Abstract: An electromagnetic coaxial driving injection apparatus, having a linear motor for driving injection and a rotation motor for metering. The linear motor and the rotation motor of both the injection and metering motors and an injection screw are set on a common axis. A connecting device connects moving parts of the motors with the injection screw.

From the packaging area, the parts are moved to a relatively small shipping area where the batch of parts are already ordered to be effectively loaded directly onto the transportation vehicle. As the finished parts come off line in the batch particular to the transportation vehicle, a large shipping area and inventory area is avoided.
