This equipment can mold parts that are larger than itself.

Wouldn't it be more accurate to say that it can pump enough molten plastic to make parts larger than itself?
I'm assuming that if you add all the components required to make a part bigger than that equipment it's total volume and footprint will extend quite significantly?

I don't think plastics has a place on a machinist forum.

When I was working in the machine shop of the company that employed me we turned a LOT of plastic. Big plastic bearings. I'm talking 9" OD x 8" ID x 18' long.

Our largest current diameter is 8" x 24 long solid injection molded plastic. However, we can make larger parts without difficulty. Just so far didn't have any demand for larger diameter solid rods.

Yes I was machining plastic parts for textile plants in the mid 70’s. In fact here locally there is a shop that machines plastic exclusively. I have a lot of Delrin UMHW in my material pile. Most is old fixtures that came from Eaton that I picked up before retirement.

I just got sent a Quill wheel to take the place of an handle on my Lagun by Jim Enos. The hub that the wheel is mounted to is UMHW. I had to machine a spacer to move the wheel out away form the quill feed clutch engagement lever. I machined it up out of Delrin that I repurposed.

I posted a video to my channel. I machined a lot of things out of rectangular stock

That looks like my home shop turning rectangular stock round on an arbor. I used to make hubs for tire treatment stands for kart racers just that way. In fact I recently made some hubs if for a friend.
