DIY Roto-molding machine
 |
||
This is an at-home roto-molding machine I whipped up in about 3 hours one night. To build one like it you will need:-About 20 dollars worth of Fisher Price Construx from ebay-A drill (DeWalt's fit nicely, but anything should work)-A few wood screws to hold down the Construx-A piece of scrap woodFor my casting material I like using Alumilite and Polytek resins, they are both REALLY easy to work with and fairly cheap. Any RTV resin should work well as long as it has a short set time.

Great job! As someone who works in the industry, I thought that you did a fantastic job demonstrating the process.

video juice ran out?give me a break, he just didnt want us to see his failed roto-mold process.but i will admit, it looks like it would work.

Good point. I doubt this could handle the heat necessary to melt resin pellets. Seems an erector set is required.

Rotomolding is most often associated with really big plastic playground toys (Little Tikes and Step 2 come to mind), for some large car interior pieces, and for urban vinyl toys. There are a number of practical advantages (e.g. molds are relatively simple) and monetary advantages (e.g. it's a comparatively low-cost investment process).

why reinvent the wheel. so whats the NEW part?

Another ingenious use for construx. How do you set up the gears & pulleys to get the inner ring to rotate?

Ingenius idea to use construx to build it.Only problem with Roto-moulding is it dosn't work so well for complex shapes, as some surfaces wont have as much material flowing over them, and you end up with thin spots. Works great for simple shapes though.In my old job, we used this proccess for makeing plastic water tanks, although we used plastic powder and heated it to 180c during rotation.

Yes, construx. The amazing building set that should not have been discontinued in the 80's.
