The compression machine consists of an electric kitchen oven to heat the plastic and a carjack to apply pressure to the mould. The process is generally slower than the other machines but it allows for bigger objects to be crafted. This machine can also be used to create new raw material like big sheets of plastic that can be further worked on to make new products. When mixing different coloured plastic, the compression machine gives a specific flake-like look to plastic that can be used to your advantage
Pro tip: Heat and melt the plastic with the mould open, apply the top of the mould only after the plastic is fully melted and apply pressure.

How it works
You can find all the technical drawings to build this machine in our download-kit. They are divided into different steps and contain all the dimensions you need to build the machine.
Below you can find a 3D visual of the machine, just to give you a basic understanding how it works, click the button to turn it around. Detailed CAD drawings can be found in the download-kit.
The compressor is pretty basic, it heats and presses plastic into a mould. This machine enables you to make a wide variety of products- it all depends on your mould and technique. It’s easy to make little bowls or containers, however, you could also be making flat sheets or solid objects which you could use as a starting point to work with traditional tools.
Built by the community
We are always amazed to see what our community can come up with. Below is a small selection of compressions built by people in our community following Precious Plastic drawings. Truly incredible!
