1. A process for producing an insert molded part comprising the steps of:

  • providing a glass lens;

    providing a front housing unit;

    providing a thermobond adhesive;

    applying thermobond adhesive onto the glass lens;

    inserting the glass lens into the front housing unit, aligning the glass lens with the front housing unit such that the glass lens lies within the inside of the front housing unit;

    injecting a molten resin, during an insert molding process, into space formed by the glass lens and the front housing unit;

    wherein the molten resin flows around the glass lens, the molten resin activates and liquefies the thermobond adhesive that is applied onto the glass lens and forms an insert molded part, and when the insert molded part is ejected and cooled, the thermobond adhesive permanently bonds the glass lens and the molten resin.
