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. Read More »

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.
