New Kind Of Glue

Same idea, different take

Pretty much any polymer based material will shrink when heated, but not all will stay shrunk. Back when I was selling packaging materials, ie shrink and other films, my manager and I one day when bored tried shrinking every type of film that we had, and they all shrunk. A few of them loosened over time.

This looks interesting. If someone tries it, report back on your results!

Spent a summer working in a plastic blow molding factory. We had wooden dowels, when the plastic bottles stuck in the mold we used the dowel to pry them out before the molds snapped shut for the next cycle. High tech stuff. The machines extruded a hollow hot plastic tube that the molds snapped shut on and blew up in the bottle shaped mold. When guys got bored they would stick the dowels in the hot plastic, spin it and make odd shaped handles, whatever that stuck to the dowel. We made bottles for baby wipes. I would imagine any bottle with enough heat applied would go back to a plastic goo. We took the reject bottles, ground them which was fed back to the plastic machine for reuse. So the plastic is reusable. RJF

I spent 12 years in a injection mold factory.. we made shopping cart baskets.. and hand held baskets milk crates etc.. Your story of the wood dowels digging the item out of the mold reminded me of us having to do that...  We used metal rod with a handle and a hook on the end of it to dig them loose... had to be quick at it or you'd be shut in the door... Had to be good with all the work crew  because the coworker on your line had to stand by the kill switch, LOL... If only OSHA knew they was having us do that when the push pins on the mold stopped working but they needed to get the order out the door before they could shut it down.. 

Thankfully I never run the machines much as I was a fork lift driver..

When I worked factories, I wondered if OSHA did anything. When the plastic bottles came off the blow molding machine they were blown up a wire cage system to the ceiling of the factory. The cage arched and fed a trimmer that cut the top off. Many times the bottles stuck at the top of the cage. One guy would always step of each fork of the fork lift and was lifted up to pull the bottles apart. Did this the whole summer I worked there. Heard he fell from the top and hit the concrete floor and is a quadriplegic. Not once was he stopped or did they think maybe this wasn't smart. RJF

Well now you have a retirement income so selling tools at a BIG DISCOUNT to us POOR village folks would be a little pickup money for you.  😀 RJF

Well, I still have many of my old contacts but most of it was for mechanical tools. BUT, my son is now in the business up in Colorado Springs. So, I guess I still have my foot in it vicariously. If you know anybody who wants to by their own boss, tell them to PM me. It's a great way to make a living and call your own shots. I highly recommend it.
