What is the working principle of a dual color injection molding machine? How does it achieve injection of two colors?

The dual color Injection Molding Machine is a special injection molding equipment that can inject two different colored plastic materials into the same product, bringing rich visual effects and design possibilities to the product. So, what is the working principle of a dual color injection molding machine? How does it achieve injection of two colors? The manufacturer of Liansheng Small Injection Molding Machine will provide a detailed analysis of this.plastic household mold.






The working principle of a dual color injection molding machine mainly includes the following steps:



1. Injection device: Dual color injection molding machines are usually equipped with two independent injection devices, each used to inject plastic materials of different colors. Each injection device includes a feeding hopper, a screw, and a heating ring. By controlling the rotation of the screw and the heating of the heating ring, the plastic material is heated and melted, and injected into the mold under a certain pressure.Precision Core Parts.



2. Mold design: The mold design of a dual color injection molding machine is crucial, as it requires two or more injection chambers and color matching channels. Each injection chamber corresponds to an injection device, which controls the opening and closing states of different injection chambers and color matching channels to achieve injection of different colors.Servo Type Injection Molding Machine.



3. Injection process: During the injection process, one color of plastic material is first heated and melted and injected into one injection chamber, while the other injection chamber remains closed. After the injection of the first color is completed, the injection chamber switches to a plastic material of another color and injects it into another injection chamber.



4. Injection process: During the injection process, two colors of injection cavities in the mold are simultaneously injected into the molding cavity of the product. Due to the reasonable design of the shape and position of the injection cavity and the molding cavity, two colors of plastic materials can be filled alternately in the molding cavity, achieving a dual color effect of the product.



Through the above working principles, the dual color injection molding machine can accurately control the injection ratio and position of two colors to achieve different color effects and pattern designs. This provides greater flexibility for the appearance and personalization of the product.



The dual color injection molding machine has a wide range of applications, especially suitable for fields that require multi-color or multi material combinations such as automotive components, household appliances, and electronic equipment casings. It not only provides a more attractive and personalized product appearance, but also reduces assembly processes and improves production efficiency.

In summary, the dual color injection molding machine achieves the injection of two different colored plastic materials into the same product through its unique working principle and mold design. Its working principle is clear and concise, which can bring rich and diverse appearance effects to the product, providing manufacturers with more design and production options.
