Joseph sez, "This is an exclusive Lego set that you can purchase on the factory tour in Denmark. It has semi-functional injection molding mechanics. Really a neat toy."
The set consists of two moulding machines, the first was a replica of the original hand operating injector back from 1949. The second, Larger one is copy of the current Moulder that LEGO uses today that … well made the bricks that made this model :)
Each model has working features – the little one can 'press' the mould together. Where as the large one has a little slot to put in 1×1 round plates in (or raw abs) , followed by a separate mechanism to 'press' the mould together. the little 1×1 round then drops down an incline and into the yellow basket below – where it waits to be whisked off by machines to storage.
