Salt core technology for high pressure die casting
Production of hollow parts and complex undercuts in high pressure die casting. In high pressure die casting (HPDC) undercuts are only producible by using complex and thus high-maintenance sliders. Until now it is not possible to produce hollow cast parts by means of this technology. Known sand cores from sand- and low pressure die casting with their organic and inorganic binder systems are not suitable for the application in HPDC since they cannot cope with the process specific parameters. The use of lost cores made from salt constitutes a solution. After casting, the core can be removed completely from the part with a pressure water jet making sand-free castings and the integration of complex undercuts possible in HPDC.
