Overmold Tooling Design

The most common problems in overmolded cable assemblies center around overmolding approaches that limit the molding and assembly process parameters such that producing an acceptable range of parts is difficult. This is where the approach to overmold tooling design comes together. It is important to integrate the cable assembly process, tooling design and injection molding process. Too often, these functions are segregated and the end result is parts that do not work. The design of overmold tooling that facilitates interchangeable sections, and therefore modular molds, is often a great help in faster response to molding issues and lower tooling costs overall.

The familiar cry of "the molds don't work" often is the result of incomplete design of the overmold tooling relative to the cable assembly process, and utilizing a customer design that combines components, materials and processes that are inherently incompatible. Just as successful cable assemblies begin with good crimps, successful overmolded parts start with good mechanical stability between the components being molded. Once there is mechanical stability, the opportunity to focus on achieving optimum output from the design can be developed. Here, the combination of cavity design and part loading helps to determine the right configuration. Develop a multifaceted design team with a working knowledge of cable assembly and termination, overmold tooling design and injection molding processes. Approach the tooling equation from a less is better approach, and look at the total cost, including tooling, projected over the life of the part.
