1) Injection molded container
Plastic material is introduced in pellet form into a "hopper" positioned at the top of a machine and forcing it along a horizontal chamber or "barrel" of an extruder by means of the rotation of a screw. The plastic material is heated as it moves through the barrel so when it reaches an open cavity, it is a molten mass ready to assume the configuration of the mold. The mold is closed and pressure is applied to form the container. Once the pallet is cooled and taken from the mold, it can be further processed into secondary operations such as painting, trimming or fastening.
