Aluminum mold test on DIY desktop injection machine

In this video I'll test the aluminum injection mold made on my DIY CNC machine with my DIY manual desktop plastic injection machine.

I think you did a good job. As far as it being tight for the bolt head. What I would do is to cut a few groves into the bolt head with a hacksaw, to give some channels for the plastic to grip onto the head. Then I would heat the bolt head hot enough so it can partially melt the plastic. Then press the head into the plastic. I would try this on the first print to see how it goes before trying it on the better part.
I had tried to do some plastic molding. I did not have a mold machine. The mold I made was for a dome for a light sensor. It was 50mm in diameter. I had virgin ground plastic that I placed in the mold then heated the mold in a toaster oven. When hot enough I pulled it out and put it on a drill press table and I used the chuck to press down on the top of the mold. I had a couple of holes in the mold that allowed the excess plastic to flow out. I held it until it was cool enough (but still hot) to remove the part. Pulling it off before it cooled completely allowed for easier extraction.
I worked as an electronic designer and this was what I did to get some prototype parts. I'm retired now so I'm only working on hobby projects.

That depends on what CAD software you plan to use to make the mold.
