See how each of these processes work:Injection molding is used to make plastic parts using two-part molds that, when closed, are injected with melted plastic to form individual parts.Watch the video from ConairGroup for more info:

Extrusion processes use the same plastic melting operation but these is no mold, and the resin compressing screw rotates constantly so that product is created continuously.


Blow molding is a mixture of extrusion and molding where plastic is continuously extruded into a tube shape and then clamped in a mold and blown into its shape with compressed air.ConairGroup
