Plastic fails differently.


When it comes to performance and durability, plastic and metal can go head to head in many applications.


But when it comes to designing and manufacturing, they are two completely different materials.


Relying the same tools and methods to model plastic part performance—especially as it relates to compression and tension—will not yield accurate results.


Why not?


Because, unlike metal, engineering plastics are reinforced with glass or carbon fibers, and those fibers—their orientation, where and how fast they flow into the mold—affect the performance and failure points of the component.


Not factoring in anisotropic (or multidirectional) fiber orientation and flow patterns is often why the prototyping stage for plastic parts becomes drawn out and very expensive.



For example, on regular simulation software, three plastic bumpers with the exact same geometry—but with different injection gate locations—would look identical. On ULTRASIM®, each bumper would not only look different, they would also test differently.


Likewise, when performance models do understand and account for these variables, the results are not only more precise, but they can be improved by changing variables like injection gates and velocity. This insight is what sets ULTRASIM® apart.
