Two-color injection molding is a precision process that involves injecting two different colors or types of materials sequentially or simultaneously into the same mold using a specialized injection molding machine to form a single integrated component. This process typically employs a rotating mold, where after the first injection molding cycle, the mold rotates 180 degrees for the second injection, ensuring a strong bond between the two materials. It not only achieves a perfect combination of dual colors or multiple materials (such as soft and hard plastics) but also significantly enhances the product's aesthetics, tactile feel, and functionality. It is widely used in industries such as electronics, automotive, and medical fields.
