The development goal for the 3K injection moulding tools, reducing distortion in the frontal area, was achieved with homogeneous temperature distribution in the cooling phase of the injection process. Three-dimensional display results and animations of the distortion clarified the behaviour of the end product and simultaneously helped us design and optimise the conformal temperature control. In addition, we were able to precisely analyse the interaction of the various components, materials and geometries. Both aspects, transparency and optimisation, resulted in a high-quality component. This meant that overall cycle times could be shortened, production costs could be lowered, tool post-processing could be reduced to a minimum and a significantly shorter development process could be achieved.
