Two-color mold: a mold in which two plastic materials are injected on the same injection molding machine and molded in two times, but the product is only released once. Generally, this molding process is also called two-component injection molding, which is usually completed by a set of molds and requires a special two-color injection molding machine. Two-color molds are becoming more and more popular in the market. This process can make the appearance of the product more beautiful, and it is easy to change colors without spraying, but the cost is expensive and the technical requirements are high.
