    you can use collapsible core if you can tolerate small parting lines inside of your shape.
    Be careful about patents, this things are usually under some patent pending.

    Re: Overmolding or insert molding?

    Hi,
    the issue is in the material used.
    Try to think about some filler - like glass fiber for example.
    There is no need to make any other correction in the tool or process.
    Let us know.
