This paper also analyzes and calculates the relevant data of the cup, and whereupon selects the injection machine and injection technique, determines the design idea, makes the general drawing of mold, and some nonstandard drawings with Pro/E and AutoCAD, to obtain the final theoretical design. The design lays a foundation for future design.
