Two-color injection molding usually refers to the molding of two colors or different types of plastics. Since the two groups of injection units and nozzles of the two-color machine are independently separated, the colors of the finished products are mostly two distinct colors, and they are not mixed together.liquid silicone products
The biggest difference between the two-color injection molding machine and the general injection molding machine is the design of the movable template of the injection unit machine. Generally speaking, a two-color machine has two independent injection units, while a general injection machine has only one injection unit.
The configuration of the two-color injection unit varies according to the design of each manufacturer. As for the design of the movable template, a rotating mechanism needs to be provided. Common designs such as adding a turntable or a rotating shaft mechanism provide a 180° reciprocating rotation function to make the mold produce cyclical alternating movements. For some special two-color molds, there is no need for a turntable or shaft mechanism, and the mold slides alternately or rotates horizontally.
