We have rich experience with overmolding,first of all. Let me introduce what is overmolding process: Two-shot or multi-shot molds are designed to “overmold” within a single molding cycle and must be processed on specialized injection molding machines with two or more injection units. This process is actually an injection molding process performed twice. In the first step, the base color material is molded into a basic shape. Then the second material is injection-molded into the remaining open spaces. That space is then filled during the second injection step with a material of a different color.
Overmolding process require more precision machining and high skilled tool makers,and the cost is little bit higher than normal molds, and it need two molds, please see the mold cost breakdown for Sucker Handle as below:
