Comparison of products - Many cheap designs still continue being derived from "metal parts". In the collection commencing here the authors set out to describe the details that require particular attention when designing in plastics instead of traditional materials.

Several basic material characteristics

The properties regarding plastics materials will vary over a considerably wider range compared to all other architectural materials. Through the addition of fillers/reinforcing products and modifiers the house profile of practically base polymer might be radically altered. Easiest properties of plastics, nonetheless, form a marked contrast to those of metals. By way of example, in a special comparison, metals own higher of architectural thermoplastics are higher by orders regarding magnitude. To produce practical parts in plastic and simultaneously save costs, radical design modification is normally necessary if that plastic is used to replace shiny. This process affords a chance for complete redesign in the component with doable integration of capabilities and geometric simplification.

Several material behaviors

Plastics sometimes exhibit contrasting behavior to which of metals under a similar service conditions. Because of this, a functionally successful, economic design within cast metal can simply fail if repeated in plastic by using excessive haste. Plastics designers must therefore be familiar with the properties of this group of products.

Since plastics tend to be less tolerant regarding faulty design compared to metals, greater attention needs to be devoted to accurate industrial design within designing plastics elements. Every design method must therefore focus on a thorough in addition to precise analysis of all requirements and boundary conditions.
