Roymatek supports die casting and injection molding customers in understanding what really happens inside their parts and tools. Our CT systems reveal porosity, cold shuts, shrinkage, voids, weld lines, fibre orientation and warpage across the complete component volume, from first shots to long‑term serial production. Engineers use these 3D insights to shorten tool tryout, validate cooling layouts, correlate internal defects with process parameters and stabilise dimensional performance over the full tool life. In cooperative laboratory work with Honda, Roymatek applies this capability to demanding automotive components, turning detailed CT analysis into practical guidance for tool optimisation, process windows and robust series quality.
