One. Two-color injection molding advantages:
Two-color molds can use two different characteristics of the resin and color as a single two-color product, can reduce the assembly of the molding and post-processing projects. It saves the cost of melting and printing, increases the aesthetic appearance of the product, and enhances the grade and added value of the product. Not only has the function of anti-slip, increase friction, flexible resin material makes it more ergonomic, feel better. Two-color injection molding products of high quality and stability, easy to control the deformation of the product, the molding cycle of a short production, the loss of 7% lower than the plastic injection molding, product manufacturing costs can be lower than the plastic coating 20% -30%.
Two. Two-color molding principle
Two-color injection molding usually refers to the molding of two colors or different types of plastics. Since the two sets of injection units and the nozzles of the two-color machine are separated independently, the color of the finished product is mostly bicolor and not mixed together. The biggest difference between a two-color injection molding machine and a general injection molding machine is the design of the ejector unit motion template. In general, a two-color machine has two separate injection units, whereas a typical injection engine has only one injection unit. The configuration of the two injection units of the two groups is in various forms with the design of each manufacturer. As for the design of the movable formwork, a rotation mechanism must be provided. Generally, common designs such as adding a turntable or a rotating shaft mechanism provide 180° reciprocation. Rotation function, so that the mold produces a cycle of alternating action.
