I’ve been playing around a lot with plastic bags and I like how workable they are in just about every aspect, but I’ve also been wanting to figure out a low cost low volume injection machine.

The flower trinket was made by making solid sticks out of bags and melting it into the mold with a sodering iron. I don’t recommend that method at all unless you have one with a temp control. Too hot and too many fumes. But I kinda liked the results. I layered the colors in reverse and worked my way up. It took a very long time and isn’t feasible.

The circular trinket was made much faster and came out great. I modified a high temp hot glue gun by removing the ball bearing anti drip mechanism in the tip and drilling the hole out slightly. I made sticks by stuffing bags in to a brass tube and melting it down in the oven and then compacting. It comes out with gaps but this is fixed in the heating chamber of the glue gun and isn’t an issue. It’s an 80w gun with dual heaters and it gets hot enough to flow out on its own. I load the stick and when it gets too short I insert a wood dowel behind it to keep the guns push mechanism working. As it goes in to the open face mold, I press it flat with a small screwdriver to hold it as I move the gun. The plastic doesn’t stick to the silicone and tried to warp immediately. I’m happy with the results and then should be good enough for small injections, perhaps larger with a heated mold.

A short stay in the oven with a glass weight on top makes the details pop more and leaves a shiny smooth finish on the back.
Here’s also a pic of the original attempt with the flower.

I was having trouble with this post for some reason. I’ll attempt to load a few others.

The molds are just simple off the shelf one piece molds from a craft store. I just wanted to prove the concept. I thought at first that they would be too flexible but they worked just fine. The trick was being able to inject the plastic in to it. I tried the same thing using a mass of plastic and weight, but the results weren’t even close. Especially the marbeling.

@greasemonkey0341, it seems that the photo upload had some sort of an error, could you please re-upload the photo?
