This video is a live production recording of the CMS170 two-shot injection molding machine from Ningbo Konger Machinery Co., Ltd., fully demonstrating the two-color gradient injection molding process for PET preforms.
The Konger CMS series injection molding machine features an innovative horizontal twin injection unit design, which can inject two different colors of PET material simultaneously. With precise control over material flow and cooling cycles, it produces two-color gradient PET preforms with smooth color transitions and no obvious layering.
This process not only meets the strict hygiene and strength requirements for food packaging, but also upgrades packaging appearance from single color to gradient aesthetics. It is widely suitable for high-end packaging applications such as mineral water bottles, beverage bottles, and daily chemical bottles.
In this application, the CMS170 two-shot injection molding machine achieves outstanding performance thanks to its stable clamping force, efficient plasticizing system, and precise injection control:
Uniform blending of two-color materials, delivering delicate and natural gradient effects
Consistent wall thickness of PET preforms, free of burrs and bubbles
Stable production cycle, ideal for mass production
Complies with food contact material safety standards, ready for food packaging applications
As a professional manufacturer of two-color injection molding machines based in Ningbo, Ningbo Konger Machinery is committed to the R&D and innovation of injection molding equipment.
The CMS series two-shot injection molding machine is not only used for PET preform production, but also adaptable to two-color / multi-color injection molding in cosmetics packaging, toys, daily necessities and other fields, providing enterprises with efficient and aesthetic production solutions.
