2K Over-Moulding Mold

Two-color mold（2Kmold）: Two kinds of plastic materials are injection-molded on the same injection molding machine, and molded in two parts, but the product only molds once. Generally, this molding process is also called double-material injection molding, usually completed by one set of molds, and requires a special two-color injection molding machine.
Over-molding mold: Two kinds of plastic materials are not necessarily injection molded on the same injection molding machine, and are molded in two parts; after the product is taken out from a set of molds, it is placed in another set of molds for the second injection molding. Therefore, in general, this molding process is usually completed by two sets of molds, without the need for a special two-color injection molding machine.
