Method of making a crosslinked overmolded assembly

A process for making a crosslinked assembly comprising the steps of:

• selecting a desired performance parameter for a molded assembly including a first polymeric component of a first thermoplastic material having a first component wall thickness and a first connection portion, and a second polymeric component of a second thermoplastic material having a second component wall thickness and a second connection portion bonded to the first connection portion,
• controlling a first crosslinking percentage for the first polymeric component and a second crosslinking percentage for the second polymeric component independently to provide the desired performance parameter for the assembly,
• orienting the assembly at an angle (A) between an orientation axis of the assembly and an electron beam direction,
• exposing the oriented assembly a number of times (N) to an electron beam operable to deliver a predetermined amount of radiation (R) in the electron beam direction,
• providing a total radiation exposure (E) proportional to (N×R) providing the first component crosslinking percentage and the second component crosslinking percentage, the crosslinked assembly having the desired performance parameter.
