The injection molding machine can be separated into different units.
At the beginning of the injection molding process stands the injection unit.
It contains the hopper, through which the granule rinses inside the cylinder with the screw.
The rotating screw and the heating rods at the outside of the cylinder cause the melting and homogenization of the plastic while the meld is transferred to the tip of the screw.
Here the plastic is metered for the process.
At the end of the injection unit is a nozzle through which the melt is pushed into the mold by the forward moving screw during during injection.
