great site!!
i am building my first vac-form machine. 24x 48
first question...what about the smell?
is it enough to bug the neighbors?
i will be using .125 + material so what about mold heating?
not able to find any related posts yet.

Hey Dale, Welcome to the forum!
I run a 24x48 vacuum former using black ABS primarily 1/8"-1/4". Unless the sheet is seriously overheated there is usually not too much smoke or smell. So unless your neighbors live in an upstairs apartment the smell shouldn't be too bad.
With black ABS, the mold's I'm using don't need heated. I don't know if there are other plastics that might need pre-heated molds. Post up picts of the progress on your machine & projects if you get the chance!

Welcome to the board! Hot plastic does not make much smell, and HIPS is pretty easy to work with. Noise may be a bigger concern!

Hi folks,
Thank you for the greeting and response to my first of many questions.
Is there a plastic for dummies hand book???
Which plastic for the application has me baffled!!!
I have downloaded the spec sheets for different suppliers but I would have to be an engineer to understand what info is being presented to me.
My plan is to build a container for extreme sports.
My parts will be exposed to water in rivers and creeks.
Also they will come into contact with mild abrasion from sand and gravel.

Well, my suggestion is to determine what you NEED from your plastic, and test several types before committing to the final one. HIPS is a good plastic to learn the art of vac-forming, as it it cheap and forgiving to folks learning how to vac-form. Once you have some test pulls under your belt, you can then experiment with ABS, PETG or polycarbonates.

Thank you. Great advice. And it is always fun to experiment with stuff.
Is there a wiring schematic posted for the coiled wire heating elements?
I would like to use 220v in three segments.
Are the segments isolated or connected?
Are they wired red-black-red-black?
It seems the easiest way to build a heater is to use two heating elements from an old oven, then use its own temp. Control and thermal couple.
