Production apparatus for forming plastic molded articles

A plastic forming apparatus for making plastics from at least two different particulate plastic materials, comprising:

• at least two complementary open bare surface molds, each mold being mounted on a rolling cart, where said molds are capable of being moved along a trunion track and capable of being heated;
• said molds having at least one open bare surface with a sealing edge for ultimately mating with the other open mold, said open bare surface being disposed for receiving the particulate plastic materials;
• at least one hopper for dumping a first particulate plastic into each of the open molds individually, said hopper having at least one distributor arm with a downwardly facing distributor tube including louvers for opening and closing the louvers to distribute the particulate material into each of the individual open molds, said hopper being capable of being recharged with surplus particulate plastic material after the molds are used;
• a supply of heat for separately heating the complementary molds;
• a second hopper for dumping a second particulate plastic into at least one of the molds, said second hopper also having a distributor arm with a downwardly facing distributor tube including louvers for selectively opening and closing the louvers to distribute the particulate material into the at least one mold, said hopper being capable of being recharged with surplus particulate plastic material after the molds are used;
• a means for rotating the molds to remove excess particulate plastic material and a means for bringing the two open molds together to form a cavity therebetween,
• a cooling station for cooling the heated molds;
• a track for rolling the two carts from under the first hopper to a position under the second hopper and then into the cooling station;
• and
• a means for moving the closed cavity molds into said cooling station.
