Morgan Plastic Molding

Since 1968 Morgan Plastic has made handy little presses for engineers and small manufacturers. See: http://www.morganindustriesinc.com/ You can buy them on the used market for little money. For years we used parts from these presses when large production was impossible.

Great story, Ann. I really like the slideshow. Better quality parts than 3D printing and lower cost -- what's not to like?

Yes, JimT, I remember both of those presses. At my local zoo, I believe they made plastic hippos. I also remember the coin press.

Thanks, Al. This made me think of a Gadget Freak article in reverse: what would happen if one of our many innovative, creative Gadget Freak inventors had gone ahead and commercialized his/her invention and sold it? I've noticed reader requests for exactly that on some Gadget Freak comment boards.

Excellent slide show, and a good example of engineers as opportunists.  Developing a way to cost effectively create custom parts.

Yes, I remember those kits as a kid, Jim. I had one that made plastic (or some similar material) army men.

Do you remember when you were a kid; there were two examples of modern industry at the Zoo? One was the little coining press that took your copper penny and rolled it into a coined medallion; the other was micro injection press that molded a little bear as a souvenir in front of the Polar Bear house. For a Quarter, you watched a little mold-press produce your bear.  I still remember the smell of molten polycarbonate I smelled for the very first time.
