Screw diameter: Selection is based on output requirements;

Screw length-to-diameter ratio: Design is usually related to the material formulation; relatively speaking, a longer screw provides better plasticizing ability. Beyond the basic screw length, the design and machining accuracy of the thread path affect the extrusion output of mixed materials.
