There’s a wide range of source contributing to warped or inconsistent sheets
Inconsistent heating across the plate. This isn’t easy or cheap to solve The process, eg: wrong melting times Plastic source, contamination, flake size Rib structure of the sheetpress (currently, the 1m version can be considered a safe ballpark) Bend heat plates, over time These are the workarounds, fixes we know of

Compression Machine
Build a Compression Machine What is this machine? The compression machine is basically an electric kitchen oven to heat the plastic, and a compression mechanism (a carjack) to apply pressure to your mould. The process is slower than the other Precious Plastic machines but it allows for larger moulds to be used. It can be used to create raw material, like sheets or shapes that can be further worked on to make new products and gives a specific flake-like look to the plastic (which looks amazing!

Extrusion Machine
Build an Extrusion Machine What is this machine? Extrusion is a continuous process where shredded plastic enters the hopper, heated and pressed with a screw through a long barrel. The output is a steady line of plastic, and as this machine runs continuously, if you have enough plastic and a well-streamlined process you could (technically) be recycling 24/7
Tip : to increase efficiency and diversity we recommend to upgrade the extruder- YouTube with the compression screw.

Injection Machine
Warning / Remarks
This machine is known as rather disapointing and difficult to operate. Please consider an arbor injector instead. Plunger diameter should have a clearance of exactly 0.1mm to the barrel. If applicable, please use a brass or bronze tip for the plunger. This reduces contact to the barrel and friction. Using plumping connectors adds unheated ‘dead zones’. In return, plunging becomes more difficult. The original v1 uses a too long plunger.

Plastic Intro
Melting temperatures There are different types of plastic and one reason why it’s so important to separate them is because of their melting temperatures. They all reach a liquid state at a different heat. In order to make new high quality items it’s important to know at what temperature each plastic melts as well as at what temperatures different types can be moulded.

Robotic sorting
Robotic Sorting Why Sorting? 68% of the world’s plastic can’t be sorted by automated recycling facilities. While local recycling works differently in every country, typical sorting facilities may identify and separate PET and HDPE plastics, but due to the high cost of sorting, the rest of the plastics will likely be left mixed. These mixed plastics may be sent on to other waste facilities to be burned for energy, they might end up in a landfill, some are shipped overseas, and in the worst cases they are piled up and burned in the open air.

Sheetpress
Warning / Remarks
This machine requires precision machining (cartridge heaters, rails, frame). Structural issues, creating uneven pressure across the press plates, resulting in uneven thickness. Expensive to build. Realistic costs to make it good are somewhere at 10000 Euro. 15000 Euro with all features and safety measures. Issues with heat distribution, resulting in warped sheets. Inefficient heating. Our recommendation: please wait for a better design but also better documentation. There’s a wide range of source contributing to warped or inconsistent sheets
