Description

Technical Field

[0001] The invention relates to the technical field related to injection molds, and in particular to a double-material horizontally-shot rotary mold. Background Art

[0002] Two-color injection molding refers to the process of injecting two different materials into the same mold, so that the molded parts are formed by two materials. Some of the two materials are different colors, and some are different in hardness and softness, thereby improving the plastic appearance and assembly performance of the product. Two-color injection molding of automotive parts has high product quality stability, and product deformation is easy to control. Two-color mold injection molding has become a trend in the field of automotive parts.
