Re: Overmolding/Insert molding
First off you should mold the abs and then over mold. Secondly you can purchase an add on injection unit from numerous companies now days. Most of them are available in all electric platforms for better repeatability, precision and costs savings. You can mount them in about any location you can imagine. Now you have flexibility for future work and can relocate the unit to other machines if designed that way.
Thirdly you should probably use a rotating plate either in the mold or machine. These too can be purchased from various suppliers. I wouldn’t recommend transfer over molding (robot moving them from one section of the mold to another) due to trying to hold the substrate in the EOAT and tool. Though you might could use core movement to make the parts, depending on the part geometry.

Re: Overmolding/Insert molding
Thank you all. We decided that with the relative low volume and our inexperience it would be better to outsource this component. It's one of many parts for an assembly. The assembly is the true value add with most all of our products. Our shoot and ship parts constitute less than 5% of our skews.
