The design of product manufacturability analysis, and in turn to the mould structure form, determine the injection machine number, formwork design, gating system design, the ejection system design, water design, processing of two-dimensional figure, etc., showed the NX/Mold Wizard software can accurately for injection Mold design. Secondly, according to the product shape and mold production drawings of evaluation design hot runner system, embodies the superiority of hot runner technology. Through this design, to understanding of the process of injection mold design and all need to pay attention to the details of the design process.
