In this article you will learn the Extrusion basics and how the community is replicating it and improving it from around the world. The Precious Plastic Extrusion machine was originally designed and developed at the Design Academy by Dave Hakkens back in 2013. Then, during version 2 it was refined by Kees and released open source to the world in 2016. Fast forward to 2020, and Precious Plastic released the Extrusion Pro, a bigger and stronger machine to fit the growing needs of the community.

It’s ability to work with moulds or free-hand makes the Extrusion machine a very common choice amongst the Precious Plastic community. And since it can now make beams and bricks its popularity has increased many folds with hundreds of people making inspiring things with it.
The fundamental functioning of the Precious Plastic Extrusion machine is quite simple. Heat the plastic, melt it, transport it with a screw, press it in a mould or work with it freehand, cool it and you’re done. Let’s look at it in a bit more details:

1. Set the machine to the correct temperature. This depends on the plastic you’re going to recycle. Over the years we found the Extrusion machine to work best with PP and HDPE.

2. Load the barrel through the hopper with your recycled plastic of choice. Make sure the hopper is quite full as the plastic will be quickly used up.

3. The screw, powered by a motor, will transport your shredded plastic further into the barrel where the heating elements are.

4. The heating elements plus the pressure created by the screw will melt the plastic. As the plastic melts it can get through the nozzle.

5. At this point you have two options: you can work with a mould or freehand to create your recycled product.
