There are various types of double-color(or multi-color)injection modling machine, which mainly diferentiates common injection molding machines in the design of injection unit and the movable mold plates. The mostly commonly-sed injection modling machines at present are double -clear-colr and blended-color types.

Double -Clear-color Injection Molding Machine

The double clear color injection molding machine consists of two injection units one univeral mold claamping unit and double color molds, which can manufacture plastic products with clearly marked color in the outer and inner layer. The technical process is:The first inejction unit begins to inject, cool, mold and open mold, still affixes the molded parts on the side of moving mold mold and moves it to the position for second molding. the fixed mold for second molding is provdied with space for first molding as well as the newly added space, after mold clampling, inject fused materials of the second color and take out the products after cooling and molding. The two injection units respeectively plasticate materials of different colors, the two cores are identical in shape and size, whereas dimensions of the cavities are different, to respectively mold the bottom and outer shape of products which is ultimately got through the conversion of mold revolving plate during production.
