) on a blow molding system. They are intermediate product in the production chain, and as they can be easily blown into the shape of the final container, they can vary in weight, color and shape.
The PET preform injection molding machine is an integral part of the PET preform manufacturing process. Its precision and accuracy ensure that the final products meet the desired specifications and are suitable for various applications. Manufacturers can rely on the PET preform injection molding machine to produce high-quality preforms that can be easily blown into final container shapes. This maks it an efficient and cost-effective solution for the production of plastic containers.
In this article, we are going to introduce some essential features of PET preforms injection molding machines that help you improve efficiency and productivity.

1. Double-circuit system/ separate injection and plasticization：
For manufacturing products that need high-speed injection, such as PET preform, using injection molding machine with the double-circuit system or separate injection and plasticization would be more efficient. The double-circuit system, through performing material loading and mold clamping simultaneously, can stabilize the material plasticizing. Moreover, with an electrical charging system, it can improve the stability of the machine and shorten the cycle time then reaches great productivity.
On the other hand, the separate injection and plasticization is suitable for bigger productivity and shorter cycle time. Characteristics being injection separate from plasticizing unit, resin into plasticizing unit through electrical charging reaching stable plasticizing effect. The plasticized material is then conveyed to the bottom plunger for injection and pressure holding. This system allows charging on fly to injection and pressure holding, with the aid of 3 stations outside the cooling system will greatly reduce the cycle time.

2. Hybrid plastic injection molding：
Compared to hydraulic and electrical, the hybrid plastic injection molding machine would be a better choice. Considering its high-speed, the hydraulic parts provide more power. With electrical mold clamping, the mold opening position is more accurate. Therefore, the production line would not be stocked by troubleshooting.

3.The full solution of PET injection molding：
Normally, the manufacturer who wants to produce PET preforms, needs not only the injection molding machine but also the related equipment to help to build a whole production line. CLF integrated the entire equipment including injection molding machine, mold, robot, dehumidifying and resin conveying system, mold dehumidifier and chiller. From starting, test run, to production, enable customers to reach production targets quicker and easier. Moreover, for product mold under 48 cavity, CLF provide designed twin cylinder injection and electrical screw charging injection unit, available with options in preform auto drop 3 stations outside cooling system for the user's choice.

The success of PET preform injection molding machines lies in their high precision and efficiency, making them ideal for large-scale production. With advanced control systems and energy-saving designs, these machines not only reduce energy consumption but also ensure stable production processes. While understanding the technical features of the machine is crucial, it's equally important to be prepared for potential process issues. If you encounter defects like deformation or bubbles during production, refer to our PET Preform Injection Molding Troubleshooting Guide to enhance efficiency and reduce reject rates.
