Plastic Part Design Principles

Catalog description

2 Lecture Hour(s) 2 Lab Hour(s) The course teaches students how to recognize the part design features and material issues that either help or hinder the manufacturing process, and offer the part and mold designer guidance in designing products for manufacturability. An overview of plastic part design, material shrinkage and flow characteristics, mold design, and injection molding is included to help students develop an understanding of the complex relationship of these different factors and how factors combine to create problems in the molding process. This course will explain the causes of, and means to solve many unexpected problems including shrinkage variation, warpage, no fills, gas traps, weld line locations and effects, variations in part size, shape and weight, flash, core deflection, and steel fatigue.
