Product developments are subject to high technical and deadline requirements, which can only be fulfilled by the use of the most modern CAD systems. 3D data is made available using the construction systems, which does not need to be edited, and can be used throughout for all the development steps extending to the tool construction. It therefore goes without saying for the engineers of Impetus Plastics Engineering that the CAD models take account of both draft angles and radiuses and also the tolerances.
