@btmetz Thank you for the tip, looks easy to pick up.

I hope to make a few sheets of the same plastic and then use this technique to make a bench or table top.

thanks again.

As the heat press only heats from the top, and the hot side warps more I tested an idea – what if I make this hot side cool the fastest? – after the sheet is done in the press I place the sheet hot side to my shed floor and add 2 slabs and 16kg of weight on top. Seem to work well

So been experimenting all today and have finally worked out my warping problem, well a large part of it. Made 2 really good sheets that are smooth. Made a little table with 1 of the sheets, super stoked with it!

G’day occupypp,

no I haven’t but I do fine that the drill shavings and plastic saw dust comes out really well, as I am only using a house hold blender at the moment it’s cuts the plastic up okay enough for the molds and sheet I’m trying to make I will now save all my smaller dust and see how that goes.

Hey plasticas,
Yeah I have tried that to and nothing so far.
I have gotten the warp down to about a 0.5cm in the middle but this looks shithouse still when you cut it or anything.
I’ll add updates as the come.

Thanks again guys for the help and tips.

Hello plastacs,

No thank you for your feedback always appreciated.

Yeah I have been using the same stone blocks and squishing the sheet between that,

I have found that as the heat press only heats from the top down. This has something to do with the warping because if I flip the sheet and cool it down in the same stone blocks they come out straighter. I am wanting to add a tin sheet to my mold so it can hold more heat on the bottom as well and see how that goes.

It’s crazy what you can make from a good sheet tho.

Thanks again for your help.

Hey humans,

just an update on my progress with my heat press,
1. Have been able to constantly make 29.5cm by 25cm by 1cm.
2. Warping aaahhhh! Very close to working this out but frustrating at the moment.
3. I have forgotten most of my woowork skills from school but they are coming back slowly, these are just proof of concept mainly.

Any hints or tips let me know.Thanks.Adz.

Hello fellow humans,

Here is an update on my progress,

With my first two sheets I made a little table that is quite sturdy and looks really cool. As I did very little to pretty it up.

I then made a cool af looking sheet out of pp and hdpe bottle caps, with a new cooling technique just squishing it between two concrete slabs, about 15kg each.

I just made a mold for my heat press that is easy to fill, flip and pull apart to clean or get stuck plastic out. It’s just aluminium cut to fit my silicon sheets with a threaded bar through it held together with butterfly nuts. This seems to work so far. This makes a 34cm by 26cm sheet.

My first test in this I used 550g of abs plastic.
200c for 20min each side. Then cooled down between slabs of concrete. It’s super smooth and not as shinny as the other test but still nice to touch. Quite strong but could of gone hotter.

I am going to try and make other things with these sheets, if you guys have any ideas that you think might be easy to make please let me know.
I am looking for things around offices and schools as I work in a uni.

I need to look into different ways to join plastics as well but so far very happy with my progress.

Thanks everyone and keep being cool.
Adz.

Test #3

200c for 20min each side, cooled down under a concrete slab.

Shiny finish, smooth to touch, very strong.

Test #1.1

I cut my first sheet down into a 15cm2, this was the smoothest part of my first sheet.

Test #2

I got 2 silicone baking sheets (thanks for the tip) molded with aluminium tubes again this time to the length and width of the baking sheets.  21cm by 38cm. 20min each side then 10min under a large weight.

The mold moved and didn’t keep the plastic in the spot as you can see. But over all very happy with it. Smooth and strong, wanna try and build with this soon.

Thanks
Adz.

My first real test and I’m happy with the results.

A lot to learn from this but just happy to have a start.

Test #1 200g of mixed plastic (I think it’s hdpe)
200 degrees Celsius for 20min.
Inbtween aluminum tubing to make a 30cm by 15cm by 1cm sheet.

This seem to almost work, the tubes are not welded together so they moved to easy.
Once I have the mold welded together I am going to try again, however after 20min I waited 10min for the sheet to cool in the machine still pressed then took it out and placed a large stone tile on the sheet to weight it down.

Over all happy with the first test and can’t wait to see what I can make.

Hello @plastacs,

Thank you so much for sharing your insight and tips with this, I haven’t had the time to test it the way I want to yet but will this coming weekend, so I’m very happy to gather notes beforehand.

I will try to make some kind of squishy machine for the sheets in time but for now I will try that tin sheet idea.

I have found that it doesn’t seem to take too long once it is heated up to start to melt. I would love to try molds in this as well.

I will keep this page updated once I get to it.

Thanks again guys.
Adz.

Thanks guys for the tips,

I checked these guys out that’s amazing what they are doing.

Thanks mate I will give it a try, I’m just trying to make a 1cm thick sheet anywhere from 20cm2 to 35cm2. Hopefully after a little r&d I’ll have this.

As for the machine it’s amazing, I think once I have worked out the mold this will be able to start a small production for sheets.

Once I have some update I’ll let you guys know.

Keep up the good work guys.

@donald

Thank you for your quick reply and clear ideas I will give these a try and see how they turn out.
They are 2cm thick and weight about 100g, so post might be expensive, I’ll look into this as well.

I will haha thank you.
