How To Mold HDPE Plastic To Make Parts! Trash to Treasure, Part 3? From a Creepy Crawler Mold?

[@rx0788]

Roll it into a stick and use a glue gun to inject it into the mould but thats me being silly

[@1D10CRACY]

I did a video like this a few months ago with not much success.... kzbin.info/www/bejne/gImcdGerrNF0d8U

@@1D10CRACY Thanks for trying! :)

[@TheRedstonelabz1]

After you cut out the mickey you basically have the right volume for the mould. If you place it back in the over with the mickey in the mould and clamp it down after you take it out you probably have a perfect part with verry little cleanup afterwards.

[@shinyshinythings]

80s and 90s? I remember creepy crawlers from the late 60s/early 70s! The “strange change machine” was the best toy ever.

[@anaphylaxis2548]

I was going to comment the same thing. I guess he’s a lot younger than I am. LOL

[@bh-ps6ex]

Maybe if you melted the hdpe directly in the the mold you would get the casting your looking for

[@ollie-d]

I had the same thought. If the HDPE can get proper liquified in the mold the results should be great

[@dlindeman]

With a heat gun you could turn the feet forward post molding so the figure would stand . Great video!

[@tedspens]

Creepy Crawlers was the coolest! 😁

[@hansdegroot8549]

I like this very much. Thanks for sharing. I was surprised that in the end you put the whole under (cold) water to have it cooled down quicker. It's often said that HDPE shrinks a lot when in cools down freely and therefore it is recommended to have your molded part clamped and have it all cooled down really slowly.

[@TheFishingHobby]

Just subscribed to your channel, good stuff. Milk jug HDPE doesn't flow as well as some other the other types for whatever reason. The HDPE plastic buckets seems to be a little softer when heated and more fluid. They would probably work better in a mold. Also, LDPE is often used on food container lids and other things. It is marked with a number 4 in the recycling symbol. It really flows well but isn't quite as hard. For something like this, that probably wouldn't matter. Nice work!

[@IBFinchie]

Could you place the mold in the pan and lay the HDPE on top and then place in oven all together. As it heats it will conform to mold. And as for the different colors you could lay strips in first to color shirt and shoes, ears and so on? Try it and post the results. You have some good stuff. Thanks

[@ss9c1]

I would have tossed it back in the oven after the mold was filled, then used a flat plate and press the 2 parts together

[@hansdegroot8549]

I would have done exactly the same.

[@artchan126]

Consider....putting Mickey in a metal tin....place finer cut pieces of milk plastic into a metal cup and melt in oven ..when clear ..open door while in oven using tongs or pliers pour cup into mould to surface level of. Mickey plate without excess...any slight excess.. use metal spatula or equivalent to swipe flush of on surface if heated too

[@fullstrutn]

you've given me a great idea or way to fix my kayak to fill a large hole

[@20greeneyes20]

I guess you can use old crayons melt them and pour. I bought a bunch of the creepy crawler molds I'm going to try to use crayons I got from Goodwill. Should spray the molds with stray cooking oil so they won't get stuck in the molds. What do t's think ?

[@chalkline1505]

put the mold on a hot plate and grind up the plastic into finer pieces. just a thought

[@travissmith7471]

Thanks for sharing... It was very informative...

[@steelforbrains]

If you heat HDPE up hotter, is it pourable? I would like to pour some into a two part mold. Maybe use a glass dish instead of a metal pan, so that it retains heat better.

[@TheEpicSpire]

no. after it gets too hot it will begin to burn. I have never been able to get it pour-able. If im wrong, i'm willing to learn how.

[@veratek1]

@@TheEpicSpire it would be nice to get an explanation from a chemist as to why that happens. maybe there is some sort of substance that could be mixed to the HDPE to make it become more liquid when heated? it seems a bit odd that it goes from thick goo to burning without an in-between state. this is a key question in my opinion, since it would open up the door to a million possibilities for small-scale recycling

[@TheEpicSpire]

@@veratek1 from what i understand, there are two types of plastic. Thermoplastic materials can be cooled and heated several times without any change in their chemistry or mechanical properties. then there is Thermoset, which the heat will effectively cure the plastic, like putting clay in oven. it is set and will only burn if you heat it again. HDPE is a thermoplastic, but once you heat it above it's setting point, or bake the plastic too long it will set. This happens to all Thermoplastics after a specific heat point. However, there may be a way to do so if you treat the HDPE in a Sous Vide style setup. Set the water bath to the proper temperature to soften the HDPE and then leave it in there for a few hours, allowing the sous vide to regulate the temperature. but the HDPE will most likely cool off too fast and will begin to thicken back up after you take it out. it would just be easier to grind the HDPE into tiny dust particles and heat gun the material into shape.

[@nothanksnoname7567]

You can dissolve the Polyethylene plastics in a solvent like Toluene. However, you would also need to heat the solvent, perhaps getting the solvent up to boiling point, maybe less. This will expedite the process, although you might be able to just wait longer for it to dissolve without the added heat. Not sure exactly. But if you boil the solvent, you also need to condense the solvent vapour back. Anyway, if you could use a solvent, pouring into a mould would be much easier.

[@davidreynolds4684]

I think you should have heated closer to a liquid state. From my reading molding state is ideal at 40 to 50 degrees higher than its melting point. Still looks pretty good. Nice work

[@alicerosa6766]

What if you solder metal around the mold to make it a little higher, then you can fill in with the plastic until melt, then cut off the extra...I dont know, just a suggestion😁😁😁

[@RoshniCS]

Can this work with a silicone mold?

[@Shot5hells]

For HDPE I think it needs to be rigid and heat resistant, since the plastic is very thick. With silicone you’ll distort the mould trying to push the plastic in

[@wrongtown]

Interesting, all the HDPE videos I've been watching seem to caution that as it cools it distorts and buckles if it's not clamped in so I was surprised that this didn't. Any thoughts?

[@SecondLifeDesigner]

Stick the plastic Mickey back into the mold and put it and the mold back into the oven and melt it again. I bet it come out even better.

[@stankyhobo2000]

Great vid i'd love to see more!

[@burrumgirl1]

How would you go laying a square of the milk bottle over the mould, then putting it in the oven. It would probably slump into it and form a hollow figure, if not you could press it down into the mould as it heats, and reheat as you need to, till it is fully spread out and formed. After it is cooled you could melt more plastic and push into the back if you want a solid form. May save you having to cut it out. Very interesting video, thank you.

[@Shot5hells]

I want to try this! Maybe a good way to use less of it too

[@russellcunning]

Why not place the plastic strips directly into the mold and then use the board and clamp idea?

[@1D10CRACY]

I make this Mickey Mouse refrigerator magnet using HDPE (A Milk jug) and a creepy crawler mold.

[@snoopu2601]

1D10CRACY thank you so much for showing me how to reuse recycle plastic ima show kids how to make home made toys

[@snoopu2601]

1D10CRACY you can make a mold using the plastic warp it around something then carefully cut it off what it covered

[@migueljimenez8594]

1D10CRACY Good Idea

[@acidfz1031]

When its cool down. Is it hard plastic?

[@1D10CRACY]

Sure is.

[@2terribletoads631]

What if you returned the mold with the plastic pressed into it back to the oven for a bit and allow it to heat up again? I might possibly conform to the mold a bit better and give more detail? Just curious.

[@adams13f]

How bad would this stink up the house?

[@amandasnider2644]

I have an idea for some experiments you might want to try. If the mold is indeed made of aluminum, and the plastic did not stick to it... Then that opens up a lot of opportunities. First, you should see if putting the plastic directly into the mold and melting it works. I'm not thinking about air bubbles, I'm wondering if it will still seperate after. If it does... Jackpot. You could try getting aluminum cookie cutters, fondant cutters, clay cutters... Lay them on a sheet of baking paper (not wax paper) and fill with the plastic to melt into the shape of the cutter. You could try aluminum mini muffin tins, hexagonal cake pans and jelly molds! Please try this on my behalf! I can't afford to ruin anything.

[@sturgill8511]

Liked and subbed. This is awesome man!

[@CookingwithGringoLoco]

This was helpful, gave me some ideas. Thanks. I suggest a "don't do this unsupervised" below the video while you use a box of flammable matches to hold a very hot pan. Ijs, people would try it.

[@1D10CRACY]

LOL good point! I have a bad habit of using those boxes for all kinds of things and people might actually be silly enough to think or use a box of matches for the same thing!

[@slurp447]

If you use this to make teeth for a plush, can it go in a washing machine?

[@ChuckBryant]

Why 350? Would HDPE flow easier at 375? There's an optimal temperature where it flows easier without catching on fire

[@JohnMarkIsaacMadison]

Have you used 375F? Found a fact sheet that says HDPE burns at over 572F, but I noticed a little bit of burning around the edges at 400F in my convection oven. I was using Meijer plastic bags.

[@larrystone654]

Could you have heated the plastic on top of the mold so that it flows right in?

Would model scrap plastic melt the same way. I got a lot of Gundam plastic scrap from a friend who makes the models.

[@silversecret82]

Can you still use the oven for baking/grilling or only for plastic?

[@1D10CRACY]

Personally I wouldn't make a habbit of it. By what I understand HDPE when not burnt does not offgas any toxins. That being said I am not a chemist and do not understand what is going on with it when being heated. In the future I plan on doing this in a well ventulated area with a dedicated ovan.

[@amandasnider2644]

What is the mold made of?

[@1D10CRACY]

Not really sure, it feels like a cheap tin.

[@ncoutdooradventures6148]

Like you,, all the videos I've seen about "melting" HDPE has been to this same level,, but, if you think about it, there has to be a way of getting it into a more liquid state. Consider the products you're cutting up. They are all shaped into a certain form,, molded. How did they accomplish that? Yes, you can clearly see seams, where they formed more than one piece, and then joined them together, but, as in the case of the milk jug, how did they get the HDPE to enough of a liquid state to be able to form it??

[@soupertrooper3864]

I repaired an old Coleman canoe with a rather large crack in the bottom with milk jugs and a few pieces from a 5 gallon bucket... it's really easy to weld, if you get it too hot it will burn... It will get very very runny before ignition though

[@ncoutdooradventures6148]

@@soupertrooper3864 so,, if the HDPE was heated to a higher temperature, shouldn't it melt? By the way, I know it starts out in little beads, put into a vat where it is originally heated to a liquid state, then extruded,, sometimes directly into molds, sometimes into other processes

[@ncoutdooradventures6148]

@@soupertrooper3864 and yes, I have seen the videos of plastic welding

[@soupertrooper3864]

@@ncoutdooradventures6148 Yes, like I said it will melt but it will not get fully liquid before it lights up and burns... Maybe the pressure in the injection molding process keeps it from burning? I don't have a clue... But I do know for a fact a poly canoe is easy to fix with a couple milk jugs and a couple good heavy brass soldering irons lol

It's not such a great idea to heat up plastic in your kitchen oven. People who do Sculpey and other polymers (and know what they're doing) have a dedicated toaster oven that they keep outdoors.

Vivek Nair any metal with a high enough melting point works. Like steel, Aluminium, brass, copper He bought the mold on eBay. But You could make one with a CNC mill (if you have access to a CNC mill) If not, lost wax casting should work as well.
