Acrylic molding in the oven

post #1 of 31
Thread Starter 
As i dont knew where to post it ill post it here. Sorry also for my language skills ( this is not my native language)

So first of all be safe when you gonna be doing this. A lot of hot surfaces and much more things that can hurt you seriously.

Ok now make sure you have items as you gonna be needed for this:
A electric of gas oven. biggrin.gif
Gloves ( same as you use for taking stuff from oven when you baking something)
Some tin foil.
A form that is near or is the same as a thing you need to mold.
Acrylic piece, use a smaller piece, and why? im going to try explain all that thing.




So lets start from a temperatures. Some sources say that you need to heat up oven to 300 Celsius, some others say that you need a 200-150 Celsius. From mine expierence i could say that best of all is 200 Celsius, why? Because you dont need to wait for a 15mins ( if you use a thick piece of acrylic) to heat up. I used for this tutorial a 200 C and i wanted to leave it for a 10 mins. And this was my mistake because acrylic got bubbles and also just stick aroung a tin foil. ( i was at the same time making a dinner biggrin.gif )
Some pics:
Use a tin foil because acrylic doesnt stick up to it if heated not too much. ( and dont try to make a dinner when you heating up a acrylic biggrin.gif ).

Oven that i used is a small electric oven, i turned on a bottom and top heaters. Also tried to bend acrylic pieces by heating em directly holding it beneath the heating element. And it worked fine to me smile.gif

After you heated a oven lets say to thoose 200 C put it in. And try to see if it is heated enough just trying to lift corner off with something like a screwdriver ( flat) or something similar. Dont go any far from it and dont leave it for a long time,
When its is solf enough to bend it take it from a oven, and be quick and make sure you wear gloves. Take it gentry and there are some methids how to mold:
1, Wrap it gently around form you gonna use
2, Put it on top of form you gonna use and watch how slowly it takes shape
3, make right decission smile.gif
Also if its gonna be round gently press ir around a form, and press not a one spot but go all over it. Do this till acrylic gets stiff enough then you can speed up process with some cold water to make it go hard faster.
This photo shows how i made it by holding with hands beneath the heating element in oven

And this one shows what a big mistake i did leaving fo a longer time it alone in oven, it got many bubbles, and some random stuff

Ill try to make this thread as much informative as i can find right words and post a failure i did with last piece of acrylic smile.gif
If you have any questions just ask as PM or post it here. Ill try to answer them smile.gif

You may want to post a drawing,with a caption "I want to make this flat piece of 4mm acrylic look like this when I am done".It allows people to get a idea what you are attempting (except simply bending acrylic).

im going update this tomorrow, this was only a guide how to mold it, also gonna add some drawings hot to bend it around objects to get a shape
post #7 of 31
Would it be possible to mold acylic to a shape like the picture below? Its a 400r side panel.

That or would it be a wise decision to make multiple pieces and then just join them.

this is kinda a challenge, yeah if get right temps in heating acrylic you could get this shape or you can put a piece of acrylic on that side pannel, and heat it with heatgun. It should take form from its own weight smile.gif

Edit:
You gonna need a bit taller form like that side pannel to make perfect fit when its molded, i just saw this case pics

So heres a bending pic i made with Ms paint biggrin.gif I dont know if it would help a lot because my explanation skills gonna be bad biggrin.gif
1. Show that when you heated it enough go to figure n,2
2. put it gently on flat surface that the heated end would look dont
3, very gently press that heated end to take angle you need and hold it with a piece of something flat and wait till it gets hard.
4, And wuola you got your angle righ way, also you can use a heatgun to do this one

Acrylic molding around a surface
1, when you heated it enough in the oven
2, take it out very gently with gloves and dont press it with your fingers much because gloves can leave its texture... and put it on the form
3, gently wrap around and press a little bit. You could also rub it all the way down on sides to take better form
4, and picture said what to do with this one
