Many factors affect plastic part design. Among these factors are: functional requirements, such as mechanical loading and ultraviolet stability; aesthetic needs, such as color, level of transparency, and tactile response, and economic concerns, such as cost of materials, labor, and capital equipment. These factors, coupled with other design concerns - such as agency approval, processing parameters, and part consolidation - are discussed here.

While engineering resins are used in many diverse and demanding applications, there are design elements that are common to most plastic parts, such as ribs, wall thickness, bosses, gussets, and draft. We outline these general design issues, as well as others you should consider when designing parts made of thermoplastic resins.

Here we show how to use published data to address the unusual behavior of plastics in part design, and to show how to take advantage of the design freedom afforded by molding processes to meet your structural requirements.

Show you how to use some basic structural formulas and how economically to design a part for stiffness. There are discussions on long-term part loading, designing for impact, fatigue applications and thermal loading.
