Define, analyze, adjust


When it comes to efficiency in thermoplastics part design and production, design engineers often rely on Computer Aided Engineering (CAE) for assistance. CAE utilizes fast computer technology for calculating complex part geometries to bolster analysis, simulation, design, manufacturing, planning, diagnosis and repair.

The three fundamental phases of CAE are:

  • Pre-processing – a model is defined, and the relevant environmental factors are determined.
  • Analysis solver – data analysis is usually performed using high-powered computers and specialized software.
  • Post-processing – visualization tools are utilized to validate the part and process and adjust the design and production process, if necessary.



Through the use of the injection molding simulation and structural analysis components of CAE, design engineers can gather more specific data for their particular part and process to further refine and optimize design and production.

The results of CAE analysis lead to a better understanding of physical relations within the part, a significant reduction in the number of prototype parts made, increased product development speed, and assistance in determining the optimal part design.

Since CAE cannot account for all variables, designers use physical labs for verification. Covestro uses his own injection molding and test lab for material data and processing validation. CAE is meant to serve as a complement, not a replacement, for design engineers. Covestro offers CAE services and related support to our customers.
