The two-color injection molding machine is a special injection molding equipment, which can inject two different colors of plastic materials into the same product, bringing rich appearance effects and design possibilities to the product. So, how does the two-color injection molding machine work? How does it achieve two color injection? Lian Sheng Small injection molding machine The manufacturer will analyze this in detail.
The working principle of the two-color injection molding machine mainly includes the following steps:
1. Injection device: The two-color injection molding machine is usually equipped with two independent injection devices, which are respectively 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.
2. Mold design: The mold design of the two-color injection molding machine is very critical. It needs two or more injection cavities and color matching channels. Each injection chamber corresponds to an injection device, which can realize injection of different colors by controlling the opening and closing states of different injection chambers and color matching channels.
3. Injection process: during the injection process, first heat and melt the plastic material of one color and inject it into an injection chamber, while the other injection chamber remains closed. When 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: in the injection process, the injection cavities of two colors 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, the plastic materials of two colors can be alternately filled in the molding cavity, thus realizing the two-color effect of the product.
Through the above working principle, the two-color injection molding machine can accurately control the injection proportion and position of two colors to achieve different color effects and pattern design. This provides greater flexibility for the appearance and personalization of products.
The two-color injection molding machine is widely used, especially in the fields that need multi-color or multi material combination, such as auto parts, household appliances, electronic equipment shells, etc. It can not only provide a more attractive and personalized product appearance, but also reduce assembly processes and improve production efficiency.
to make a long story short, Two color injection molding machine Through the unique working principle and mold design, it is realized to inject two different colors of plastic materials into the same product. Its working principle is clear and simple, which can bring a variety of appearance effects for products and provide manufacturers with more design and production options.
