This is the part of the molding machine that loads the plastic. The plastic comes in small beads that come in bags similar to what you would buy soil in. They are then dumped into large cans. This part of the machine vacuums the beads out of the can and then are loaded into the machine. The beads fall into the funnel in the picture and then are fed into the machine where they are melted down to be injected into the molds.
