I am selling my injection machine. It uses a two pot system and the plastic is cold and passes through the heat exchanger in the head and you simply lift the lever and the mold is held in place by a pneumatic plate and fills the mold solid and no voids inside it. You can use just one pot and fill your molds or the two pot system and make laminate molds (two colors. The molds used for the machine can be used if less than 5"s tall. I'm in zip code 23834 Virginia. I can send pictures if requested. thanks, G.
