      abstract     = {The aim of this work is to reduce the warpage of
                      injection-molded parts via a geometric compensation of the
                      cavity as well as a variable cavity temperature control. In
                      the first part of the work, an improvement in shape and
                      dimensional accuracy is sought by using a simulation-based
                      design of the cavity geometry. The presented method aims to
                      control the warpage with commercial injection molding
                      software. Thereby, commercial simulation software calculates
                      the warpage, and a Python program adapts the STL-geometry
                      based on the warpage result and the CAD. For a pi-case
                      geometry with the material POM, the geometry is designed on
                      the basis of the simulation and then validated in practice
                      using a real mold. In total, the adapted cavity geometry
                      shows a warpage reduction by a factor of 3.4. In order to
                      control warpage via temperature, a grid temperature control
                      system is initially being further developed, which enables a
                      dynamic change in local cavity temperatures using heating
                      ceramics. With a self-optimizing control approach, the
                      warpage of a plate-shaped geometry is reduced by a factor of
                      1.1 via the grid temperature control. The initially used
                      concept is then developed further for a stacking box
                      geometry on the basis of simulation, whereby heating coating
                      systems applied to the cavity apply the necessary heating
                      output to reduce warpage. With the help of the heating
                      coating system, a warpage reduction by a factor of 6.8 is
                      achieved for the POM material.},
