Plastic Product Design With NX

The document discusses plastic product design with NX software. It covers plastic materials and their properties, design considerations for injection molded parts like wall thickness and draft angles, tooling surface design, and implementation in NX. This includes analyzing molded parts, defining the cavity and core, designing the parting surface, adding standard mold components, and creating sliders, gates, runners and a cooling system layout. The goal is a detailed mold design in NX that considers the plastic material and injection molding process.
